Hegseth Faces Senate Questions on Iran War Strategy and Exit Path

US Secretary of Defense Pete Hegseth faced sharp questions from senators of both parties Thursday as he testified before the Senate Armed Services Committee — his first appearance before Congress since the Iran war began in January 2026. The hearing, scheduled for three hours, ran closer to five as lawmakers demanded specifics on the administration's war objectives, the criteria for victory, and the potential endgame for what is now the longest US military engagement in the Middle East since the Iraq war.

At the heart of the questioning was a simple but unanswered question: what does winning look like? According to AP News, Hegseth outlined a strategy built on three pillars — maximum pressure on Iran's oil revenues through the naval blockade of the Strait of Hormuz, degradation of Iran's nuclear program through targeted strikes, and containment of the conflict to prevent it from spreading to US allies in the Gulf. But senators from both parties pressed him on what each pillar's success metric actually was, and the answers they received were long on framework and short on specifics.

The Definition of Victory

Senator Jack Reed of Rhode Island, the committee's ranking Democrat, asked Hegseth directly: "If Iran agrees tomorrow to stop enriching uranium above 3.67 percent, dismantle its ballistic missile program, and sever ties with Hezbollah and the Houthis — does the war end?" According to a transcript of the exchange reported by AP News, Hegseth responded that "complete, verifiable, irreversible denuclearization" would be the US condition for ending operations — a standard that analysts note Iran has historically refused to meet under any circumstances, including during the JCPOA negotiations that produced the 2015 nuclear deal.

Republican senators, while more supportive of the administration's overall approach, pushed for clarity on the exit timeline. Senator Joni Ernst of Iowa asked whether the Pentagon had modeled scenarios in which the Iran war extends beyond 12 months, and what the implications would be for US military readiness in the Indo-Pacific, where China-watchers have grown increasingly concerned that prolonged Middle East deployments could weaken the US strategic posture. Hegseth said the Pentagon had conducted such modeling but declined to share specifics in an unclassified setting, citing operational security concerns.

The Cost of the Iran War

The committee also received testimony from the nonpartisan Congressional Budget Office, which presented estimates on the cost of the conflict. According to the CBO figures cited by Reuters, the direct military cost of the Iran war through April 2026 stands at approximately $47 billion — covering drone strikes, carrier group operations, SEAL team deployments, and the logistics of maintaining the Hormuz blockade. The figures did not include the downstream costs of higher gasoline prices for American consumers, which the Energy Information Administration estimates adds up to roughly $800 per household annually at current oil price levels. The total economic cost — including higher energy prices, supply chain disruptions, and the macroeconomic impact of oil shocks on trading partners — is estimated by the IMF to be several times larger.

Hegseth acknowledged that the blockade was having "significant effects" on Iranian oil exports but declined to characterize them as decisive. When Senator Elizabeth Warren of Massachusetts pressed him on whether economic strangulation alone would force Tehran to capitulate — a theory some administration officials have privately floated — Hegseth was careful in his response. According to the AP, he said the goal was "behavior change, not regime change," a distinction that seemed to satisfy few members of the committee and that critics argue amounts to the same outcome without the political liability.

Regional Spillover and Alliance Tensions

Perhaps the most urgent line of questioning came from senators representing states with large Muslim and Arab American populations, including Michigan's Debbie Dingell and Minnesota's Amy Klobuchar. Both asked about reports that the Iran war had increased tensions with Iraq's government, which has been forced to navigate between maintaining security ties with the United States and managing domestic political pressure from Shia political parties with long-standing connections to Tehran. According to the Pentagon's own recent testimony to the Senate Foreign Relations Committee, cited by Reuters, there have been at least 14 incidents of Iran-backed militia groups in Iraq targeting US personnel or bases since January.

Senator Tim Kaine of Virginia raised a structural concern: whether the Iran war was constitutional without a formal congressional authorization. Hegseth argued that the 2001 Authorization for Use of Military Force, combined with inherent executive branch authority to protect US personnel and interests, provided sufficient legal basis — a position that the Congressional Research Service has disputed in recent analysis, according to committee staff.

The hearing ended without any bipartisan agreement on war powers authorization or timeline — an outcome that surprised few observers given the deep partisan divide on Middle East military interventions. What it did make clear is that the Iran war will remain a central congressional fight for the foreseeable future, with or without a clear exit strategy from the executive branch, and that the administration's three-pillar framework leaves more questions unanswered than it resolves.
