U.S. House passes Iran war measure for third time

The House vote

The vote was 220-204, with seven Republicans joining Democrats on the House measure. It was the third time the chamber had approved a resolution calling for an end to the war. The measure passed 49 days before the November 2026 midterm elections.

Mariannette Miller-Meeks and Zach Nunn of Iowa, along with Nancy Mace of South Carolina, were the three Republicans who newly supported the resolution. Thomas Massie, Tom Barrett, Warren Davidson and Brian Fitzpatrick had backed earlier measures.

The Senate’s response is uncertain. A similar House resolution passed in July 2026 but had not been considered by the Senate, and Democrats planned to try again later in the week.

The war’s cost

The Congressional Budget Office estimated that the U.S.-Israeli war cost the Pentagon $38.1 billion from its outbreak in February through Aug. 1. The budget office said another month of fighting could cost $2 billion to $3 billion.

The agency also projects that the war could add half a percentage point to annual inflation by the first quarter of next year. It said the conflict had used as much as two-thirds of the U.S. missile-defense interceptors since June 2025. Replacing them would take at least five years.

The Congressional Budget Office’s estimate gives lawmakers a measure of the financial and military resources tied to the House vote. The Pentagon’s separate inspector general report described damage of about $184 million to hundreds of buildings and other structures at U.S. military bases across the Middle East after Iranian strikes.

Iran’s warnings

Iranian officials have threatened broader retaliation if the United States launches another attack. Hossein Mohebbi, a spokesman for Iran’s Islamic Revolutionary Guard Corps, said Iran would use “new weapons with new capabilities” and change the geography of the war, according to NBC News.

Iran’s Chatam al-Anbija military headquarters also warned that U.S. bases and interests in the region would face continuous attacks. It said countries that support a U.S. attack would be treated as accomplices, Bluewin reported. Mohsen Resai, secretary-general of Iran’s National Security Council, separately threatened attacks on U.S. ships anywhere in the Indian Ocean if new attacks took place.

Pressure beyond Washington

The conflict has affected energy and shipping routes beyond the battlefield. Iran has blocked the Strait of Hormuz, while its Yemeni allies have attacked ships and threatened another key waterway, NBC News reported. Seventeen commodity vessels crossed Hormuz over one weekend, down from 37 the previous weekend.

That reduced traffic matters to shippers and fuel buyers because the fighting has pushed up oil and diesel prices and added to inflation pressures in the United States and the global economy. The House measure now moves into a period of uncertainty before the November 2026 elections.
