The Six-Month Cycle Driving the Iran War

Early in the US-Israeli air campaign that began on February 28, Secretary of Defense Pete Hegseth declared that Iranian missile capability had been eliminated outright.

digging out your remaining launchers and missiles, with no ability to replace them. You have no defense industry. — Pete Hegseth

Within seven weeks of the April ceasefire that followed, satellite imagery showed Iranian crews with bulldozers and dump trucks clearing debris from 50 of 69 underground missile tunnel entrances across 18 facilities ^[1]. US intelligence was acknowledging, privately, that Iran was "reconstituting drone production and missile launchers faster than anticipated" ^[1]. By mid-April, Iran's deputy chief of staff had announced a tenfold increase in attack-drone production and framed the rebuilding itself as a strategic victory.

The fact that we have brought the enemy to the negotiating table to talk about our requests and demands is by itself a great victory. — Alireza Sheikhattar

The contradiction between the categorical claim and the physical evidence is not an intelligence failure. It is the engine. The US-Iran war has completed one full cycle in under six months and is already deep into its second. The arc is specific enough to describe beat by beat. On February 28, US and Israeli strikes killed Supreme Leader Ali Khamenei and began a 107-day war ^[2]. By March 6, coalition forces had flown over 3,500 airstrikes, destroying approximately 80 percent of Iran's air defense systems and over 60 percent of its ballistic missile launchers ^[3] — though the 80 percent figure may overstate actual destruction, since Iran employed thermal paint and ground-based decoys to mislead coalition surveillance, meaning some targets assessed as destroyed were decoys ^[3]. On March 16, Iran's Khatam al-Anbiya Central Headquarters announced a fundamental strategic shift: no longer tit-for-tat retaliation, but continuous, successive offensive strikes "designed to make the war prohibitive for the US" ^[4]. A ceasefire took hold in April ^[5]. Both sides continued exchanging strikes through late May even under its nominal terms ^[6]. On June 12, the US and Iran signed the Islamabad Memorandum of Understanding to end the war ^[2]. Donald Trump declared the deal a success and said the conflict could soon be "in the rearview mirror" ^[2]. By June 28, Iran had launched Operation True Promise 4 — a coordinated ballistic-missile and drone campaign against eight US military installations across six countries, destroying a $1.1 billion early-warning radar at Al-Udeid and the US Fifth Fleet headquarters in Bahrain ^[7]. The ceasefire unofficially collapsed by July 12 ^[8]. War resumed on July 16, and as of today — July 24 — US Central Command has conducted 13 consecutive nights of strikes against Iranian naval assets, drone sites, command centers, and coastal surveillance ^[9]. Trump is now weighing a "massive attack" that would be "bigger than ever before" ^[10]. The cycle has lapped itself. Each beat is a specific, dated event. None is disputed. And none of them, lined up, points toward resolution — because the structure beneath them is a set of fixed positions that make every ceasefire a pause, not a settlement. The structural hinge is the Strait of Hormuz. Iran's Foreign Minister Abbas Araghchi has made Tehran's demand categorical: Iran must govern the strait ^[11].

Any attempt to establish new or separate arrangements from those currently being carried out by the Islamic Republic of Iran, will only lead to further complications, delay the reopening of the Strait of Hormuz, and increase the level of tension. — Abbas Araghchi

Secretary of State Marco Rubio's position is equally categorical in the opposite direction ^[12].

They cannot normalise, nor can we tolerate them trying to normalise, a system in which the Iranians decide who gets to use an international waterway and how much you have to pay them to use it. — Marco Rubio

These are not negotiating postures. They are two fixed points that leave no space for a durable agreement. Each ceasefire buys time; none can survive contact with the question of who controls the waterway through which a fifth of the world's oil passes. Mediators from Qatar, Iraq, and Türkiye are already proposing a second ceasefire after the June 17 agreement collapsed ^[13]. Mojtaba Khamenei has already declared Trump's signature on any agreement "worthless" ^[13]. The pattern does not need to be inferred — it is visible in the timeline. What makes this cycle something more than a stalemate is the direction it bends. Iran is not fighting to win on the battlefield. It is fighting to exhaust. Its explicit strategy, documented by the US-Israeli campaign assessment, is "a war of attrition and mosaic warfare" betting on "the economic exhaustion of its adversaries" ^[14]. The March 16 shift to continuous offensive strikes was designed not to defeat the US militarily but to make the war too costly to sustain ^[4]. Iran's deputy chief of staff framed the mere fact of bringing the US to negotiations as "a great victory" — reconstitution itself as the measure of success ^[15]. And the endurance is not purely domestic: Iran's foreign minister has confirmed that Russia provides battlefield data and electronic-warfare assistance, while China protects energy flows through the Strait of Hormuz ^[16]. The attrition runs in both directions, but it does not run equally. The US campaign has cost over $150 billion and killed four American troops in a single week of the renewed fighting ^[10]. Analysts indicate the US faces a "weakened strategic position due to exhausted missile stockpiles" ^[1]. Iran retains approximately 1,000 missiles protected by deep rock layers and 70 percent of its mobile launcher inventory ^[1]. It has demonstrated the capacity to rebuild launch infrastructure faster than the Pentagon anticipated. It has increased drone production tenfold after a previous round of US strikes ^[15]. And it is not the side reporting depleted precision-munition stockpiles. The cycle does not require Iran to match American firepower. It only requires Iran to outlast the supply of US precision munitions and political patience — and to rebuild faster than the next round of strikes can degrade. The side that can do that does not need the other side to lose. It only needs the other side to run out of means.
