Title

Senate Armed Services examines the 2026 National Defense Strategy and Iran strikes

Purpose

The Senate Armed Services Committee convened to receive testimony from Under Secretary of Defense for Policy Elbridge Colby on the 2026 National Defense Strategy (NDS), covering its treatment of China, Russia, Taiwan, allied burden-sharing, and the defense industrial base. The hearing occurred amid a live U.S. military operation against Iran ("Operation Epic Fury"/"Midnight Hammer"), so most member questioning focused on the legality, objectives, and justification for that conflict rather than the strategy document itself. A closed session with Colby was scheduled to follow. Begins at▶ 0:45:32

Who spoke

• Chair Roger Wicker (R-MS)▶ 0:46:04: Opened by praising the NDS's China focus but criticized it for ignoring the "axis of aggressors" acting in concert▶ 0:48:42, downplaying Russia and Ukraine▶ 0:50:37, omitting Taiwan by name in favor of "first island chain" language▶ 0:53:22, and being nearly silent on nuclear weapons▶ 0:54:22; later pressed Colby on unobligated Taiwan security funds▶ 1:16:03 and enforced a strict five-minute rule▶ 1:15:34.

• Sen. Jack Reed (D-RI), Ranking Member▶ 0:56:11: Called the NDS "already obsolete" given the Iran operation▶ 0:56:39, criticized its partisan tone▶ 0:59:02, asked what a "decent peace" with China would forgo militarily▶ 1:00:47, and argued the document's promise to end "interventionism, endless wars, regime change" contradicts current operations in Iran, Venezuela, Syria, and Somalia▶ 1:03:59.

• Sec. Elbridge Colby, Under Secretary of Defense for Policy▶ 1:05:05: Described the NDS's four pillars — homeland defense, Indo-Pacific denial along the first island chain, allied burden-sharing, and supercharging the defense industrial base▶ 1:07:55; said the campaign against Iran targets its missile forces and navy, not necessarily regime change, though he called it a "historic opportunity" for Iranians to act▶ 1:24:54; repeatedly deferred to legal counsel on the operation's legal basis▶ 1:56:46.

• Sen. Deb Fischer (R-NE)▶ 1:26:28: Pressed on munitions production bottlenecks and total munitions requirements▶ 1:26:58, and asked whether the administration plans a formal Nuclear Posture Review, which Colby said is not planned▶ 1:30:41.

• Sen. Jeanne Shaheen (D-NH)▶ 1:31:29: Quoted Colby's past writings questioning strikes on Iran without a clear strategy and noted his opening statement omitted Ukraine▶ 1:33:43; argued more pressure on Russia, not less, is needed for peace▶ 1:35:07.

• Sen. Mike Rounds (R-SD)▶ 1:36:40: Asked about the "simultaneity problem" of multiple adversaries acting at once and whether the department has shared specific resource shortfalls with Congress▶ 1:40:24.

• Sen. Tim Kaine (D-VA), first appearance▶ 1:41:34: Asked why the administration struck Iran now given no imminent-threat evidence, questioning whether the U.S. has effectively "delegated" the war decision to Israel's prime minister▶ 1:42:02; also warned the strikes could raise false hopes among Iranian civilians unable to be protected from the ground▶ 1:45:18.

• Sen. Rick Scott (R-FL)▶ 1:46:48: Praised Trump's "decisive leadership" in the Iran operation and thanked service members▶ 1:47:15; raised complaints from allies that the Department of War is slow-walking weapons sales and training requests▶ 1:50:24.

• Sen. Gary Peters (D-MI) [2:12:32... actually 1:52:32]: Argued Congress, not the president, holds war-declaration power under Article I▶ 1:52:45, noted rising domestic costs, and pressed Colby on whether Trump has articulated a clear purpose and end state for the Iran campaign given Colby's own past writings urging reduced military focus on Iran▶ 1:55:41.

• Sen. Markwayne Mullin (R-OK)▶ 1:58:03: Defended Trump's withdrawal from the Iran nuclear deal and the strikes, contrasted them with past Democratic-led interventions in Syria and Libya▶ 1:58:22, and asked Colby about strategy toward Russia and Canada▶ 2:02:17.

• Sen. Elizabeth Warren (D-MA)▶ 2:03:36: Got Colby to confirm that Congress, not the president, declares war under the Constitution▶ 2:04:23; pressed him line-by-line on whether the Iran operation constitutes the "interventionism," "endless wars," and "regime change" the NDS says it will avoid▶ 2:06:38.

• Sen. Eric Schmitt (R-MO)▶ 2:08:50: Praised the NDS's realism and argued allies had been "free-riding" on U.S. defense spending for decades▶ 2:09:39; asked how Colby communicates burden-sharing expectations to European allies▶ 2:10:31.

• Sen. Mark Kelly (D-AZ)▶ 2:13:59: Pressed Colby on the contradiction between the NDS downgrading the Middle East as a core theater and the administration's current framing of Iran as an imminent homeland threat▶ 2:14:36, and noted Trump previously said Iran's nuclear program was "obliterated" before the new strikes began▶ 2:17:39.

• Sen. Jim Banks (R-IN)▶ 2:19:28: Asked how securing the Western Hemisphere (Panama, Venezuela) supports Indo-Pacific power projection▶ 2:19:50 and how a weakened Iran could free up assets for the Indo-Pacific▶ 2:21:11.

• Sen. Tim Kaine (D-VA), second round▶ 2:24:34: Cited over 14,000 U.S. troop deaths and $8.2 trillion in war costs since the Iraq/Afghanistan era▶ 2:25:05, and pressed Colby to acknowledge that killing Iran's supreme leader and pursuing Maduro's arrest constitute "regime change" contrary to the NDS's stated goals▶ 2:28:30.

• Sen. Dan Sullivan (R-AK)▶ 2:29:51: Argued Iran has effectively been at war with the U.S. for decades, citing the 1983 Beirut bombing and a 2024 briefing in which the FBI director confirmed Iran was still trying to kill Trump▶ 2:31:48; asked about U.S. munitions stockpile messaging to adversaries▶ 2:33:19.

• Sen. Kirsten Gillibrand (D-NY)▶ 2:35:26: Argued Trump has given mixed, shifting justifications for the Iran operation (regime change vs. missiles vs. centrifuges) and that he should seek an Authorization for Use of Military Force from Congress▶ 2:37:18.

• Sen. Jacky Rosen (D-NV)▶ 2:40:20: Expressed concern about lack of clear objectives and congressional authorization for the Iran campaign▶ 2:41:06, then pivoted to ask why the NDS gives cyber capabilities so little emphasis▶ 2:42:24 and about the U.S. withdrawal from bases in northeastern Syria amid ISIS threats▶ 2:44:23.

• Sen. Tammy Duckworth (D-IL)▶ 2:45:48: Called the Iran campaign illegal and criticized the administration's broader pattern of military actions in Venezuela, the Caribbean, and against NATO allies▶ 2:46:13; pressed Colby on Indo-Pacific contingency planning, citing over 750,000 Americans living in the Philippines and the South China Sea's role in one-third of global maritime trade▶ 2:48:47.

Key moments

• Colby confirmed under direct questioning from Sen. Warren that under the Constitution, Congress — not the president — holds the power to declare war▶ 2:04:32.

• Sen. Kaine forced Colby to acknowledge, after repeated deflection, that the NDS's own approval process meant the Secretary of War and President signed off on language pledging to avoid "interventionism, endless wars, regime change, and nationbuilding"▶ 2:27:24, then argued the killing of Iran's supreme leader and the operation against Venezuela's Maduro contradict that pledge▶ 2:28:30.

• Sen. Kelly noted that Trump previously declared Iran's nuclear program "obliterated," yet the administration launched a new war days later on the premise of an imminent nuclear/missile threat — Colby could not confirm Iran had missiles capable of reaching the U.S. homeland▶ 2:17:39▶ 2:16:31.

• Chair Wicker cited "thousands" of authorized and appropriated Taiwan security funds that appear unobligated; Colby said he could not give an informed answer and would follow up▶ 1:16:34▶ 1:17:24.

• Sen. Reed noted the NDS states allies should "take primary responsibility" for regional defense against Iran, yet the U.S. just launched its largest military campaign since the 2003 Iraq invasion without clarity on whether allies were even notified in advance▶ 1:03:29▶ 1:23:11.

• Sen. Mullin and Sen. Kaine sparred by proxy over historical precedent — Mullin cited Obama-era strikes in Syria/Libya/Pakistan without congressional authorization▶ 1:58:22, while Kaine (after Mullin left) countered that Democrats forced Obama to seek congressional approval for Syria action in 2013▶ 2:26:03.

• Colby said FMS (foreign military sales) demand has "quadrupled since 2021," which he called "an excellent problem rather than a bad problem," pointing to consolidation of the process under Under Secretary Duffy▶ 1:52:04.

• Sen. Rosen highlighted that the NDS only sparingly mentions cyber capabilities despite cyber's growing centrality to warfare; Colby rejected the characterization, citing work by Assistant Secretary Sutton and General Hartman▶ 2:42:24▶ 2:43:15.

• Six U.S. service members were reported killed in the Iran operation as of the hearing, cited by multiple senators including Warren and Kaine▶ 2:03:52▶ 2:26:54.

• Colby stated the campaign's core military objectives are degrading Iran's ballistic missile force, one-way-attack drone capability, and navy, and preventing a nuclear weapon — while separately noting the President has encouraged the Iranian people to "take this opportunity" to overthrow the regime▶ 1:24:21▶ 1:24:54▶ 1:46:01.
