Pete Hegseth Testifies Iran's Nuclear Facilities ‘Obliterated' Before War

Defense Secretary Pete Hegseth told lawmakers Wednesday that Iran's nuclear facilities had been "obliterated," triggering sharp pushback during a House Armed Services Committee hearing.

The exchange highlighted questions about the administration's justification for the conflict, which it said was aimed at stopping an imminent nuclear threat.

Wednesday’s clashes could intensify congressional scrutiny of the conflict's costs, strategy and legality as lawmakers weigh future funding and oversight.

Democratic Representative Adam Smith of Washington pressed Hegseth on why the U.S. went to war if Iran's nuclear program had already been destroyed, prompting Hegseth to argue that Tehran had not abandoned its nuclear ambitions. The hearing, nominally focused on the Pentagon's proposed 2027 budget, quickly became a confrontation over the conduct of the war, which was launched without congressional authorization and has cost an estimated $25 billion.

Why are Pete Hegseth and Dan Caine Testifying?

Hegseth and Joint Chiefs Chairman Gen. Dan Caine are testifying before Congress this week as part of hearings on the Trump administration's proposed 2027 defense budget, which would increase Pentagon spending to a record $1.5 trillion. The House Armed Services Committee hearing is focused on military readiness, weapons procurement and long‑term strategy.

The testimony comes as lawmakers intensify scrutiny of the U.S. war with Iran, launched in February without congressional authorization and now estimated to have cost $25 billion. Members of both parties are pressing Hegseth and Caine for clarity on the conflict's objectives, results and strain on U.S. forces and munitions.

Democrats have questioned civilian casualties, the depletion of critical weapons stockpiles and Iran's ability to penetrate U.S. defenses with drone attacks that killed or wounded American troops. A fragile ceasefire is in place, but the broader military and political endgame remains unclear.

Hegseth is also facing bipartisan unease over changes to Pentagon leadership, while Caine is expected to address the operational impact amid a heightened war posture. Lawmakers are using the hearings to assess both wartime decision‑making and the military's preparedness going forward.

What Lawmakers Challenged Hegseth and Caine On

Democratic lawmakers repeatedly challenged Hegseth over his description of Iran's nuclear program, zeroing in on an exchange in which he said Tehran's nuclear facilities had been "obliterated." Smith, the committee's top Democrat, pressed Hegseth on how that claim squared with the administration's assertion that the war was necessary to stop an imminent nuclear threat.

"Whoa, whoa, whoa," Smith said, questioning why the U.S. would initiate a war if Iran's nuclear program had already been destroyed. Hegseth responded that Iran had not abandoned its nuclear ambitions, arguing that intent - not just physical facilities - justified the military action.

Lawmakers also confronted the Pentagon over the mounting costs of the conflict and the strain on U.S. military resources. Pentagon officials told the committee the war has already cost about $25 billion, much of it spent on munitions, as lawmakers warned about depleted stockpiles and readiness concerns.

Other Democrats raised civilian casualty reports, including the bombing of a school, and questioned how Iranian drone swarms were able to penetrate U.S. defenses, killing or wounding American troops. Smith warned against what he described as a broader strategy of coercion and force, saying, "You can win a whole lot of little small battles and lose the war."

Hegseth pushed back forcefully, saying skepticism from lawmakers was undermining the military effort. "The biggest challenge, the biggest adversary we face at this point are the reckless, feckless and defeatist words of congressional Democrats and some Republicans," he said, as Caine sat beside him during the contentious hearing.
