Suspended Between Escalation and Exit: The U.S.–Iran War’s Strategic Deadlock

From Tehran to Riyadh, from Muscat to Shanghai, the campaign looks less like a coherent plan than a display of force untethered from a clear endgame.

Entering the second month of the war with Iran, the United States has delivered substantial military effects without articulating a viable political end state—a familiar pattern in which battlefield success fails to produce strategic clarity and increasingly risks an exit without resolution.

Washington has degraded key elements of Iran’s military capacity, yet what “victory” entails — and whether the United States intends to see the conflict through to a stable outcome — remains undefined. By mid-March, U.S. and Israeli forces had established broad air superiority, striking missile launchers, storage sites, naval assets, and command infrastructure.

On March 20, President Donald Trump declared on Truth Social that the “fight is militarily WON.” Yet the war grinds on, underscoring the gap between operational success and strategic purpose. From Tehran to Riyadh, from Muscat to Shanghai, the campaign looks less like a coherent plan than a display of force untethered from a clear endgame.

That disconnect is most visible in the Strait of Hormuz.

Hormuz: the strait that swallowed the strategy

The Strait of Hormuz now sits at the center of the war’s strategic dilemma. U.S. officials can insist the waterway remains “physically open,” but that distinction means little when commercial shipping is deterred by the threat of missiles, drones, and mines. For shipowners, insurers, and Asian refiners, a strait under persistent threat is functionally closed—insurance withdrawal is doing the work that a physical blockade has not, with outcomes for cargo flow that are largely the same.

That reality has carried immediate global consequences. Tanker traffic has nearly halted. Insurance costs have surged, and oil prices have swung violently with every new signal of escalation or de-escalation. Fatih Birol, the executive director of the International Energy Agency (IEA), called the disruption worse than the combined oil crises of 1973 and 1979, warning that no country would be immune to its effects.

That helps explain why Trump’s 48-hour ultimatum vowing to “hit and obliterate” Iran’s power plants unless it reopens the strait was so reckless. The threat carried an obvious humanitarian cost, as civilians bear the brunt of attacks on essential infrastructure. But it also carried a strategic cost. Tehran fired back that any strike on its energy infrastructure would mean a full closure of Hormuz and possible attacks on energy and desalination facilities in U.S.-aligned Gulf states, deepening the crisis Washington claimed it wanted to solve.

Hours before his deadline expired, Trump extended it for another 10 days, citing ongoing talks, yet kept the threat alive in subsequent remarks.

Far from creating leverage, the threat exposed a deeper problem. Washington could escalate, but the core artery of global oil trade had swallowed its strategy.

That disconnect was further underscored when Trump suggested in his April 1 address that the United States had already achieved its primary objective of neutralizing Iran’s nuclear program and that the conflict could end within “two or three weeks.” He paired that claim with assurances that gasoline prices would soon fall once the war concluded, while casting the effective closure of the Strait of Hormuz and the disruption of global energy flows as a problem for others to manage. The juxtaposition was stark, with the war framed as nearing resolution even as its defining strategic and economic shock remained unresolved.

At the same time, Trump continued to press Iran to negotiate an end to the war while offering little clarity on what such a deal would entail, even as he insisted the tempo of U.S. strikes would not slow. He further downplayed concerns about Iran’s buried enriched uranium stockpile—undercutting a central rationale for the war—while pairing renewed threats of escalation with claims that the United States would not take responsibility for securing the very waterway at the heart of the conflict.

Trump’s sudden framing of the war as nearly complete constitutes an ironic climbdown, especially given his earlier insistence on Iran’s unconditional surrender. Yet in doing so, the U.S. has gained little in terms of eliminating the nuclear threat, while likely reinforcing Tehran’s incentives to preserve and potentially accelerate its program.

More broadly, the shift reflects a pattern in which, as objectives have blurred, responsibility has increasingly been displaced onto allies in the present and deferred to successors in the future.

The fog of diplomacy

Iran, by contrast, appears to be pursuing a more calibrated diplomatic approach, one that exploits this disconnect. Its selective reopening of the strait fits a strategy of controlled de-escalation, maintaining leverage while rewarding aligned states and conditioning full access on political concessions. The accompanying demands for reparations and sovereignty serve as a high anchor, creating space to concede while sustaining an image of resolve.

That contrast was immediately visible on March 23, when Trump posted on Truth Social that the U.S. and Iran had held “very good and productive conversations” toward a “complete and total resolution” of the conflict. Markets responded instantly—the Dow surged over 1,000 points, and Brent crude fell close to 11 percent. But Tehran publicly denied that any direct or indirect talks with Washington had taken place. The result was immediate confusion over whether diplomacy was real or simply another market-moving signal from the White House.

The interlocutor on the Iranian side was said to be parliament speaker Mohammad Bagher Qalibaf — though Trump declined to name him, saying he didn’t want to get him killed. Behind the scenes, a different picture appeared to be taking shape, with the foreign ministers of Egypt, Turkey, Pakistan, and Saudi Arabia gathering in Riyadh and apparently opening a back channel to Iran, potentially giving Trump an opening to pivot toward diplomacy amid mounting political and economic fallout.

CNN reported that “none of the proposals discussed have reached a stage of maturing or general acceptance,” with a source cautioning that diplomacy remained “a free-flowing discussion.” China’s special envoy for the Middle East, Zhai Jun, upon returning from the region, delivered Beijing’s terse verdict on responsibility at a Beijing briefing: “The one who tied the bell must be the one to untie it,” a pointed reminder that the parties that launched the war—above all, the United States and Israel—bear primary responsibility for ending it.

Taken together, these episodes reveal how little trust remains. The Trump administration offered various and conflicting explanations for starting the war—ranging from warding off an imminent Iranian threat, to preempting retaliation, to destroying Iran’s missile capabilities, to preventing nuclear weapons development, to securing Iran’s natural resources, to achieving regime change. Those are not variations on the same goal. They imply different wars, different levels of commitment, and different terms for ending the conflict.

From Tehran’s perspective, that incoherence is not just confusing—it is dangerous. A ceasefire offer can easily be read as a pause to calm oil markets, regroup militarily, or reset diplomatic optics while the war continues by other means. Iran has ample reason to view American improvisation not as flexibility but as a trap.

Two wars, two definitions of victory

The deeper problem is asymmetry—not of military power, but of political objectives.

One week into the war, the U.S. appeared to have settled on four primary objectives: destroying Iran’s navy, degrading its missile capabilities, preventing nuclear weapons development, and ending Iranian support for proxy groups. Those ambitions may be individually intelligible, but together they do not add up to a coherent settlement. Without clarity of purpose, aligning ways and means is nearly impossible.

To be sure, wartime objectives are rarely static. They are often implicit, contested, and subject to revision as conditions change. But what is striking here is not that U.S. aims have evolved. It is that they pull in different directions, ranging from limited military degradation to regime change, without a clear hierarchy or connection to a coherent political end state.

This is a lesson Washington has repeatedly failed to absorb. Iraq, Afghanistan, and Libya were different wars, but they shared one fatal pattern: military action ran ahead of political definition, and tactical success created the illusion of strategic clarity where none existed. The pattern persists, despite assurances that “this is not Iraq” and indications from Trump that he would not rule out deeper military involvement.

Iran’s objectives are narrower and therefore easier to meet. Tehran does not need to defeat the United States militarily. It needs to survive, preserve regime control, and retain enough coercive capacity to show that a far stronger coalition could not impose its preferred outcome.

The war may not restore broad legitimacy to the clerical order, but it could help the regime consolidate control in the near term. External attack has historically redirected public anger outward and constrained open dissent. Even among those alienated from the regime, the war may deepen resentment toward the United States.

That gives Tehran an advantage Washington lacks, for it only needs to show it survived, while the U.S. must demonstrate that the war produced a new strategic reality.

Even a limited residual ability to strike shipping, oil infrastructure, or symbolic targets gives Tehran leverage far beyond the scale of the attacks themselves. One successful hit in or around the Gulf can move prices, raise insurance premiums, unsettle allied governments, and reinforce the perception that Washington has not restored control over the theater.

This is why maximal tactical success may still fail to produce decisive political victory. The weaker actor’s threshold for success is structurally lower.

No clean exit through escalation

If diplomacy fails, the military options only grow worse.

U.S. options hinge on objectives but offer no clean solution. Seizing Iran’s enriched uranium at sites like Isfahan and Natanz would be operationally difficult and insufficient to eliminate long-term proliferation risk. Targeting Kharg Island could choke off oil revenue but escalate economic warfare. Forcing Hormuz open would require suppressing mainland missile threats, an uncertain prospect. Diplomacy remains possible but unpromising, with maximalist demands on both sides. None resolves the core problem. Iran retains escalation leverage and few incentives to concede.

As former Defense Secretary James Mattis put it at CERAWeek, the U.S. is “in a tough spot” with few good options. Even as the arrival of U.S. forces fueled expectations of possible offensive operations, Trump pressed others to take responsibility for securing the strait, rebuking European allies and telling them to “get your own oil.” The juxtaposition reinforced perceptions of strategic incoherence — at best, a pattern of conflicting signals about U.S. objectives.

In that context, escalation does not clarify strategy; it compounds risk. A more ambitious effort to seize or destroy the remainder of Iran’s nuclear material would be especially perilous. It would require intelligence that may not exist, operations against dispersed and hardened sites, and a level of sustained military involvement that the United States has little appetite for.

None of these options offers a clean exit. Tactical gains can only go so far when they are not tied to a defined strategy and clear political objectives. That is the core problem Washington still has not solved.

Conclusion

The United States has inflicted serious damage on Iran, but not enough to end the war on its own terms. Iran, for its part, has absorbed heavy punishment while retaining the ability to impose meaningful costs. The conflict persists because the two sides are operating with different definitions of victory—and because Washington, despite its overwhelming military superiority, still has no coherent political answer to how this ends.

The war’s defining feature is not American strength but strategic indeterminacy. Four weeks in, Washington has shown neither how to reopen Hormuz without leaving Tehran with leverage nor how to convert battlefield gains into a stable political outcome. Even as the conflict is at times framed as nearing resolution, key threats — including Iran’s nuclear program — remain largely intact, and the incentives for Tehran to safeguard or accelerate that program have only increased.

The most realistic goal may no longer be victory, but damage limitation to U.S. interests, regional stability, and civilians across the Middle East.

The war remains suspended between escalation and exit, with no credible endgame in sight. That is not strategy. It is an attempted exit that leaves the conflict’s central strategic problem unresolved and shifts responsibility to allies and successors.
