Why shouldn’t Israel Undermine Iran’s Conventional Deterrence

When Naftali Bennett took over as the prime minister of Israel, it was expected that he would take a different approach compared to Netanyahu. This could be a probable expectation, save for the issue of Iran, since Iran is considered a consistent strategic and existential threat in the eyes of Israeli political and military officials same way that Israel has always been considered an enemy in the strategic culture of the Islamic Republic of Iran. Therefore, with the resumption of the Iran nuclear talks in Vienna, Israel has intensified its campaign for an imminent military strike on Iran. On the other hand, Iran has tried to create a balance of missile threat against Israel based on valid deterrence during the past years.

However, the level and the nature of performance and deterrence of these two influential actors of the Middle East are fundamentally different. While Iran has defined its deterrence based on hybrid missile deterrence concepts—including direct and extended deterrence—, Israel’s deterrence is based on preemptive warfare, a.k.a. “immediate deterrence,” irrespective of its nuclear capabilities, policies of “strategic ambiguity” and “defensible borders strategy.”

From a direct deterrence perspective (i.e., the strength of a large missile fire from within Iranian territory) and given the extended and asymmetric dimensions (i.e., strengthening missile capabilities of the axis of resistance), the Islamic Republic of Iran believes that Israel will gradually become weaker and more fragile defensively, considering the importance of objective components in the area of ​​deterrence—such as geographical depth and population, and this will derive Israeli leaders to consider their fragile security and survival before any attempt to take on a direct military confrontation with Iran. For instance, when the tensions over Iran’s nuclear program escalated between 2010 and 2013 during the Obama administration, none of Iran’s nuclear facilities was attacked, despite Israel’s repeated expression of its willingness to do so. Former defense minister Ehud Barak justified this inaction with the pretext of Barack Obama’s opposition and lack of support.  In fact, the Netanyahu administration sought to instill this idea to the world that Israel has both the “determination” and the “ability” to attack Iran should this preemptive action not have been faced with Washington objection. The fact that Netanyahu still failed to implement the idea even during Trump administration—as John Bolton points out in the first chapter of his book—despite his overwhelming support for Israel, indicated the fact that Israel does not have independent military capabilities and determination to take such hostile action at no cost without the support of the US.

Therefore, despite the constant claims of Israeli officials, this country’s general strategy so far has been to avoid direct military confrontation with Iran and to focus on less intense and covert warfare. This has changed since 2017 due to Israel’s objection to pro-Iranian forces regaining the control over Al-Bukamal Qa’im border crossing on the Iraqi-Syrian border, and the consequent lack of a proportionate and retaliatory response from Iran to Israel’s ongoing operations in Syria. In fact, inaction of Iran has allowed Israeli army to expand its campaign from northern borders and the Golan Heights (as the first ring) to the province of Deir ez-Zor in eastern Syria, then to the depths of Iraq in cooperation with the US (as the second ring), and eventually, inside the Iranian territory (as the third ring). The expansion of Israel’s subversive actions deep inside Iran is an effort to discredit Iran’s deterrence as well as undermining Iran’s strategic stability, while also dismantling Iran’s military and nuclear capabilities.

In the meantime, Israel’s embark on the strategy of Third-Circle Directorate based on intensifying low-level but effective military actions on Iranian soil has played a greater role in undermining Iran’s conventional deterrent advantages. Israel’s repeated operation and its recklessness in accepting responsibility for such actions has taken Israel’s belief and determination that it can target Iran’s assets and strategic resources inside and outside of Iran with numerous intermittent actions to a new level. Therefore, it can be said that while the previous positions of Israeli officials regarding the bombing and cessation of Iran’s nuclear capabilities were mostly focused on the assassination of Iranian scientists, targeted cyberattacks, sabotages, and bombings of industrial, security, and military facilities, there is no guarantee that the Third-Circle Directorate would not extent to explicit and direct entry of Israeli fighters, bombers or ballistic missiles to bomb Iran’s nuclear and military facilities in cooperation with the United States or independently.

If Israel mistakes Iran’s inaction with inability to respond and decides to extend Mabam Campaign to air or missile strikes inside the Iranian borders, it should not be sure of the unpredictable consequences. Iran has not yet responded decisively to cyber-attacks, the assassination of its scientists, and the Israeli sabotages due to the fact that these actions have been designed and carried out in such a way that Iran has assessed the damage as compensable. That is, a long set of low-level attacks were conducted to change the state of the field without taking actions that justifies an extensive reaction. Iran’s failure to respond to the recent Israeli attack on the port of Latakia is a clear example of the success and effectiveness of Salami Slicing strategy. Such strategies are designed to engage Iran in a polygonal dilemma: that it cannot respond to every individual military actions and small-scale sabotage, while inaction against these multiple small and non-intensive attacks will gradually result in losing its strategic position and deterrent credibility.

This very, unique Israeli strategy in military confrontation with Iran has reinforced the assessment of the Bennett administration about the serious weakness of Iran’s conventional deterrence. As a clear case Foreign Minister Yair Lapid claimed that “Israel could attack Iran if necessary without informing the Biden administration, which is looking to rejoin the nuclear deal”. This problem became more apparent after the assassination of the commander of the Quds Force of the IRGC, especially in the last months of Donald Trump’s presidency. In other words, if Tehran decided to respond directly to various Israeli actions, such as the assassination of Mohsen Fakhrizadeh and attacks on its military and industrial centers, the risk of a war with Israel with the support of the US would increase. By the same token, this has in fact given Tehran an opportunity not to retaliate based on the concept of conventional strategic stability. That is, at this level of conflict, Iran’s confidence in its ability to retaliate makes it easier for this country to limit and delay the response. From Iranian perspective, therefore, conventional strategic stability means preventing armed conflict in the Middle East, especially a level of conflict that directly threatens its security and territory.

However, if Israel tries to discredit Iran’s conventional deterrence and strategic stability by launching a direct air strike into Iranian territory, Iran’s retaliatory response will not be as limited and symbolic as the attack on the US base of Ain al-Assad in Iraq, because Tehran would face the so-called “Sputnik moment” dilemma, which forces it to test its missile credibility. In such a situation, Iran will be forced to first, launch a decisive comprehensive missile response against Israel and then change its deterrent structure from conventional to nuclear by leaving the NPT in order to contain pressure of domestic public opinion, maintain its credibility with regional rivals such as Turkey, Pakistan, Saudi Arabia, and even the Republic of Azerbaijan, and to reassure its proxy forces in the axis of resistance.
