What happened this weekend in Iran
Between February 28 and March 1, 2026, President Donald Trump used his War Powers to direct a major U.S. military campaign in Iran alongside Israel, described publicly as “major combat operations” and widely reported as Operation “Epic Fury.” U.S. reporting describes large-scale strikes against Iranian military infrastructure and command-and-control targets, with Iran launching retaliatory attacks in the region.
Trump framed the operation as defensive—aimed at eliminating “imminent threats” and preventing Iran from advancing nuclear and missile capabilities. At the same time, members of Congress from both parties quickly raised war-powers concerns, emphasizing that the strikes began without an Iran-specific authorization from Congress and calling for votes to restrain or end hostilities absent congressional approval.
The road to this point: a short recent history
The current confrontation did not start overnight. Reporting describes a backdrop of escalating pressure and failed diplomacy, including indirect nuclear talks (including meetings reported in Muscat and later discussions in Geneva) that ended without a deal, plus a major U.S. military buildup in the region in the weeks leading up to the strikes. News coverage also ties the crisis to internal unrest in Iran and the regime’s violent repression—facts that influenced rhetoric in Washington even if they do not, by themselves, create domestic legal authority to wage war.
By the time U.S. aircraft began striking targets, the legal and political debate had already ignited: did the president act within his constitutional powers, or did he cross the line into a conflict that only Congress can authorize?
The core question: what legal authority does Trump have to use force in Iran?
U.S. domestic law generally recognizes two main buckets of authority for overseas military force:
- The Constitution (Article II) — The president serves as Commander in Chief and can direct U.S. forces, especially to repel attacks, protect U.S. personnel, and respond to urgent threats. Presidents of both parties have relied on Article II to justify limited or time-sensitive uses of force when they claim the action protects Americans and national interests.
- Congressional authorization — The Constitution gives Congress the power to declare war and fund, regulate, and authorize military operations. When hostilities broaden or continue, presidents typically point to a statute: an Authorization for Use of Military Force (AUMF) or a declaration of war.
In this episode, many analysts argue that no existing AUMF cleanly authorizes a major campaign against Iran and that Article II becomes shakier as operations expand in scope, duration, and risk. That criticism strengthens if intelligence briefings undermine the claim that Iran posed an “imminent” attack threat at the moment the U.S. struck.
Where the War Powers Resolution fits
The War Powers Resolution of 1973 tries to force accountability when presidents introduce U.S. forces into hostilities. In broad terms, it pushes the executive branch to notify Congress and limits continued engagement unless Congress authorizes the action (or another narrow exception applies).
That’s why you already see lawmakers moving toward war powers resolutions aimed at restricting or ending the operation unless Congress votes yes. Whether Congress can sustain that pressure politically remains the practical check, because courts rarely decide war-powers disputes in real time.
Purim, Persia, and the power of “imminent threat” stories
It is perhaps fitting that this latest military action unfolds just as the Jewish calendar turns to Purim—a holiday rooted in another drama of salvation set in Persia, the same land we now call Iran. The Book of Esther recounts how a threatened people faced annihilation amid plots, decrees, and competing versions of truth. Then, as now, leaders framed extraordinary measures as matters of survival, invoking the language of immediacy and existential danger to justify decisive acts. In both stories, urgency became the moral and political currency that transformed deliberation into action. The echoes are not merely literary. Modern debates over “imminent threats” and necessity—phrases that once belonged to theologians and now belong to lawyers—still carry the power to authorize force and shape public consent. Whether in ancient Shushan or the corridors of Washington, the same tension persists: how much evidence is enough, and how much fear is too much? The Purim story reminds us that courage and discernment can turn the tides of history—and that even in moments of peril, wise leadership can transform fear into deliverance.
Modern precedents: how Presidents used War Powers without new authorization
Modern presidents often test the outer boundary of War Power when they use airpower or “limited” missions without a new AUMF, and Congress often responds with disagreement rather than a clean yes-or-no authorization. In 1999, President Clinton joined NATO’s Kosovo air campaign without a new statute tailored to that conflict, and the House’s reaction captured the institutional stalemate: it tied 213–213 on a resolution that would have expressly authorized the air operations, so the measure failed and Congress never supplied clear affirmative authority. That deadlock became the story—Clinton continued the campaign while Congress signaled deep division and effectively allowed the operation to proceed without a definitive vote to authorize or to stop it.

President Obama faced a similar War Power fight in Libya (2011). He initiated U.S. military action in support of NATO operations without seeking a new AUMF, then his administration argued that the U.S. role did not trigger the War Powers Resolution’s 60-day termination provision because the United States allegedly did not engage in “hostilities” as the statute contemplated. Critics in Congress attacked that reasoning and warned that it invited future presidents to re-label sustained combat as something less than “hostilities” to avoid a hard authorization vote. The Libya episode matters because it shows a recurring executive strategy: presidents describe operations as limited, remote, or coalition-led to defend unilateral action, while Congress struggles to convert objections into binding constraints.
President Biden continued the modern pattern in two widely cited episodes. First, in February 2021, he ordered airstrikes in Syria and relied on Article II constitutional authority as domestic legal justification, framing the action as a defensive response connected to attacks on U.S. interests. Second, during U.S. military actions against the Houthis (linked to Red Sea shipping attacks), his administration repeatedly notified Congress “consistent with” the War Powers Resolution through presidential letters and reports, which prompted bipartisan criticism from lawmakers who argued he should seek explicit authorization before expanding hostilities. Together, these examples show the real-world War Power dynamic in modern times: presidents act quickly under Article II and reporting practices, and Congress responds with oversight demands and occasional War Powers pushes—but often without mustering a durable legislative endpoint.
Bottom line for 2026
President Trump’s strongest domestic argument is Article II: he says he acted to protect Americans and eliminate imminent threats. Unless Congress disagrees and acts to restrict funding, the action is legal and in line with past precedent.
If the operation continues, the legal center of gravity shifts to Congress. Expect the next chapter to play out through War Powers votes, public disclosures, and the administration’s effort to frame the campaign as necessary, time-limited, and defensive—rather than a new war requiring explicit authorization.
