Still Calculable Connections: Israeli Nuclear Deterrence and War with Iran

The author, has been lecturing and publishing for more than fifty years about Israel’s “bomb in the basement” and its national nuclear deterrence posture.

“The worst does sometimes happen.”-Friedrich Dürrenmatt, Swiss Playwright

The author, Emeritus Professor Louis René Beres, has been lecturing and publishing for more than fifty years about Israel’s “bomb in the basement” and its national nuclear deterrence posture. Israel presently remains at war with a variety of Iranian-backed proxy forces (both Sunni and Shia) in Gaza, Lebanon, Syria, Iraq and its own borders. Plausibly, Israel will soon “come to blows” with Iranian military forces directly. This action could quickly become an encounter with exceptionally high levels of regional destruction. In a worst-case scenario, such an action could include the actual use of nuclear weapons. To prevent this unprecedented scenario, or “merely” to mitigate its effects once a tangible nuclear struggle was already underway, Israel will need to update/upgrade its operational focus on credible deterrence. Inter alia, any such effort should include (1) variously incremental shifts from deliberate nuclear ambiguity (the “bomb in the basement”) to selective nuclear disclosure; and (2) suitably refined versions of the so-called “Samson Option.”

               In the following argument, speculative narratives about Israel-Iran war are presented straightforwardly. These critical scenarios are not in any way residual, contrived, or obscured. Plainly, sober expectations of direct military conflict between the Jewish State and the Islamic Republic rise to the top of each day’s major news compilations. Though the most immediate war precipitants would likely be ties linking Iran to the criminal actions of its terror surrogates,[1] there would also be belligerency problems concerning a Palestinian state. Prima facie, any such state would be irredentist, destabilizing and relevant to plausible regional war scenarios.

               Why should there be any such connections? To begin, “Palestine” would shrink the Jewish State’s already limited strategic depth to militarily meaningless levels. The entire State of Israel – even before a hostile Palestinian state had been carved from its still-living body – is smaller than America’s Lake Michigan. Israel’s current strategic depth is not just “already limited.” In objective military terms, it is little more than a national defense caricature, an oxymoron, a fearfully self-evident contradiction in terms.

               In essence, this sums up Israel’s geo-strategic war background. With such sobering metrics in mind, Jerusalem must inquire: How should a perpetually-beleaguered Israel refine its nuclear deterrence posture to best prevent or manage an impending war with Iran? In any purposeful reply, adjustments and clarifications of Israel’s nuclear deterrence posture would need to focus on (a) essential weapons (both offensive and defensive); (b) essential weapon system infrastructures; and (c) essential correlates of threat credibility. Regarding this last requirement, Israel will need to calculate optimal equilibrium points between “escalation dominance” and war avoidance or war mitigation. Moreover, because all relevant scenarios would be without precedent or sui generis, Israeli decision makers could never fully determine the accuracy and utility of these assorted calculations.

               What should be done? Certain specific questions will need to be raised and answered, sequentially and dialectically[2] How should these complex analyses proceed?

               One singularly revealing expression of the current world’s balance-of-power[3] could be summarized as “Cold War II.” This is not because an always-implicit US-Russian rivalry is more immediately critical than the core structure of global anarchy bequeathed at the Peace of Westphalia in 1648,[4] but because such rivalry has already become “tri-polar.” China, with its tangible links to Pakistan, North Korea and Iran, is a major actor in the rapidly dissembling Middle East. Inevitably, such links would involve various “peremptory” considerations of authoritative international law.[5]

                For planners of Israeli nuclear strategy, US-Russia-China antagonisms should be studied together with Israel’s weapon systems and its nuclear threat credibility. These system-defining antagonisms are already in constant flux and changing in foreseeable and unforeseeable ways. An ominous example would be any adversarial preparations for actual nuclear warfighting.[6]

               There will be further details. Superpower antagonisms, tempered or buffered by international law, could become vital or determinative for Israeli nuclear deterrence. In part, these primary antagonisms could sometime even be impacted by a “biological variable,” that is, by disease pandemic. In principle, at least, asymmetrical levels of success in dealing with future pandemic outcomes could make one side or the other more or less aggressive.[7] Accurate recognition of such asymmetries would then represent a tangible part of Israel’s calculable “equation.”

                Ultimately, a great deal will depend upon the precise manner in which this resurrected and now China-augmented polar rivalry could impact the equation and, derivatively, the critically underlying elements of Israel’s strategic posture.[8] This discoverable manner of impact could depend in part on Jerusalem’s multiple and overlapping national nuclear power alignments – with Russia, the United States, China or North Korea, which carefully maintains close ties to Iran.

               Prior to such complex considerations, much will depend on (1) the expected rationality or non-rationality of each national nuclear power[9] and (2) the expected interactions (synergies) between these nuclear adversaries and their respective alliance partners or clients. Regarding the first concern, Israel’s planners will need to bear continuously in mind the wisdom of German philosopher Karl Jaspers’ Reason and Existence (1935): “The rational is not thinkable without its other, the non-rational, and it never appears in reality without it.”

               “Everything is very simple in war,” counsels Carl von Clausewitz in On War, “but even the simplest thing is difficult.” This generally useful insight remains persuasively valid not only during periods of active military conflict, but also in those unsteady periods of latent hostility that obtain between still-possible or still-impending wars of aggression.[10]

               Israeli analysts and decision-makers will also need to take more specific heed of future pandemic, a variable that could prove determinative for several reasons, including potentially plausible effects upon decisional rationality. These effects would need to be explored among friends as well as foes and would make each adversarial party (state, sub-state or “hybrid”) wary of the others’ “pretended irrationality.” This “pandemic variable” could make “normally” complex decisional calculations denser and more difficult to decipher.

                The idea that considerations of operational difficulty may obtain “only” during a “cold war” was already described by seventeenth-century English philosopher, Thomas Hobbes. In his classic text, Leviathan, this early political thinker (one widely read by the founding fathers of the United States, especially Thomas Jefferson) opines that a condition of war exists not only during periods of “actual fighting,” but whenever there exists “a known disposition thereto.” Today, such a “disposition” is instantly recognizable between Israel and Iran.

               Even during the expansive pre-nuclear era in international law and world politics, a precarious logic of deterrence obtained within the global state of nature. Already, there had been operative an evidently fearful condition of raw competition, corrosive violence and seemingly perpetual anarchy. Despite considerable nuance from century to century, and even from year to year, this so-called “balance of power” has continued since the 1648 Peace of Westphalia.

               Long before the advent of nuclear weapons, the worst “state of war” (including ones without any “actual fighting”) would have been characterized by a “dreadful equality.” In this condition, world politics would take place within a broadly chaotic bellum omnium contra omnes, a bewildering structurewherein “the weakest has strength enough to kill the strongest.” In such blatantly “opaque” circumstances, of course, the potential sources of decision-making bewilderment would expectedly multiply.

               In any such worst case configuration – one wherein nuclear proliferation would continue without any meaningfully correlative legal inhibitions – the lives of individual human beings and entire states would quickly become (per Thomas Hobbes’ Leviathan) “solitary, poor, nasty, brutish and short.” For Israel, the shifting parameters of Cold War II and certain related issues of Iranian enemy rationality could soon have indeterminate or foreseeable effects upon its presumptive nuclear doctrine and strategy. This includes those diverse issues surrounding any needed policy choices between “nuclear ambiguity” and “nuclear disclosure.”[11]

               For Israel, a state altogether lacking in strategic depth,[12] a state smaller than America’s Lake Michigan, the former posture has prevailed without serious challenge. A diminishingly useful stance, it is often referred to as Israel’s “bomb in the basement.”[13] At some point, modifications of this no-longer-viable stance could require certain coinciding Israeli resorts to “anticipatory self-defense.”[14]

               Until today, in principle at least, Israel’s national nuclear doctrine and posture have remained determinedly ambiguous. At the same time, traditional ambiguity has already been breached at the highest possible level by two of Israel’s prime ministers, first, by Shimon Peres, on December 22, 1995, and then by Ehud Olmert on December 11, 2006. Peres, speaking to a group of Israeli newspaper and magazine editors, had affirmed publicly: “…give me peace, and we’ll give up the atom. That’s the whole story.” When Olmert later offered similarly general but revelatory remarks, they were widely (but perhaps wrongly) interpreted as “slips of the tongue.”

               Today, as Moscow and Washington are once again becoming bitter adversaries –  in part because of their different positions and involvements throughout the Middle East; in part because of Russia’s war of aggression against Ukraine –  a basic doctrinal question should be raised in Jerusalem:

                Is comprehensive nuclear secrecy in the survival interests of the Jewish State?[15]

               To respond “cost-effectively” to this question, Israel should start from the assumption that in any such many-sided strategic matters, “truth” could be expansively counter-intuitive. A full answer to the query should be grounded in tangible expectations and exigencies of formal strategic doctrine.Whatever else Jerusalem may have in mind concerning such policy-shaping doctrine, it’s response ought never be just a series of incremental decisions or unreflective”seat-of-the-pants” policies. Israel could never have any need for positions that are casually invented or re-inventedfrom one security crisis to the next.

               In essence, fashioning Israeli doctrine ought never to consist of disjointed or narrowly ad hoc calculations. Any purposeful loosening of Israeli nuclear ambiguity would need to be subtle, nuanced and indirect. Contrary to the oft-parodied views of such prospective disclosure that may be found in popular news stories, on the web or on television, this loosening would not have to take the provocative form of any openly forthright or otherwise official Israeli policy pronouncements. Instead, it could be allowed to “leak” or “spill out” on its own, thereby making a crucial security point without precipitating an immediate crisis or irremediable misfortune.

               Among other things, formal Israeli doctrine would represent the working framework from which a more gainfully pragmatic security posture of selective nuclear disclosure could be extrapolated. In all military institutions and traditions, such doctrine should describe the tactical or operational manner in which designated national forces could fight in variously plausible combat situations; the prescribed “order of battle;” and all manner of corollary or contingent operations. Appropriately, the literal definition of “doctrine” derives from Middle English, from the Latin doctrina, which means teaching, learning and instruction.

               There is more. The central importance of codified Israeli military doctrine lies not only in the particular way it could animate, unify and optimize national military forces, but also in the expectedly efficient manner it could transmit desired “messages” to enemy state Iran, enemy sub-state proxies[16] or state-sub-state “hybrids.[17] Understood in terms of Israel’s strategic nuclear policy, any indiscriminate, across-the-board ambiguity could prove net-injurious to the country’s national security. Though plausibly counter-intuitive, this understanding is likely because any truly effective Israeli deterrence and defense could call for a military doctrine that is at least partially recognizable by Iran and by such sub-state terrorist foes as Hamas or Hezbollah.

               In any routine military planning, having available options for strategic surprise could prove helpful (if not actually prerequisite) to successful combat operations. But successful nuclear deterrenceis another matter entirely. In order to persuade would-be adversaries not to strike first – in these circumstances a manifestly complex effort of dissuasionprojecting too much secrecy could on occasion prove manifestly counter-productive.

               In the matter of Israel and potentially existential enemy Iran, any tangible military success must lie in credible deterrence, not in tangible war-fighting.[18] Examined in terms of ancient Chinese military thought offered by Sun-Tzu in The Art of War, “Supreme excellence consists of breaking the enemy’s resistance without fighting.” With this worthy dictum in mind, there are times for Israel when successful nuclear deterrence policies could require the deliberate “loosening” of information that had formerly been tightly held. Such information would concern Israel’scapabilities, its intentions or both of these core qualities together.

                Sometimes, strategic truth must be counterintuitive. There are, after all, foreseeable circumstances wherein ordinary secrecy could be too much secrecy, and thereby undermine Israel’s national security. We may recall, in this connection, a popular Cold War I-era movie in which Dr. Strangelove, an “eccentric” strategic advisor to the American president (and name of the film itself) discovers, to his horror, that the existence of America’s “doomsday machine” had not been made known in advance to the Soviets: “The whole point of the doomsday machine is lost,” complains Dr. Strangelove, “if you keep it a secret.”

               To have been suitably deterred, the film instructs, and not too subtly, the Soviets ought to have first been given sufficiently prior warnings of the “doomsday machine.” This device had been designed to ensure the perceived automaticity of America’s nuclear retaliatory response. Remembering the commonly-held strategic posture then known as MAD, this response would have been instantly recognizable to the Kremlin as “massive” and “assuredly destructive.”

               It follows from all this and from the more general expectations of the laws of war that Israel’s nuclear weapons should remain oriented to deterrence ex ante, not war fighting or revenge ex post. As designated instruments of a law-based system of deterrence, nuclear weapons can succeed only in their protracted non-use. Once they have been employed for any tangible “battle,” deterrence, by definition, will have failed.[19] Also worth noting, once such weapons are actually used, any traditional meanings of “victory,” especially if both sides are already nuclear, would instantly become moot.[20]

                Cold War I is over, and Israel’s emerging deterrence relationship to a prospectively nuclear Iran is not reasonably analogous or directly comparable to the historic American-Soviet “balance-of-terror.”[21] Still, there are crucial elements of Cold War II superpower antagonisms that will necessarily and substantially impact Israel’s nuclear strategic choices concerning Iran. This means, inter alia, that Israel should never construct its nuclear strategic doctrine and policy apart from close assessments of US-Russia-China relations.[22]

               There are certain Cold War I deterrence lessons to be learned and adapted by Israel during Cold War II. Any unmodified continuance of total nuclear ambiguity concerning Israel’s (a) strategic targeting doctrine; (b) secure basing modes; and/or (c) capacity to penetrate a designated enemy’s active air defenses, could cause a steadily-nuclearizing Iran to underestimate Israel’s retaliatory capacity or resolve. In this connection, Israel should understand that (1) even an Iranian enemy not yet authentically nuclear (i.e., not yet able to combine rockets or missiles with chain-reaction nuclear explosives) could threaten massive attacks against large cities; and (2) even an Iranian enemy still limited in nuclear ordnance to radiation dispersal weapons could be deterred by Israeli nuclear threats. These Israeli threats would likely benefit from (3) visibly antecedent shifts from deliberate nuclear ambiguity to selective nuclear disclosure; and (4) more-or-less coinciding revelations about a “Samson Option.” This residual option, it would have to be made plain, is oriented toward enhanced nuclear deterrence and not to any apocalyptic outcomes drawn from the Biblical Book of Judges.

               The Samson Option’s operational function would be to help Israel “live,” not let it “die with the Philistines.”

               There is more. As a subsidiary but still-urgent nuclear concern, Israeli planners will need to assess the capability and intentions of Pakistan, an already-nuclear Islamic state and one that has already declared a “nuclear war fighting” concept of national nuclear deterrence. Returning to the formative lexicon of Cold War I, this non-Arab Islamic state has undertaken a formal shift from “mutual assured destruction” to “nuclear utilization theory.” In the specialized discourse and parlance of all orthodox nuclear strategic theory, this represents an overt shift from MAD (mutual assured destruction) to NUT (nuclear utilization theory).[23]

               Any such shift, by definition, could have profound legal consequences concerning the presumed likelihood of a nuclear conflict (probability) and the presumed injuriousness of such a conflict (disutility).

               Examined during Cold War II, assorted uncertainties surrounding the presumed components of Israel’s nuclear arsenal could lead enemy states like Iran to reach substantially incorrect conclusions. In part, this is because Israel’s willingness to make good on any threatened nuclear retaliation could then be seen as inversely related to weapon system destructiveness. Ironically, if Israel’s nuclear weapons were sometime believed to be too-destructive,[24] they might not deter. In these cases, such beliefs would underscore basic expectations of humanitarian international law or the law of armed conflict.

                Any continuing Israeli policy of complete nuclear ambiguity could cause an already nuclear enemy state to overestimate the first-strike vulnerability of Israel’s nuclear forces. In part, this overestimation could be the result of a too-complete silence concerning measures of protection that had been deployed to safeguard Israeli nuclear weapons. Such silence, in turn, could be the product of Israel’s perceived alignments with the United States by any relevant regional foe.

               A related problem could represent the product of certain Israeli doctrinal obfuscations regarding the country’s defense potential, a silence that could be mistakenly taken by certain enemy states as an indication of inadequate Israeli Ballistic Missile Defense (BMD). To be maximally useful, certain strengths and capabilities of active defense (interrelated and multi-layered) would need to be revealed, perhaps in previously unimaginable revelations of actual operational detail.

               To best understand the utility and legal content of Israeli strategic nuclear doctrine and posture, analysts should first clarify for themselves the core foundations of Israeli nuclear deterrence. These foundations concern prospective attackers’ perceptions of Israel’s nuclear capability and Jerusalem’s willingness to actually use this capability. Any selective telegraphing of Israel’s strategic nuclear doctrine could potentially enhance Israel’s nuclear deterrence posture. It would accomplish this enhancement by heightening enemy state perceptions of Israel’s capable nuclear forces and by its announced willingness to use these forces in reprisal for certain designated first-strike and/or retaliatory attacks.

               To deter an enemy attack, or a post-preemption retaliation against Israel,[25] Jerusalem must always prevent a rational aggressor, by threat of an unacceptably damaging retaliation or counter-retaliation, from deciding to strike. Here, Israel’s national security would be sought by convincing the potential rational attacker (irrational state enemies could pose an altogether different and possibly insurmountable problem) that the costs of any considered attack will always exceed the expected benefits. Assuming that Israel’s principal state enemy Iran: (1) values self-preservation most highly; and (2) chooses rationally between all alternative options, Tehran will refrain from any attack on an Israel that is believed willing and able to deliver an unacceptably destructive response. It is in circumstances of this sort that Israeli nuclear weapons and doctrine would benefit from selective kinds of disclosure,  

               Iran could also be deterred by the plausible prospect of a more limited Israeli attack, one that would be directed only at the Islamic Republic’s national leaders. In the usual parlance adopted by military and intelligence communities, this particular prospect would refer to more-or-less credible threats of “regime targeting.” Whether credible or incredible, such threats could prove severely problematic in legal terms.[26]

               Two factors must combine to communicate such potentially essential belief. First, in terms of capability, there are two critical components: payload and delivery system. It must be successfully communicated to any calculating Iranian attacker that Israel’s firepower and its available means of delivering that firepower are invariably capable of inflicting unacceptable levels of destruction. This means that Israel’s retaliatory or counter-retaliatory forces must always appear sufficiently invulnerable to enemy first-strikes and sufficiently elusive to penetrate the prospective attacker’s active and civil defenses.

               It may or may not need to be communicated to a potential attacker like Iran that such firepower and delivery vehicles are in any way superior. Deterrence, Israel’s planners should continuously bear in mind, is never about “victory.” The capacity to deter may or may not be as great as the capacity to “win.”[27] In the Israel-Iran matters at hand, “winning” is never a reasonable goal.

               In this connection, Israeli planners could think about North Korea and the United States. In this problematic dyad of international adversaries, the Americans are clearly superior to North Korea in all usual expressions of battle-readiness, but the North Koreans could still bring formidable harms to US armed forces and even to American civilian populations. Moreover, this is to say nothing about parallel or corollary damages that could be visited upon US allies in South Korea or Japan by Kim Jung Un.

               With Israel’s strategic nuclear forces and doctrine kept locked in the “basement,” enemy state Iran could sometime conclude, rightly or wrongly, that a first-strike attack or post-preemption reprisal would be cost-effective. But if relevant Israeli doctrine were made more obvious to Iran – obvious in that Israel’s nuclear assets seemingly met both payload and delivery system objectives – Israel’s nuclear forces could much better serve their indispensable security functions.

               The second factor of nuclear doctrine for Israel concerns willingness. How may Israel convince any potential Iranian attacker that it possesses the resolve to deliver an appropriately destructive retaliation and/or counter retaliation? Again, the answer to this question lies largely in doctrine, that is, in Israel’s demonstrated strength of commitment to actually carry out such an attack and in the “usable” nuclear ordnance that would be made available to its armed forces.

               Here, too, continued ambiguity over nuclear doctrine could wrongfully create the impression of an unwilling Israel. Conversely, any doctrinal movement toward some as-yet-undetermined level of disclosure could meaningfully heighten the impression that Israel was in fact willing to follow-through on its now explicit nuclear threats.

               There are determinably persuasive connections between any incrementally more “open” or disclosed Israeli strategic nuclear doctrine and Iranian perceptions of Israeli nuclear deterrence. One such connection centers on the expected relationship between prospectively greater openness and the perceived vulnerability of Israeli strategic nuclear forces to preemptive destruction. Another such connection concerns the relation between greater openness and the perceived capacity of Israel’s nuclear forces to reliably penetrate the Islamic Republic’s active defenses.

               To be deterred by Israel, a newly-nuclear Iran[28] or any other newly-nuclear adversary would need to believe that at least a critical number of Israel’s retaliatory forces could successfully survive enemy first-strikes and that these forces could not be stopped from hitting pre-designated targets in Iran or elsewhere. Regarding the “presumed survivability” component of such adversarial belief, continued or enhanced sea-basing (submarines) by Israel could prove a clarifying case in point.

               Carefully articulated, an expanding doctrinal openness or partial nuclear disclosure would represent a rational option for Israel, at least to the extent that front-line enemy states such as Iran were made appropriately aware of Israel’s comprehensive nuclear capabilities. The presumed operational benefits of any such expanding doctrinal openness would accrue from certain deliberate flows of information about assorted matters of dispersion, multiplication and hardening of strategic nuclear weapon systems and certain other technical features of these systems. Most important, doctrinally controlled and orderly flows of information could serve to remove any lingering enemy state doubts about Israel’s strategic nuclear force capabilities and intentions. Left unchallenged, such doubts could literally and lethally undermine Israeli nuclear deterrence and, correspondingly, certain war-avoiding expectations of international law.

               A key problem in refining Israeli strategic nuclear policy on deliberate ambiguity issues has to do with what Prussian military thinker Carl von Clausewitz famously calls “friction.” No military doctrine can ever fully anticipate the actual pace of combat activity, or, as a corollary, the precise reactions of individual human commanders under fire. It follows that Israel’s nuclear doctrine must be encouraged to combine adequate tactical flexibility with a selective doctrinal openness. To understand exactly how such seemingly contradictory objectives can be reconciled in Jerusalem now presents a primaryintellectual challenge to Israel’s national command authority.[29]

               In the end, Israeli planners must think about paths to nuclear war that include the risks of inadvertent or accidental nuclear war. Though risks of a deliberate nuclear war involving Israel and Iran would be small, the Jewish State could still be vulnerable to a conflict occasioned by a mechanical/electrical/computer malfunction and/or by assorted decisional errors (i.e., miscalculation).

               To properly assess the different but intersecting risks between a deliberate nuclear war and an inadvertent or accidental nuclear war should immediately be regarded as overriding in Jerusalem. These risks, including corollary legal implications, could exist independently of one another and/or could be impacted in various ways by Cold War II alignments. Israel, like the much larger United States, will continuously need to prepare for bewildering scenarios of cyber-attack and cyber-war. Such scenarios will now need to be considered together with the unpredictably destabilizing advent of “digital mercenaries.”

               One more core conceptual distinction warrants prominent mention. This references the difference between inadvertent and accidental nuclear war. By definition, any accidental nuclear war would need to be inadvertent. Conversely, however, an inadvertent nuclear war would not necessarily be accidental. False warnings, for example, which could be generated by various types of technical malfunction or sparked by third-party hacking/digital mercenary interference (which might or might not have something to do with the dynamics of Cold War II) would not be included under the causes of an unintentional or inadvertent nuclear war. Instead, they would represent cautionary narratives of an accidental nuclear war.

               Most critical among the plausible causes of any inadvertent nuclear war would be errors in calculation by one. both or several sides. The most blatant example would involve misjudgments of either enemy intent or enemy capacity that would emerge and propagate as any particular crisis would escalate. Such consequential misjudgments could stem from an understandably amplified desire by one or several parties to achieve “escalation dominance.” During any major crisis between Israel and Iran, it would be the common desire for “escalation dominance” that could prove unmanageable.

               There are applicable nuances. In any such crisis condition, both sides, acting rationally, would strive for calculable advantage without too-unreasonably risking total or near-total destruction. But what would be the operative standards for determining reasonableness? There would still likely be “opportunities” for misunderstanding and miscalculation. Naturally, where the adversaries would no longer be rational, all once-reassuring deterrence “bets” would be “off.”

               Other causes of an inadvertent nuclear war involving Israel and Iran could include flawed interpretations of computer-generated nuclear attack warnings; an unequal willingness between adversaries to risk catastrophic war; overconfidence in deterrence and/or defense capabilities on one or both sides (including Israel); Iranian regime changes; outright revolution or coup d’état in Iran and poorly-conceived pre-delegations of nuclear launch authority by Iran.

               Serious problems of overconfidence could be aggravated by successful tests of a contending nation’s missile defense operations, whether Israel or Iran. These problems could be encouraged by too-optimistic assessments of Cold War II alliance guarantees. An example might be an intra-crisis judgment in Jerusalem that Washington would continuously stand firmly behind Israel’s every crisis move. Reciprocally, Iran could mistake the seriousness and commitment of its own preferred Cold War II guarantor, whether Russian or North Korean. Interestingly, North Korea continues to maintain close ties with both Tehran and Damascus, and could conceivably act as a still pre-nuclear Iran’s nuclear surrogate during intense crises with Israel.

               There is more. A potential source of inadvertent nuclear war during Cold War II could be the “backfire” effect from strategies of “pretended irrationality. A rational Iranian enemy of Israel that had managed to convince Jerusalem of its own decisional irrationality could spark an otherwise avoidable Israeli military preemption. Conversely, an Iranian leadership that had begun to take seriously any hint of decisional irrationality in Jerusalem could sometime be frightened into striking first. Regarding this second scenario, it should be remembered that many years back, General Moshe Dayan, then Israel’s Minister of Defense, argued that “Israel must be seen as a mad dog, too dangerous to bother.”

               Though analytic and science-based, Israeli thinkers and planners are facing an adversarial “nightmare.” According to the etymologists, the root is niht mare or niht maere, the demon of the night. Dr. Johnson’s dictionary says this corresponds to Nordic mythology – which regarded nightmares as the product of demons. This would make it a play on, or a translation of, the Greek ephialtes or the Latin incubus. In all such interpretations of nightmare, the non-rational idea of demonic origin is central.

               But the demons of nuclear strategy and nuclear war would take a very different form. For the most part, their mien is not expressly frightful, but (though often bombastic) “rational.” If Iran’s leaders are thought to be sinister, it is not that quality that should be most strategically or legally worrisome to Israel.  While the state of nations has always been in the “state of nature,”[30] at least since the seventeenth century and the historic Peace of Westphalia (1648), current conditions of nuclear capacity and worldwide anarchy portend a unique amalgam of law-violating circumstances.

               Among other things, the reasons behind such dire portents lie in the indispensability of rational decision-making to operationally viable nuclear deterrence and in the subtly interpenetrating fact that rational decision-making could sometime become subject to corrosive modifications or complete disappearance. Though not readily predictable, such impacts upon Iranian enemy rationality could be derived from the ever-changing dynamics of Cold War II. A future example of what is being described here would be any strategic nuclear decisions in Tehran that are based in whole or in part upon that enemy state’s subjective interpretations of Cold War II.

               With still largely unpredictable enlargements of Cold War II, Israeli decision-makers should systematically prepare for progressively complex scenarios. To manage these challenging scenarios, they will first have to prepare for literally unprecedented levels of world-systemic upheaval and transformation, and, correspondingly, for seemingly unfathomable levels of decisional complexity. In some cases, these decision-maker calculations could have to acknowledge varying levels of Iranian irrationality.

               For Israel, ultimate survival will require durable “victories” of “mind over mind.”[31] In turn, these analytic victories will depend on prior Israeli capacities to more fully understand the many-sided elements of Cold War II. In principle, at least, such prior capacities could lead Israel to consider ambitious preemption options. Final decisions regarding these residual options would be properly based upon (a) expectations of enemy rationality or irrationality; (b) expected likelihood of enemy first-strikes; (c) expected costs or disutilities of enemy first-strikes; (d) expected schedule of enemy nuclear (or biological) weapons deployments; (e) expected efficiencies of enemy active defenses over time; (f) expected efficiencies of Israel’s active defenses over time; (g) expected efficiencies of Israeli hard-target counterforce operations over time; (h) expected reactions of unaffected regional enemies; and (i) expected US, Russian, Chinese and world community reactions to Israeli preemptions.[32]

                Israel’s ultimate “ace-in-the-hole” regarding aggression from Iran is nuclear deterrence and its capacity to achieve “escalation dominance” without eliciting an uncontrollable and potentially nuclear war. This deterrence objective could represent an existential challenge for Israel before the Islamic Republic of Iran became an authentic nuclear power. Even a still pre-nuclear Iran, together with various state and sub-state allies, could push Israel toward the escalatory brink, leaving Jerusalem with just a binary choice between nuclear weapons use and outright capitulation. The only way for Jerusalem to prevent or modify such an intolerable choice would be to upgrade its indispensable nuclear deterrent from the particular standpoints of selective nuclear disclosure and a reinterpreted “Samson Option.”

               Not to be forgotten or overlooked in this existential calculation is Swiss playwright Friedrich Dürrenmatt’s generic warning: “The worst does sometimes happen.”


[1] In any of its conceivable forms, terrorism is a crime under international law.

[2] Taken from Plato’s lexicon of philosophical investigation, dialectic has its root in the Greek verb meaning “to converse,” where the objective of any such conversation is to discover “what each thing actually is.” (Republic.) Speaking through Socrates, it is evident that Plato regards dialectic as the highest or supreme form of knowledge.

[3] Historically, the idea of a balance of power – an idea of which the nuclear-age balance of terror is a current variant – has never really been more than a facile metaphor. In fact, it has never had anything to do with ascertaining any true equilibrium. As such a balance is always a matter of individual and more-or-less subjective perceptions, adversary states can never be sufficiently confident that identifiable strategic circumstances are “balanced” in their favor. In consequence, each side perpetually fears that it will be left behind, and the continual search for balance produces ever wider patterns of insecurity and disequilibrium.

T.S. 119.   This “Westphalian” anarchy stands in stark contrast to the legal assumption of solidarity between all states in the presumably common struggle against aggression and terrorism. Such a peremptory expectation (known formally in international law as a jus cogens assumption), is already mentioned in Justinian, Corpus Juris Civilis (533 C.E.); Hugo Grotius, 2 De Jure Belli Ac Pacis Libri Tres, Ch. 20 (Francis W. Kesey, tr., Clarendon Press, 1925 (1690); and Emmerich De Vattel, 1 Le Droit des Gens, Ch. 19 (1758).

[6] Conspicuous preparations for nuclear war fighting could be conceived not as distinct alternatives to nuclear deterrence, but as essential and even integral components of nuclear deterrence.  Earlier, Colin Gray, reasoning about U.S.-Soviet nuclear relations, argued that a vital connection exists between “likely net prowess in war and the quality of pre-war deterrent effect.”  (See:  Colin Gray, National Style in Strategy: The American Example,” INTERNATIONAL SECURITY, 6, No. 2, fall 1981, p. 35.)  Elsewhere, in a published debate with this writer, Gray said essentially the same thing:  “Fortunately, there is every reason to believe that probable high proficiency in war-waging yields optimum deterrent effect.”  (See Gray, “Presidential Directive 59: Flawed but Useful,” PARAMETERS, 11, No. 1, March 1981, p. 34.  Gray was responding directly to Professor Louis René Beres, “Presidential Directive 59: A Critical Assessment,” PARAMETERS, March 1981, pp. 19 – 28.).

[7] Reciprocally, almost by definition, it could have an opposite effect upon the adversarial state or terror group.

[8] One core issue here would concern Israeli reliance upon a steadily weakening US for “extended deterrence.” Going forward, Israel could sometime find itself lined up more closely on certain issues with Moscow than with Washington. See, on such ironic but conceivable prospects: Louis René Beres, “Staying Strong: Enhancing Israel’s Essential Strategic Options,” Harvard National Security Journal, Harvard Law School, June 13, 2014.

[9] Expressions of decisional irrationality could take different and overlapping forms. These forms include a disorderly or inconsistent value system; computational errors in calculation; an incapacity to communicate efficiently; random or haphazard influences in the making or transmittal of particular decisions; and the internal dissonance generated by any structure of collective decision-making (i.e., assemblies of pertinent individuals who lack identical value systems and/or whose organizational arrangements impact their willing capacity to act as a single or unitary national decision maker).

[10] For the specific crime of aggression under international law, see: Resolution on the Definition of Aggression, adopted by the U.N. General Assembly, Dec. 14, 1974, U.N.G.A. Res. 3314 (xxix), 29 U.N. GAOR, Supp. (No. 31), 142, U.N. Doc. A/9631 (1975), reprinted in 13 I.L.M., 710 (1974).

[12] A great deal has been written on pertinent questions of “strategic depth.”  The heart of this issue was addressed as early as June 29, 1967, when a U.S. Joint Chiefs of Staff memorandum specified that returning Israel to pre-1967 boundaries would drastically increase its vulnerability.  The then Chairman of the JCS, General Earl Wheeler, concluded that for minimal deterrence and defense, Israel must retain Sharm el Sheikh and Wadi El Girali in the Sinai; the entire Gaza Strip; the high ground and plateaus of the mountains in Judea and Samaria; and the Golan Heights, east of Quneitra. 

[13] The writer, Professor Louis René Beres, is author of one of the earliest books on this theme, Security of Armageddon: Israel’s Nuclear Strategy (Lexington Books; 1986).

[14]This permissible option can be found not in the conventional law (art. 51 of the UN Charter supports only post-attack expressions of individual or collective self-defense), but in customary international law. The precise origins of anticipatory self-defense in such customary law lie in the Caroline, a case that concerned the unsuccessful rebellion of 1837 in Upper Canada against British rule. Following this case, the serious threat of armed attack has generally justified certain militarily defensive actions. In an exchange of diplomatic notes between the governments of the United States and Great Britain, then U.S. Secretary of State Daniel Webster outlined a framework for self-defense that did not require an antecedent attack. Here, the jurisprudential framework permitted a military response to a threat so long as the danger posed was “instant, overwhelming, leaving no choice of means, and no moment for deliberation.” See: Beth M. Polebaum, “National Self-defense in International Law: An Emerging Standard for a Nuclear Age,” 59 N.Y.U.L. Rev. 187, 190-91 (1984) (noting that the Caroline case had transformed the right of self-defense from an excuse for armed intervention into a legal doctrine). Still earlier, see: Hugo Grotius, Of the Causes of War, and First of Self-Defense, and Defense of Our Property, reprinted in 2 Classics of International Law, 168-75 (Carnegie Endowment Trust, 1925) (1625); and Emmerich de Vattel, The Right of Self-Protection and the Effects of the Sovereignty and Independence of Nations, reprinted in 3 Classics of International Law, 130 (Carnegie Endowment Trust, 1916) (1758). Also, Samuel Pufendorf, The Two Books on the Duty of Man and Citizen According to Natural Law, 32 (Frank Gardner Moore., tr., 1927 (1682).

[15] The actual security benefits to Israel of any explicit reductions in nuclear secrecy would remain dependent, more or less, upon Clausewitzian “friction.” This refers to the inherently unpredictable effects of errors in knowledge and information concerning intra-Israel (IDF/MOD) strategic uncertainties; on Israeli and Iranian under-estimations or over-estimations of relative power position; and on the unalterably vast and largely irremediable differences between theories of deterrence, and enemy intent “as it actually is.” See: Carl von Clausewitz, “Uber das Leben und den Charakter von Scharnhorst,” Historisch-politische Zeitschrift, 1 (1832); cited in Barry D. Watts, Clausewitzian Friction and Future War, McNair Paper No. 52, October, 1996, Institute for National Strategic Studies, National Defense University Washington, D.C. p. 9.

[16] Explicit applications of the law of war to insurgent combatants’ dates to the four Geneva Conventions of 1949. As more than codified treaties and conventions must comprise the law of war, the obligations of jus in bello (justice in war) are part of “the general principles of law recognized by civilized nations” (from Art. 38 of the Statute of the International Court of Justice) and thereby bind all categories of belligerents. (See Statute of the International Court of Justice, art. 38, June 29, 1945, 59 Stat. 1031, T.S. 993).  Further, Hague Convention IV of 1907 declares that even in the absence of a precisely published set of guidelines regarding “unforeseen cases,” the operative pre-conventional sources of humanitarian international law obtain and still govern all belligerency. The related Martens Clause is included in the Preamble of the 1899 Hague Conventions, International Convention with Respect to the Laws and Customs of War by Land, July 29, 1899, 187 Consol. T.S. 429, 430.

The best current example here for Israel is the Iran –Israel hybrid.

[18] This was a major conclusion of this author’s Project Daniel Report (2003) to then Prime Minister Sharon. It was titled Israel’s Strategic Future. http://www.acpr.org.il/ENGLISH-NATIV/03-ISSUE/daniel-3.htm

[19] There could also be attendant and possibly unprecedented crimes of war. Moreover, criminal responsibility of leaders under international law is not limited to direct personal action or limited by official position. On this peremptory principle of “command responsibility,” or respondeat superior, see: In re Yamashita, 327 U.S. 1 (1945); The High Command Case (The Trial of Wilhelm von Leeb), 12 Law Reports of Trials Of War Criminals 1 (United Nations War Crimes Commission Comp., 1949); see Parks, Command Responsibility For War Crimes, 62 MIL.L. REV. 1 (1973); O’Brien, The Law Of War, Command Responsibility And Vietnam, 60 GEO. L.J. 605 (1972); U.S. Dept. Of The Army, Army Subject Schedule No. 27 – 1 (Geneva Conventions of 1949 and Hague Convention No. IV of 1907), 10 (1970). The direct individual responsibility of leaders is also unambiguous in view of the London Agreement, which denies defendants the protection of the act of state defense. See AGREEMENT FOR THE PROSECUTION AND PUNISHMENT OF THE MAJOR WAR CRIMINALS OF THE EUROPEAN AXIS, Aug. 8, 1945, 59 Stat. 1544, E.A.S. No. 472, 82 U.N.T.S. 279, art. 7.

[21] Recalling the Roman Stoic philosopher and statesman, Cicero, in The Letters to His Friends: “For what can be done against force, without force?” During the nuclear age, the traditional term, “balance of power” has sometimes been replaced with a more technologically appropriate “balance of terror.” For the conceptual origins of this historic replacement, see Albert Wohlstetter, “The Delicate Balance of Terror,” Foreign Affairs, Vol. 37, No.2., January 1959, pp. 211-234.

[22] In this connection, Jerusalem must always ensure that it does not enter into any legal agreements that might threaten its overall physical survival. Thomas Jefferson, third president of the United States, wrote about this core obligation as generic for all nations. Writing in his Opinion on the French Treaties (April 28, 1793), Jefferson opined: “The nation itself, bound necessarily to whatever it’s preservation and safety require, cannot enter into engagements contrary to its indispensable obligations.” See: Merrill D. Peterson, The Political Writings of Thomas Jefferson, Monticello Monograph Series, Thomas Jefferson Memorial Foundation, 1993, p. 115.

[23] Several of this author’s earlier books deal expressly with the pertinent distinctions. See, for example, by Louis René Beres: The Management of World Power: A Theoretical Analysis; Apocalypse: Nuclear Catastrophe in World Politics; Reason and Realpolitik: US Foreign Policy and World Order; Mimicking Sisyphus: America’s Countervailing Nuclear Strategy; Security or Armageddon: Israel’s Nuclear Strategy; and Israel’s Nuclear Strategy and US National Security (Tel Aviv), a 2016 monograph co-authored by Professor Beres and General (USA/ret.) Barry McCaffrey.

[24] The underlying idea here of some palpable apocalypse seems to have been born in ancient Iran (Persia), specifically, with the Manichaeism of the Zoroastrians. Interestingly, at least one of these documents, The War of the Sons of Light Against the Sons of Darkness, found in a Qumran cave, is a comprehensive description of Jewish military tactics and regulations at the end of the Second Commonwealth. In essence, the “Sons of Light” were expected to prevail in battle against the “Sons of Darkness” before the “end of days,” and the later fight at Masada was widely interpreted as an apocalyptic struggle between a saintly few and the wicked many.

[25] Regarding preemption, the obvious Israeli precedents for any such defensive moves would be Operation Opera directed against the Osiraq (Iraqi) nuclear reactor on June 7, 1981, and, later (though lesser known) Operation Orchard against Syria on September 6, 2007. In April 2011, the U.N.’s International Atomic Energy Agency (IAEA) confirmed that he bombed Syrian site in the Deir ez-Zoe region of Syria had indeed been a developing nuclear reactor. In this writer’s judgment, both preemptions were lawful assertions of Israel’s “Begin Doctrine.”

[26] Such legal difficulties could bring up the authoritative “Nuremberg Principles.”  In this connection, the principles of international law recognized by the Charter of the Nuremberg Tribunal and the judgment of the Tribunal were affirmed by the U.N. General Assembly as AFFIRMATION OF THE PRINCIPLES OF INTERNATIONAL LAW RECOGNIZED BY THE CHARTER OF THE NUREMBERG TRIBUNAL.  Adopted by the U.N. General Assembly, Dec. 11, 1946.  U.N.G.A. Res. 95 (I), U.N. Doc. A/236 (1946), at 1144.  This AFFIRMATION OF THE PRINCIPLES OF INTERNATIONAL LAW RECOGNIZED BY THE CHARTER OF THE NUREMBERG TRIBUNAL (1946) was followed by General Assembly Resolution 177 (II), adopted November 21, 1947, directing the U.N. International Law Commission to “(a) Formulate the principles of international law recognized in the Charter of the Nuremberg Tribunal and in the judgment of the Tribunal, and (b) Prepare a draft code of offenses against the peace and security of mankind….” (See U.N. Doc. A/519, p. 112).  The principles formulated are known as the PRINCIPLES OF INTERNATIONAL LAW RECOGNIZED IN THE CHARTER AND JUDGMENT OF THE NUREMBERG TRIBUNAL.  Report of the International Law Commission, 2nd session, 1950, U.N. G.A.O.R. 5th session, Supp. No. 12, A/1316, p. 11.

[29] “It must not be forgotten,” writes French poet Guillaume Apollinaire in “The New Spirit and the Poets” (1917), “that it is perhaps more dangerous for a nation to allow itself to be conquered intellectually than by arms.”

[30] Says Thomas Hobbes: “But though there had never been any time wherein particular men were in a condition of war one against another, yet in all times, Kings and Persons of Sovereign Authority, because of their Independency, are in continual jealousies, and in the state and posture of Gladiators, having their weapons pointing and their eyes fixed on one another…(Leviathan).
