Legal and defense experts say the U.S. bombing campaign against Iran constitutes a war launched without congressional authorization, raising serious concerns about presidential overreach
The United States ongoing bombing campaign against Iran amounts to a war launched without congressional authorization, according to a broad range of legal and defense experts. What concerns many of those experts just as much as the conflict itself is what comes next: courts are unlikely to intervene, Congress has already shown it may not act, and some administration officials have signaled open contempt for the international legal frameworks that have governed armed conflict for decades.
The joint U.S. and Israeli attack on Iran began Feb. 28, resulting in the swift killing of Iranian Supreme Leader Ayatollah Ali Khamenei. Six U.S. service members have since died in the conflict, with officials warning early on that additional casualties should be expected. President Donald Trump, in remarks announcing the strikes, acknowledged that American lives could be lost and encouraged the Iranian people to seize control of their own government once the campaign concluded.
The Constitution is clear, but presidents have long tested its limits
The U.S. Constitution explicitly grants Congress, not the president, the power to declare war. Most legal scholars interpret that to mean a president cannot unilaterally initiate a war without legislative approval. Yet Trump did not seek congressional authorization before striking the Iranian government, and administration officials have offered varying justifications for why they believe none was required.
A White House official told USA TODAY that the president has constitutional authority as commander in chief to defend U.S. interests at home and abroad, citing Iran’s ballistic missile program as a direct threat to the U.S. and its allies. The official also pointed to Iran’s decades of support for proxy groups in the Middle East, including Hamas, Hezbollah and the Houthis, as part of the justification for military action.
The War Powers Resolution of 1973, sometimes called the War Powers Act, attempts to define the boundaries of presidential military authority. It states that presidents may only initiate military hostilities without congressional approval in response to a national emergency created by an attack on the U.S., its property or its personnel. It also requires the president to consult Congress before deploying forces and to submit a report to Congress within 48 hours when troops enter hostilities without a formal declaration of war.
Some Democratic lawmakers have argued the administration failed to meet even those baseline requirements. The Senate voted on March 4 against a resolution that would have reined in the military assault, leaving Congress as an unlikely source of restraint.
We are finishing it
The administration’s own language has complicated its legal positioning. Multiple Trump officials, including the president himself, have referred to the campaign as a war, even as others have pushed back against that characterization. Secretary of Defense Pete Hegseth stated on March 2 that the U.S. did not start the war but was finishing it under Trump’s leadership. Meanwhile, Republican lawmakers offered a different framing, with some insisting the strikes represent targeted action rather than a formal war.
Secretary of State Marco Rubio added another dimension to the debate by suggesting that no presidential administration, from either party, has ever accepted the War Powers Act as constitutionally binding. He simultaneously maintained that the administration had complied with the law fully, saying he notified a select group of congressional members before the initial strike and reported to Congress more broadly afterward.
International law and what the administration has said about it
Beyond domestic legal questions, the strikes have raised concerns under international law. The United Nations Charter, ratified by the U.S. Senate in 1945 with an 89-2 vote, generally requires Security Council authorization before a country uses military force, with an exception for self-defense in response to an armed attack or imminent threat of one.
Administration officials have leaned on the imminent threat argument, with both Rubio and House Speaker Mike Johnson suggesting that Israel was going to strike Iran regardless of U.S. involvement, and that Iranian retaliation against American forces would have followed. Trump himself, however, appeared to undercut that framing when he said he may have forced Israel’s hand rather than the other way around, and offered no evidence that Iran was on the verge of striking the U.S. homeland directly. Several national security experts have noted that Iran was likely years away from developing ballistic missiles capable of reaching U.S. soil.
Hegseth was more direct in dismissing the relevance of international legal frameworks altogether, stating during a March 2 press conference that the U.S. was conducting its campaign regardless of what international institutions say and would operate under no restrictive rules of engagement.
That posture has alarmed legal observers well beyond the question of this particular conflict. Former White House ethics lawyer Richard Painter, who served under President George W. Bush told USA TODAY that the U.S. is moving rapidly toward a vision of war powers in which military strength alone determines what is permissible, a framework that could embolden other nations to apply the same logic to their own military ambitions.
