For thirteen successive nights, American aircraft and missiles struck Iran. Then, without a ceasefire, a settlement or any visible Iranian concession, the bombing stopped. The silence over southern Iran was not caused by weather, mechanical failure or a shortage of targets. It followed a decision by Donald Trump after his most senior commanders warned that the campaign had reached the limits of its effectiveness and that a wider attack could leave American forces dangerously exposed to Iranian retaliation.

Only days earlier, the United States had been preparing for something much larger. Additional combat aircraft had been moved towards the region. Bombers were placed on alert. Tankers, special forces and medical personnel were repositioned. More than 150 additional medics were sent to Landstuhl Regional Medical Center in Germany, the principal hospital receiving American casualties evacuated from the Middle East.

The preparations suggested that Trump’s threatened “massive attack” was more than rhetoric. The Pentagon had been instructed to provide options for expanding the war beyond the coastal installations, missile positions and naval facilities struck during the previous two weeks.

Yet the larger attack did not happen.

Instead, Trump stopped the operation on Friday, 24 July. Iran reciprocated, announcing that it would suspend retaliatory attacks for as long as the American pause continued. Washington and Tehran are now exchanging messages through Oman, Pakistan and Qatar while publicly offering sharply different accounts of why the guns fell silent.

Washington says Trump is giving diplomacy room. Tehran says America stopped because its bombing failed. Both explanations contain part of the truth.

The meeting that prepared a larger war

On 14 July, Trump convened senior national security officials in the White House Situation Room. The purpose was to consider an offensive considerably wider than the nightly attacks around the Strait of Hormuz.

The existing campaign had concentrated on Iranian coastal surveillance, missile sites, naval bases, drone storage facilities, communications systems and installations associated with attacks on commercial shipping. These strikes inflicted substantial damage, but they did not achieve Washington’s immediate political objective.

Iran still retained practical control over passage through the Strait.

Commercial traffic remained severely restricted. Iranian forces continued to intercept vessels, prescribe authorised routes and assert that ships required Tehran’s permission to pass safely. The United States possessed overwhelming air and naval power, but it had not converted that power into reliable control of the waterway.

The larger operation considered in Washington would have widened the target list. Remaining missile manufacturing sites, command centres, nuclear facilities and important military infrastructure were examined. Reports also suggested that American planners were considering deeply buried installations, including the complex commonly called Pickaxe Mountain.

The movement of forces followed. F 16 and F 35 aircraft were repositioned. B 1 bombers entered the renewed campaign. Refuelling aircraft increased their operations. Special forces were moved to provide Trump with additional options.

The reinforcement of Landstuhl was another part of the same preparation. The medics were sent to Germany, not from Germany into the Gulf. Their function was to expand the hospital’s capacity to receive casualties evacuated from American bases across the Middle East.

That distinction matters, but it does not make the deployment insignificant. Military planners do not reinforce the principal overseas trauma centre by more than 150 personnel unless they anticipate a credible possibility of substantial casualties.

The United States was preparing both to deliver a larger attack and to absorb Iran’s response.

The generals’ warning

The decisive meeting came ten days later.

Admiral Brad Cooper, the commander of United States Central Command, advised that the bombing around Hormuz had reached the limit of what it could usefully accomplish. Further strikes could destroy additional Iranian equipment, but there was no convincing assurance that they would force Tehran to surrender control of the Strait.

This was not an argument that America lacked military power. It was an argument about the relationship between military action and political result.

Bombing can destroy a radar, a missile launcher or a naval headquarters. It cannot necessarily compel a large country to abandon a strategic position it regards as essential to its survival. Iran could disperse launchers, use smaller boats, deploy mines, fire from concealed positions and continue threatening American bases and Gulf infrastructure.

General Dan Caine, chairman of the Joint Chiefs of Staff, delivered a second warning. The problem was not principally the number of offensive bombs available to the United States. It was the continuing consumption of defensive interceptors required to protect American troops, ships and allied cities from Iranian missiles and drones.

Every American attack created the possibility of an Iranian response. That response had to be detected and, where possible, intercepted by Patriot, THAAD and naval air defence systems. Stocks of those interceptors were under growing pressure.

America could continue bombing Iran while gradually weakening the shield protecting its own forces.

Vice President JD Vance supplied the political argument. A wider campaign risked pulling the United States into another indefinite Middle Eastern war with no agreed ending. American casualties were rising, oil had moved above $100, and the conflict was becoming increasingly difficult to reconcile with Trump’s promise to avoid costly foreign wars.

Trump was therefore confronted with an unwelcome calculation. The United States could inflict greater destruction on Iran, but the generals could not promise that the destruction would open the Strait, end Iranian retaliation or conclude the war.

He ordered the military to hold off.

What Washington says

The public American explanation is that Trump chose diplomacy from a position of strength.

Mike Waltz, the American ambassador to the United Nations, said the president was giving negotiations “a little bit of room”. Administration officials insist that the armed forces remain fully capable of renewing attacks and deny that shortages dictated the decision.

Washington’s position is that Iran must permit free and secure commercial passage through Hormuz, cease attacks on shipping and enter meaningful negotiations. If Tehran refuses, American military action can resume.

This is the language Trump requires politically. He cannot admit that Iran’s retaliation, rising casualties or depleted defensive stocks compelled him to stop. The pause must be presented as a voluntary act by a dominant power offering its opponent a final opportunity to make an agreement.

The private leaks tell a more complicated story.

Senior officers reportedly concluded that the bombing was producing diminishing returns. The danger to American forces was increasing, while the political objective remained beyond reach. The Pentagon had prepared the larger attack, but its leaders warned the president about the probable consequences.

Those leaks also protect the military institution. If Trump resumes the campaign and American casualties increase, the commanders can demonstrate that they warned him. If political hawks accuse them of weakness, they can answer that they supplied every requested military option and left the final decision to the president.

What Iran says

Tehran has constructed the opposite narrative.

Iranian officials say they did not request negotiations and have made no concession over the Strait. They describe the suspension of their attacks as reciprocal: Iran will refrain from striking American forces and regional allies only while Washington refrains from bombing Iran.

If America attacks again, Iran says it will respond.

Tehran continues to insist that it controls navigation through the Strait and retains the right to regulate vessels passing close to its territory. Iranian forces have continued intercepting or turning back ships they accuse of using unauthorised routes.

Iran’s denial that negotiations are taking place should not be read literally. Messages are plainly passing through Omani, Pakistani and Qatari intermediaries. Tehran distinguishes between formal negotiations with the United States and indirect exchanges conducted through regional governments.

That distinction allows Iran to pursue an accommodation without admitting that American bombing forced it to seek peace.

Neither side wants to acknowledge the compromise already operating in practice. America has stopped bombing without obtaining Iran’s surrender. Iran has stopped retaliating without obtaining the removal of the American blockade.

The result is not peace. It is an undeclared and conditional suspension of attacks.

Netanyahu comes to Washington

It is at this precarious moment that Benjamin Netanyahu arrives in Washington.

Iran will be the principal subject of his meeting with Trump. The Israeli prime minister’s purpose will not merely be to receive a briefing. He will attempt to change the calculation that produced Friday’s decision.

Netanyahu’s argument is likely to be that America has stopped at precisely the wrong moment. Iran has suffered months of attacks. Its military, naval and missile infrastructure has been damaged. Its defensive systems have been placed under pressure. Allowing Tehran time to recover, rebuild and declare victory would sacrifice the advantage created by the campaign.

Israel’s objective is also wider than America’s immediate struggle over Hormuz.

Washington wants commercial shipping restored and attacks on American forces stopped. Israel seeks the lasting destruction of Iran’s nuclear capacity, missile production and ability to support Hezbollah and other regional forces. An arrangement that opens shipping while leaving those capabilities intact may satisfy Trump without satisfying Netanyahu.

The Israeli prime minister is therefore expected to seek assurances that any agreement will preserve Israel’s freedom to attack Iran, Hezbollah and remaining nuclear facilities. He will resist any bargain in which Iran restrains shipping attacks in return for protection from Israeli action.

Netanyahu may arrive with intelligence concerning buried nuclear installations, missile production or planned Iranian operations. Such material could be used to argue that postponing action creates a greater danger than continuing it.

But Israel’s case has a serious weakness. It would be American bases, ships and personnel that absorbed much of Iran’s retaliation. Israel can advocate a longer campaign, but it cannot guarantee that bombing will make Tehran surrender, reopen Hormuz or abandon its nuclear knowledge.

Nor can it guarantee that Iran will confine its response to military targets. Power stations, ports, refineries, desalination facilities and commercial routes across the Gulf could all become instruments of coercion.

Trump may therefore ask Netanyahu what the American generals have already asked: what political result will the next set of targets produce?

America and Israel no longer want exactly the same war

The meeting may reveal a widening difference between Washington and Jerusalem.

Netanyahu believes that Iranian power must be reduced until it can no longer threaten Israel. Trump increasingly appears to want a visible concession that allows him to declare victory and lower the immediate cost to America.

That does not make Trump an opponent of Israel or an advocate of reconciliation with Iran. It means his preferred endpoint may now be narrower than Netanyahu’s.

A wider transaction is possible. Netanyahu may offer cooperation with American plans in Gaza or restraint in Lebanon in exchange for continued pressure on Iran, additional weapons and guarantees concerning future Israeli operations.

Trump may, in return, demand that Israel avoid actions that would destroy an arrangement over Hormuz. The decision by Israel’s security cabinet to permit a limited international stabilisation force into parts of Gaza, announced immediately before the visit, may be intended to improve the atmosphere for such a bargain.

Nothing, however, has been settled.

American bombing has stopped. Iranian retaliation has largely stopped. But Iran has not surrendered control over navigation, America has not removed its blockade, and no formal ceasefire has been announced. The forces assembled for escalation remain in place.

Trump halted an attack that the Pentagon had prepared. His commanders gave him a military reason to pause. Iranian resistance gave him a political reason to seek an exit. Netanyahu has come to Washington to give him a reason to reverse course.

The bombing stopped because American power was no longer producing a clear political result. Israel’s prime minister must now persuade Trump that the greater danger lies not in continuing the war, but in allowing Iran to believe it has survived it.
