  "textContent": "**What you need to know**\n\n🔹 Marco Rubio says Operation Epic Fury is over.\n🔹 Congress questioned the war’s legality.\n🔹 War Powers rules shaped the dispute.\n🔹 Republican pressure appears to have constrained Donald Trump.\n\n\n\n\nO  peration Epic Fury is over. Or at least, that’s what the US secretary of state, Marco Rubio, announced on May 5, describing any further US action in the Gulf as purely _“defensive”_.\n\nRubio’s insistence that the conflict the US and Israel launched on February 28 achieved its objectives is open for debate. But this change of tone and terminology is likely to reflect arguments that raged in the US Congress as the war approached the two-month mark at the end of April, about whether the Trump administration must seek congressional approval for the conflict as required by US law.\n\nThe conflict has become the latest episode in a long struggle between the US Congress and the presidency over which branch of government can legitimately start wars. And, in a surprising way, Donald Trump’s actions seem to be pushing power back towards Congress.\n\nThe US constitution splits war powers between the presidency and Congress. It gives Congress the power to raise armies and declare war but makes the president the commander-in-chief of the military. That means that, in theory, you need to get Congress to agree to fund and start a war and the president to agree to wage it.\n\nSince the second world war, this system has been changing. The last time the US formally declared war was in 1942 against Bulgaria, Hungary and Romania – having already declared war on Japan and Germany in December 1941. Since then, presidents have often plunged the country into hostilities on their own authority without getting a declaration of war from Congress.\n\nCongress still needs to fund the military – but, with very few exceptions, the legislature has always done so. Individual members of Congress have generally been happy to let presidents take on the blame for starting wars. After conflicts have started, legislators have been unwilling to cut off funds for the troops in the field. As a result, Congress has given up much of its influence over decisions of war and peace.\n\nBut not entirely. The high point of Congressional pushback was in 1973, during the tail end of the Vietnam war, which by then had become extremely unpopular. In this context, Congress challenged the executive branch by passing the 1973 War Powers Resolution (also known as the War Powers Act). It’s this law that is shaping the debate over Iran today.\n\nThe War Powers Resolution basically repeats what the constitution says: that Congress has to start wars, but it allows for some flexibility. If there is a surprise attack on US forces, the president can act to repel that attack for 60 days before getting a declaration of war from Congress.\n\nAs reasonable as this may sound, every administration since the War Powers Resolution was passed has questioned its constitutionality and refused to be bound by it.\n\nTo be sure, some presidents have asked Congress for a statement of political support before launching a major war, as they also had done before the War Powers Resolution was passed. For instance, George H.W. Bush did so before the Gulf war of 1990-91. But when doing so, presidents have generally maintained that they did so purely to ensure national unity, and not because the War Powers Resolution required it of them.\n\nPresidents have also launched many interventions in which they ignored the resolution entirely – as Bush himself did in Panama in 1989.\n\nSecretary Marco Rubio hosting a press briefing, 5-May-2026. | FLICKR/US DEPARTMENT OF STATE\n\n##### Unpopular war\n\nAs a result, the resolution has never acted as a meaningful constraint on presidential war-making power. But things may be changing. The war in Iran is so unpopular that Congress asserting its authority over war powers more strongly than any time since the War Powers Resolution was passed. In the process, it is turning the resolution into something that might meaningfully affect the course of the war.\n\nOne reason for this is that even Trump’s Republican supporters in Congress are aware of how unpopular this war is. Many are worried about losing their seats in the midterms later this year. As a result, Congress is stirring. Even senior Republican figures are treating the War Powers Resolution and its 60-day clock as an important constraint on the administration and demanding that the war stop or be authorised by Congress after it passes that mark.\n\nIn response to this political pressure, the Trump administration seems to be paying more attention to the requirements of the War Powers Resolution than most administrations before it.\n\nThe White House is too afraid of Republican opposition to ignore the resolution entirely, particularly when it knows that it may soon have to ask Congress for more funding for the war. Even the argument it made that the 60-day clock has paused during the ceasefire is an indication that it sees the clock as a legitimate thing in the first place.\n\nIf the war starts up again, Republicans will clamour for the administration to come to Congress for a declaration. This would probably trigger a major debate over the conditions that Congress wants to attach regarding strategy, goals and funding.\n\nWhat this shows is that many of the checks and balances of the constitution only work when there is the political will to make them work.\n\n### **GOING FURTHER**\n\n  * ######  Trump tells Congress hostilities with Iran have terminated | CBS News\n\n  * ######  Inside the war powers debate on Iran raging on Capitol Hill | ABC News\n\n  * ######  Congress faces big test on Iran war as 60-day deadline looms | Time\n\n  * ######  Has the US-Iran ceasefire reset the clock on War Powers Act deadline? | Al Jazeera\n\n  * ######  Operation Epic Fury puts Congress and the Constitution to the test | Lawfare\n\n  * ######  Operation Epic Fury and the international law on the use of force | Carnegie Endowment\n\n  * ######  The War Powers Resolution of 1973 | Nixon Library\n\n\n\n\n\n\n\n###\n\n\n\n\n* * *\n\n#### **Sources:**\n\n###### ▪ This piece was originally published in The Conversation and re-published in Europeans TODAY on 7 May 2026. | The author writes in a personal capacity.\n\n###### ▪ **Cover:** Flickr/The White House.
