The War's Costs Changed Address

On Monday the U.S. Air Force moved at least 24 aircraft out of RAF Mildenhall and raised two British bases to Force Protection Condition Charlie, the alert level that signals a specific, credible threat rather than routine caution. ^[1] On the same day, the same government declared the war in Iran "effectively over." The first of the costs' new addresses is Iran's winter. The country now projects a shortfall of 430 million cubic metres of gas and warns that 11 of its 31 provinces could face cuts. ^[2][3] The first phase of the fighting destroyed roughly a fifth of Iran's daily production capacity at South Pars, where four processing plants were damaged ^[3], in a country where gas-fired plants generate 80 percent of electricity. ^[2] What the war added was a fifth of the capacity, broken on top of a chronic seasonal squeeze: in December 2025, before this war began in February, Iran had already halted gas exports to Iraq during a cold spell to keep heat at home. ^[4] Iran's money told the same story, a season later. Washington's pressure campaign was porous through the spring: Iran was still moving around $31 billion of oil to China on a shadow fleet of aging tankers, most of its foreign sales. ^[5] By October that lifeline was gone, with tankers stranded off Sri Lanka short of food and fuel and ports refusing to service them. Analysts expected the smuggling revenue to drop to zero by December. ^[6] The American side of the ledger is written in budgets and bases. The evacuation from Mildenhall was not the first: in September, 12 B-1 bombers left RAF Fairford after British police arrested five men over an alleged Iran-backed plot involving petrol vans, and MI5 now counts more than 20 potentially lethal Iran-linked plots in the past year. ^[1] Three Iranians went on trial in London in October for an alleged Tehran-directed surveillance plot. ^[7] The new defense budget writes $14 billion of counter-drone protection into the line items. ^[1] Operation Epic Fury has run more than 13,000 strikes toward a projected $37.5 billion, and a quarter of the MQ-9 Reaper fleet is gone; Iran's own strikes damaged or destroyed more than 200 U.S. facilities and killed at least 18 service members. ^[8] The president removed any doubt about why the aircraft moved.

Iran militarily is effectively over. — Donald Trump

The secretary of state does not describe the end of major combat as an end at all.

The economic campaign (against Iran) is so devastating that right now there is no need for major combat operations. — Marco Rubio

He puts the point as an inversion of who is blockaded.

The only country in the world that cannot get a single barrel of oil through the Straits of Hormuz is Iran. — Marco Rubio

The U.S. Navy escorts 13 to 14 million barrels a day of other nations' oil through the same waterway. ^[9] Rubio states the substitution outright.

We don't need to conduct military strikes if we're achieving the same objective through economic means and economic pressure. That's not stalemate. — Marco Rubio

What "over" stopped was the daily rhythm of major strikes. Trump resists Netanyahu's daily pressure for them and describes what continues instead.

We do minor strikes, but they knock out. — Donald Trump

What kept running was everything quieter. The day before the "over" declarations, Iran converted its military doctrine from defensive to offensive and dropped its self-imposed limit on ballistic missile range. ^[10] The State Department is still offering up to $20 million for information on Iran's nuclear facilities and personnel. ^[11] The diplomatic track is deadlocked: Iran wants its assets unfrozen and the naval blockade lifted before it will negotiate, terms Rubio calls unrealistic. ^[12] Rezaei's answer is no less rigid.

Iran won’t remove even a single particle of enriched nuclear material from the country. — Mohsen Rezaei

December is where the two clocks meet: the month the smuggling revenue is expected to reach zero ^[6] is the month winter gas demand peaks, and Iran's planning chief has warned that pipeline pressure could force gas cuts across entire cities. ^[2]
