Caught in its Own Doctrine: Why Israel Cannot Win, Stop, or Endure the Iran War
Introduction
Israel’s war with Iran was not imposed upon it. It was chosen, planned, and lobbied for. Prime Minister Benjamin Netanyahu spent the better part of three decades arguing that the Islamic Republic constituted an existential threat that only force could resolve, and in February 2026, he persuaded the second Trump administration to act on that argument. Operation Epic Fury opened on 28 February with nearly 900 strikes in twelve hours, the killing of Supreme Leader Ali Khamenei, and the systematic targeting of Iran’s senior military and political class. The premise is familiar: overwhelming force, applied without warning and with American backing, could deliver a strategic victory of generational consequence.
The war Israel chose has become the war it cannot finish, cannot abandon, and cannot sustain.
What this war has produced instead is a structural trap. Iran’s regime survives. Its missile program has been damaged but not eliminated. The Strait of Hormuz remains effectively closed. Israeli interceptor stocks are critically depleted, dependency on US resupply has been exposed, and the domestic political coalition is fracturing under the weight of expectations Netanyahu himself created. The war Israel chose has become the war it cannot finish, cannot abandon, and cannot sustain. This analysis examines how each of those three exits have been closed off and why even an indefinite ceasefire now favors Tehran rather than Tel Aviv.
The Architecture of the Trap
Tehran is too distant for occupation, too populous for collapse, too diversified for decapitation, and too patient for Israeli operational tempo.
The dilemma was doctrinal before it was operational. Since 1948, Israeli strategic culture has been organized around the proposition that decisive military victories generate political settlements on Israeli terms. Each previous war with an Arab state reinforced that proposition. Hezbollah and Hamas, and to a lesser extent the Houthis, complicated it, and Iran has now broken it. Tehran is too distant for occupation, too populous for collapse, too diversified for decapitation, and too patient for Israeli operational tempo. The expectation that an opening salvo against the leadership tier would produce a Mossad-engineered popular uprising has been quietly abandoned, with American and Israeli intelligence officials privately conceding that the conditions never existed. As one former Trump-administration negotiator put it, Iranians will not bring the majority of their population into the streets while protest still carries the risk of being shot.
Netanyahu inherited and reinforced a doctrine that cannot accommodate stalemate. Israel’s deterrence rests on the perception that escalation always favors the Israel Defense Force (IDF) and that any opening clash will close on Israeli terms. A war that ends without that closure does not merely fail to add to the deterrent: it actively erodes it. This is why the Israeli political class is now caught between two unacceptable outcomes. Stopping without Iranian capitulation will be read within Israel and across the region as the first major war Israel did not win. Continuing without the means to escalate decisively risks turning that perception into a fact.
The Illusion of Victory
Tactically, the campaign has been impressive. The Center for Strategic and International Studies (CSIC) assesses that Iranian missile attacks fell by approximately ninety per cent within the first week of strikes and that more than 250 senior Iranian figures have been killed, including most of the senior military leadership. The US military claims to have struck more than 13,000 Iranian targets and the Joint Chiefs estimate that around eighty per cent of Iran’s missile facilities are no longer operational. The Iranian navy has been substantially destroyed in the Gulf, and air defenses have been comprehensively suppressed.
Iran does not need to win on the battlefield. It needs only to deny Israel a recognizable victory.
These outcomes are real, but they are not victory. None of the political objectives announced for the war have been achieved. Khamenei’s death produced a dynastic succession rather than a collapse, with his son taking over the office of Supreme Leader. The nuclear program has been set back, but Iran has formally declared International Atomic Energy Agency (IAEA) safeguards inoperative and retained its enriched-uranium stockpile, leaving the door open to a hedging posture rather than disarmament. The Iranian Revolutionary Guard Corp (IRGC) as an institution remains intact. Hezbollah, far from being neutralized, has opened a second front from southern Lebanon, where the IDF is again sustaining casualties from drone warfare it had not anticipated. Tehran’s grip on the Strait of Hormuz, where shipping volume has collapsed to roughly five per cent of pre-war levels, gives it economic leverage over global energy markets that no air campaign can dislodge.
The aforementioned CSIS assessment captures the asymmetry with unusual precision: the United States and Israel are doing well in traditional military terms but many of the highest costs lie outside the theater of conflict and involve the economic costs to US allies and the diplomatic damage to Washington itself. Iran does not need to win on the battlefield. It needs only to deny Israel a recognizable victory. As Robert Pape has argued in Foreign Affairs, this is the logic of horizontal escalation: extending the conflict beyond direct military exchange into political and economic domains where time favors the side absorbing pain rather than the side imposing it.
The Cost of Stopping
The conditional ceasefire announced on April 8th, mediated by Pakistan, was not a resolution. It was a pause that exposed the structural weakness of the Israeli position. Iran’s regime is intact. Its uranium remains. The IRGC, in the words of Israeli opposition leader Yair Lapid, is in a stronger position than before the war. Former IDF chief of staff Gadi Eisenkot has publicly framed the ceasefire as one in a series of agreements imposed on Israel by Washington rather than negotiated by it. Yair Golan, leader of the left-wing Democrats, called the result one of the most severe strategic failures Israel has ever known.
Each successive ceasefire extension confirms the assessment that the conclusion of the war is out of his control. Every additional week of pause allows Iran to disperse, harden, and reconstitute. Every additional week erodes the operational rationale for continuation.
The polling tracks the political damage. Reporting on a recent Institute for National Security Studies (INSS) survey, Chatham House notes that sixty-one per cent of Israelis reject the ceasefire and only thirty per cent now believe the regime in Tehran has been significantly damaged. This is down from the sixty-nine per cent who believed so when the war began. For Netanyahu, halting now means accepting publicly what is already privately understood: Israel has fought a war whose announced end-state – regime change in Tehran – was always beyond its reach and that its junior partnership with the United States is more constraining than the political class has admitted. Each successive ceasefire extension confirms the assessment that the conclusion of the war is out of his control. Every additional week of pause allows Iran to disperse, harden, and reconstitute. Every additional week erodes the operational rationale for continuation. A ceasefire of indefinite duration is not stability; it is the slow conversion of Iran’s tactical losses into strategic recovery.
The Price of Continuing
If stopping is unacceptable, continuing is unsustainable. The most striking evidence is in the air-defense ledger. A March 2026 Royal United Services Institute (RUSI) assessment, drawing on pre-war estimates from the Payne Institute, calculated that by March 24th Israel had expended 122 of its 150 Arrow 2 and Arrow 3 interceptors and roughly half of the Terminal High Altitude Area Defense (THAAD) missiles deployed in theatre. By the eve of the April ceasefire, Trump-administration officials briefed that Israeli interceptor stocks had fallen into double digits with commanders openly rationing engagements and choosing which incoming missiles to defend against. Coalition forces are estimated to have expended approximately 11,294 munitions in the first sixteen days of the conflict, at a combined cost of around $26 billion.
There is no occupation option and no plausible attrition curve in which Israel exhausts Iran before Iran exhausts Israeli stockpiles, reservist patience, or American patience.
The economics are punitive: each Arrow 3 round costs roughly three to four million dollars and takes months to produce; THAAD costs around twelve million dollars per round. Iran can manufacture cluster-warhead missiles faster than Israel can replace its interceptors, and the impact rate of Iranian strikes against Israeli targets reportedly rose from three per cent to twenty-seven per cent in the first weeks of the war. This is the material face of dependency; Israel cannot wage this war without American interceptors, American refueling, American air-defense assets in the Gulf protecting US bases, and American diplomatic cover at the United Nations Security Council. The April announcement of a US-Israeli partnership to accelerate Arrow production confirmed what the war exposed: an independent Israeli deterrent against Iran does not exist.
The pressure is not only material. The IDF chief of staff has acknowledged a structural manpower shortfall of roughly 15 thousand soldiers. Reservist fatigue, ultra-Orthodox conscription disputes, and a deepening political crisis around Netanyahu’s chief of staff are all visible pressure points. Chatham House has assessed that Netanyahu’s “Super-Sparta” doctrine – the institutionalization of permanent low-to-mid-intensity warfare – is colliding with the fundamental limits of Israeli human and material resources. Tel Aviv saw renewed mass protests on May 2nd. The opposition is gaining ground but cannot form a government without Arab parties, leaving Netanyahu in office and unable to deliver – the worst possible combination for Israeli grand strategy. Demographic asymmetries compound material ones. Israel’s population is roughly ten million; Iran’s is more than ninety million. There is no occupation option and no plausible attrition curve in which Israel exhausts Iran before Iran exhausts Israeli stockpiles, reservist patience, or American patience.
The Annihilation Fallacy and the Asymmetry of Time
The only outcome that would resolve the dilemma in Israel’s favor, the complete or near-complete destruction of Iranian state capacity, is not available. Iran is not Iraq in 1991 or Libya in 2011. It is a continental state with strategic depth, hardened underground missile infrastructure, a substantial diaspora, and partners in Beijing and Moscow whose interest, as Alterman and Vaez argue in Foreign Affairs, lies in letting Washington bear the costs of an open-ended campaign while quietly extending their own influence. China imports roughly 750,000 barrels of Iranian crude per day and has a structural interest in Iranian state continuity. Russia benefits from elevated energy prices and from the diversion of U.S. munitions away from Ukraine. Time, in this configuration, is an Iranian weapon. Every interceptor fired and not replaced, every additional reservist call-up, and every week of disruption to shipping in the strait of Hormuz that pushes Gulf states toward hedging postures narrows Israel’s operational horizon. A ceasefire of unlimited duration does not freeze the contest. It hands Iran the one resource it most requires: time to reconstitute, procure, disperse, and wait.
Conclusion
Tehran does not need to defeat Israel; it needs only to outlast it.
Israel’s predicament is not the product of a single tactical error. It is the predictable outcome of its doctrine of regional control applied to an adversary. The war Israel chose has produced a battlefield in which victory is structurally unavailable, withdrawal is politically unaffordable, and continuation is materially unsustainable. The annihilation outcome that would resolve the dilemma is not on the table and the negotiated outcome that would limit the damage requires Israel to accept terms it has spent decades refusing to consider. As the author has previously argued in Small Wars Journal, the war was launched without a coherent end-state and on dangerously optimistic assumptions about Iranian fragility. Tehran does not need to defeat Israel; it needs only to outlast it. On current trajectories, that is the more probable result.
