A Campaign With No Known Full Scope or Duration

Trump ordered the Iran campaign himself and claimed his own constitutional powers as its authority. Congress had not authorized it. Within 25 days, CENTCOM reported more than 10,000 targets struck, and Congress's research service put an estimated 50,000 American servicemembers in and around the region.

House Document 119-139, letter to the Speaker of the House of Representatives

Although the United States desires a quick and enduring peace, it is not possible at this time to know the full scope and duration of military operations that may be necessary.

2.1 · The Cost, and the Victory That Did Not End the War

Children Killed at a School in Minab

Children were killed at Minab's school; published death counts differed. The UN mission's September report relayed a local prosecutor's final count of 156 deaths and independent information asserting 157 deaths, including 123 children. A UN mission later found reasonable grounds to believe U.S. strikes on Minab and Lamerd constituted war crimes. In finding recklessness at Minab, the mission cited statements by Trump and Hegseth dismissing binding obligations under international humanitarian law, alongside outdated targeting data and the school's readily identifiable civilian features; it concluded that U.S. failures went beyond negligence.

He Sought a Quick Peace. The Fighting Returned.

Trump said the United States wanted a quick and enduring peace, and by April 1 he said its military objectives would soon be complete. Iran suffered major military losses, but CRS also reported surviving missile and naval capabilities and renewed missile production. The June agreement collapsed and by October safe commercial passage through the Strait of Hormuz remained unsettled.

Both chambers voted for Iran withdrawal in June, 215-208 in the House and 50-48 in the Senate. Their resolution never became law and exempted forces needed for imminent defense, subject to the War Powers Resolution's 60-day condition. The House also supported war funding in July and passed further withdrawal measures in July and September.

He Rejected His Intelligence Assessment, Then Bombed Three Nuclear Sites

The 2025 intelligence assessment said Iran was not building a nuclear weapon, while warning that pressure had probably grown on its leader to revive the program. Trump said his intelligence community was wrong and ordered strikes on three Iranian nuclear facilities the following night.

He Sent More Than 150 Aircraft to Seize Maduro

Trump ordered the military operation that captured Nicolás Maduro and Cilia Flores for federal prosecution. The government defended it as law enforcement supported by military force. The arrest succeeded, but the precedent allowing a court to try an abducted defendant does not decide whether the President had authority to order the military operation.

Trump's Defense, and the War Decision It Does Not Settle

Trump claimed constitutional authority to defend American forces and allies, and presidents of both parties have ordered force without first obtaining a war authorization. Congress's withdrawal resolution exempted imminent defense and rests on a mechanism CRS calls constitutionally suspect, so the later strikes' dates alone do not prove that they defied Congress. The separate question is whether beginning a campaign of this scale and risk required Congress's prior approval under the executive branch's own test.

5.2 · Presidential Power Is Not a Substitute for Congress's Decision

His War Decision Cost Lives and Billions

Trump signed the reports and said he directed the operations. The charge is his choice to commit Americans to a large war without Congress's authorization, a campaign he continued directing after the June withdrawal vote with its imminent-defense exception.
