Key takeaway

Operation Sledgehammer is the Pentagon's procedural escape hatch from the War Powers Resolution exposure left by Operation EPIC FURY.

The Pentagon is considering renaming any resumed Iran campaign Operation Sledgehammer, two US officials told NBC News on Tuesday 12 May. The stated rationale is procedural: a new named operation creates an untested argument that the War Powers Resolution's 60-day congressional-authorisation clock restarts from zero, displacing the exposure left by Operation EPIC FURY, the original US Iran operation whose clock ran from 28 February and lapsed on 29 April without authorisation. The War Powers Resolution is the 1973 statute that requires a presidential withdrawal from hostilities within 60 days unless Congress votes authorisation.

The rename sits on top of Defence Secretary Pete Hegseth's sworn Senate Armed Services Committee testimony on 12 May that Article 2 of the US Constitution covers the strikes and no Authorisation for the Use of Military Force is required. Hegseth's Article 2 claim is the primary cover; Sledgehammer is the fallback if a federal court or a House majority forces accountability. Senator Lisa Murkowski's Iran AUMF has stayed unfiled since Hegseth destroyed its rationale, removing the only Republican-led legislative vehicle that would have constrained The Administration.

The White House presidential-actions index recorded zero signed Iran instruments on 12-13 May, the deliberate documentary silence that lets executive lawyers argue any future operation is a new matter. The House came within one vote of breaking that silence: the seventh war-powers resolution tied 212-212 on 14 May. Sledgehammer's purpose is to make that vote moot before it happens again. Declare EPIC FURY ended, name the next campaign, argue the clock starts again.

Deep Analysis

In plain English

The US Congress passed a law in 1973 called the War Powers Resolution. It says the President can send troops into combat, but if Congress does not formally approve the war within 60 days, the President must stop. The Iran war started on 28 February 2026. The 60-day deadline passed on 29 April without Congress voting. The Pentagon is now considering giving any resumed military operation a new name, 'Operation Sledgehammer', arguing that a new name means the 60-day clock starts again from zero. Most legal experts say that does not work because the law attaches to the fighting, not the name on the operation, but the argument has never been tested in court.

Deep Analysis

Root Causes

The Administration's fundamental constraint is The White House's own doctrine, stated publicly by Hegseth under oath on 12 May: Article 2 of the Constitution provides sufficient authority, and an AUMF is not required.

That testimony closes the path to retroactive congressional authorisation, because requesting an AUMF would implicitly concede the Article 2 claim is insufficient. The rename strategy exists precisely because The Administration cannot seek the authorisation it publicly declared unnecessary.

Murkowski's Iran AUMF was the only legislative vehicle that could have resolved the clock problem with Republican cover. After Hegseth's testimony, filing the AUMF would require Republicans to contradict a sitting Defence Secretary's sworn testimony on their own party's war. The Sledgehammer rename is The Administration's workaround for a political trap it built for itself.

Escalation

The rename strategy signals The Administration intends to continue or resume kinetic operations beyond the current legal exposure window, without seeking congressional authorisation. This forecloses the most institutionally durable route to de-escalation, a floor vote that would require The Administration to define its objectives publicly.

What could happen next?

Precedent
If the Sledgehammer rename is accepted without legal challenge, it establishes that any President can extend undeclared wars indefinitely by cycling through new operation names, nullifying the War Powers Resolution in practice.
Long term · Medium
Risk
The House 212-212 tie on 14 May (ID:3311) shows a single member shift could force a war powers vote; the rename strategy is designed to render that vote moot before the membership arithmetic shifts again.
Short term · High
Consequence
Hegseth's Article 2 testimony makes it politically impossible for Republican senators to file an AUMF, removing the only legislative vehicle that would constrain the administration while also authorising the war.

Source Landscape

This story draws on centre-left-leaning sources from United States

United States

Primary parallel: The Nixon administration's 1970 Cambodia campaign offers the closest rename-and-reset precedent. After the 1964 Gulf of Tonkin Resolution was invoked for Vietnam, Nixon rebranded Cambodian operations as distinct from the Vietnam authorization, arguing each country required separate legal justification.

The 1973 Congress, sceptical of this framing, wrote the WPR partly to prevent exactly this kind of geographic or operational rebrand from resetting accountability clocks. The Sledgehammer rename repeats the Nixon structure: a new name for what is operationally the same campaign.

Counter-parallel: The 1989 Panama 'Operation Just Cause' created a genuine precedent for a named operation outside an existing authorisation framework, but the 48-hour WPR notification was filed on time and Congress chose not to invoke the 60-day clock.

The Administration is hoping Sledgehammer can mimic the Just Cause pattern, where political momentum and rapid success pre-empted the legal dispute. The Iran conflict, at 80+ days with no conclusion visible, lacks the operational closure that made Just Cause's clock moot.

Consensus view: The Lawfare Institute's national security law team and the American Bar Association's Standing Committee on Law and National Security both assess the rename strategy as legally novel but substantively weak.

The War Powers Resolution's 60-day clock attaches to 'hostilities', not to the name of an operation; renaming EPIC FURY as Sledgehammer while continuing the same naval blockade and air campaign does not restart the statutory clock under any reading endorsed by the statute's legislative history or the 1973 Senate debate. Brookings Institution senior fellow Benjamin Wittes has noted the argument resembles the Bush-era OLC 'enhanced interrogation' redefinition: a label change attempting to override a statutory category.

Counter-view: The Trump administration's Justice Department Office of Legal Counsel, following the precedent of Jay Bybee's 2002 'torture memo' methodology, is expected to argue that 'hostilities' under the WPR requires an active and continuous commitment of forces, and that a named pause between EPIC FURY and Sledgehammer creates a legal discontinuity the clock cannot bridge.

Georgetown Law's Rosa Brooks, author of the leading WPR academic commentary, has called this approach 'operationally dishonest but legally arguable in front of a sympathetic court'.

Key tension: Whether any federal court will grant standing to the House or Senate to challenge the rename, given the Supreme Court's historical reluctance to adjudicate war powers disputes as nonjusticiable political questions.

Different Perspectives

French Football Federation

The FFF called an 11:00 CEST press conference for 28 July, at its Paris headquarters, following an extraordinary executive committee meeting, at which Zinedine Zidane is expected to be presented as head coach succeeding Didier Deschamps. As of this writing no communique confirms the appointment, contract length or start date.

Morocco

Morocco is pushing for the 2030 final at its Grand Stade Hassan II in Casablanca, a planned 115,000-seat venue that would be the world's largest football stadium on completion. The venue is contested by a Spanish petition for the Santiago Bernabeu, and FIFA has fixed neither the venue nor the tournament's proposed 64-team format.

FIFA

FIFA's first tournament report, published 27 July, itemises nearly 300,000 accredited personnel, 73,700 security staff and 300,000 square metres of custom-grown turf, with no revenue or cost figure attached. As a Swiss association answering to its own Congress rather than a treasury, FIFA has followed the same operational-before-financial sequence it used after Qatar 2022.

Javier Tebas / La Liga

La Liga president Javier Tebas said on 21 July that FIFA's system is rotten from the root and that Gianni Infantino's time as president has, in his words, concluded. Tebas has no vote in FIFA's process, so days after the IOC declined jurisdiction over a separate ethics complaint, he used the only instrument he has.

Mexico City government

Head of government Clara Brugada presented a closing report on 22 July crediting the tournament with 44 billion pesos of economic activity, 2,000-plus accelerated public works and 100,000 formal jobs in June alone. The city has not published the method behind that figure, and three other Mexican bodies count the same five weeks differently.

Town of Foxborough

Foxborough answered Kraft Group's June lawsuit on 7 July with a 61-page counterclaim, calling the stadium's owners 'a collection of multibillion-dollar corporations' trying to shift its $7.8 million security bill onto taxpayers. The town says its licensing power and its billing power run through the same board, and it wants the court to award its own costs too.
