Senate Panel Grills Pentagon on National Defense Strategy as Iran War Reshapes U.S. Military Priorities

Why it matters

The Senate Armed Services Committee convened on March 3, 2026, to examine the Trump administration's National Defense Strategy — a document that explicitly deprioritized the Middle East — just days after the U.S. launched military strikes against Iran. The collision between strategy and reality produced sharp bipartisan questioning of Under Secretary of Defense for Policy Elbridge Colby, who defended the Pentagon's "flexible realism" while senators from both parties challenged whether the framework can survive contact with an active war. The hearing was immediately followed by a classified session in SVC-217.

The big picture

The 2026 National Defense Strategy, released January 23, represented a fundamental reordering of U.S. defense priorities. It placed homeland defense and the Western Hemisphere first, followed by deterring China, while explicitly accepting "greater risk in secondary and tertiary theatres" — including Europe and the Middle East.

Then came Operation Epic Fury. On February 28, the U.S. and Israel launched joint strikes against Iran. By the day of the hearing, six U.S. service members had been killed, and President Trump said operations could last "far longer" than a month.

That backdrop turned what might have been a routine defense strategy hearing into a pressure test for the administration's entire strategic framework. The House Armed Services Committee scheduled its own hearing on the same topic two days later, signaling sustained bicameral scrutiny.

Think tanks had already flagged concerns. The Atlas Institute warned that the NDS "reflects an institutionalizing of risk acceptance in secondary and tertiary theatres as an explicit policy choice." DefenseScoop noted the strategy "barely mentions technology" — a sharp departure from 2018 and 2022 predecessors that treated AI and hypersonics as cornerstones of military dominance.

What they're saying

The hearing exposed fault lines within the Republican majority and between parties.

Sen. Roger Wicker (R-MS), the committee chair, praised elements of the NDS but fired a pointed shot at the administration's Ukraine posture. In his opening statement, Wicker said: "I do not see a concerted strategy to get new types of weapons to Ukraine." The Hill reported that Wicker criticized the NDS's treatment of Russia, Ukraine, and the Middle East — a notable rebuke from a GOP chairman directed at a GOP administration.

Colby pushed back with measured language. "We recognize our interests in Europe," he told Wicker, according to Breaking Defense. "The basic logic here, senator, is not to ignore or downplay."

Democrats were more aggressive. Jewish Insider reported that "a parade of Democratic senators pressed" Colby on the Iran war, "criticizing the campaign and its execution without congressional authorization." Senators questioned Secretary of State Marco Rubio's justification for preemptive strikes — that the U.S. struck because "we knew that if Iran was attacked... they would immediately come after us."

USNI News characterized Colby's approach as "flexible realism," with the under secretary arguing the U.S. military "cannot operate everywhere."

Colby also told Sen. Deb Fischer (R-NE) that the strategy "is designed to move the bureaucracy and the organization in a certain direction" — an acknowledgment that the NDS is as much an internal management tool as a strategic document.

Political stakes

For the administration

The Trump White House faces a credibility gap. Its NDS deprioritized the Middle East weeks before launching a war there. Defense Secretary Pete Hegseth insisted Operation Epic Fury is "not a so-called regime change war," but Trump's own statements about eliminating Iran's nuclear program and potentially deploying ground troops complicate that framing.

For the committee chair

Wicker occupies a delicate position. He is a Republican ally of the administration but has staked his chairmanship on a defense buildup that exceeds what the NDS envisions. His 2026 priorities call for "broadening the use of private capital in defense manufacturing" and passing "the next phase of defense investments." The NDS hearing feeds directly into the FY2027 NDAA markup, where Wicker will need to reconcile the administration's strategy with his own ambitions.

For Democrats

Sen. Jack Reed (D-RI), the ranking member, has pushed for accountability mechanisms. The bipartisan FY2026 NDAA, which passed 77-20, fences 25 percent of the Office of the Secretary of Defense travel budget until the Pentagon delivers a five-year Taiwan Security Assistance Roadmap. Several Democrats on the committee — including Reed, Sen. Jeanne Shaheen (D-NH), and Sen. Tim Kaine (D-VA) — face potential 2026 reelection campaigns where the Iran war could be a defining issue.

Yes, but

The NDS's China-first framework still commands broad bipartisan support in principle. Both parties agree that deterring Beijing along the First Island Chain is a strategic imperative. The FY2026 NDAA fully funded the Pacific Deterrence Initiative and supported the "Golden Dome" missile defense architecture. The disagreement is not over whether to prioritize China — it is over how much risk to accept everywhere else while doing so.

The German Marshall Fund noted that the NDS "reinforces many of the Trump administration's positions articulated over the last year," suggesting the strategy is less a radical break than a codification of shifts already underway.

What's next

  • War Powers clock: If the administration launched Iran strikes without explicit congressional authorization, the 60-day War Powers Resolution window expires in late April 2026, forcing a potential floor vote.
  • FY2027 NDAA markup: The committee will begin crafting the next defense authorization bill this spring. This hearing's testimony will directly shape spending and policy decisions.
  • House hearing: The House Armed Services Committee convened March 5 with the same witness, extending bicameral pressure on the strategy's coherence.
  • Classified follow-up: The closed session in SVC-217 addressed sensitive matters — likely including Iran operational planning and nuclear posture — that will inform committee action behind closed doors.

The bottom line

The administration wrote a defense strategy for one world and is now fighting a war in another — and the Senate Armed Services Committee is not letting that contradiction go unexamined.
