FY 2026 NDAA Repeals 1991 and 2002 Iraq AUMFs — First War-Authorization Repeal Since 1971 Serves as Cover for Capture-Relevant Bundle

The FY 2026 National Defense Authorization Act, signed December 18, 2025, included the Kaine-Young bipartisan provision repealing the 1991 and 2002 Authorizations for Use of Military Force against Iraq. This is the first congressional clawback of a war authorization since the 1971 repeal of the Gulf of Tonkin Resolution. The provision’s substantive content is important in its own right, but its placement in the FY 2026 NDAA bundle also served a specific procedural function: it provided political cover for the broader bundle of capture-relevant provisions (Caesar Act repeal, Section 8366 nuclear export working group, Section 1085 AUKUS oversight reduction, Sections 1651-1652 Golden Dome codification).

What the AUMF Repeal Does

• Repeals Authorization for Use of Military Force Against Iraq Resolution of 1991 (Pub. L. 102-1) — authorizing the Gulf War
• Repeals Authorization for Use of Military Force Against Iraq Resolution of 2002 (Pub. L. 107-243) — authorizing the Iraq War
• Does not repeal the 2001 AUMF (against those responsible for 9/11 and associated forces), which remains the principal operational legal basis for ongoing U.S. counterterrorism operations in multiple theaters

Legislative History

Senators Tim Kaine (D-VA) and Todd Young (R-IN) first introduced the AUMF repeal bill in 2019. The House voted to repeal both AUMFs in June 2021. The Senate voted to repeal both in March 2023. Because the votes occurred in different Congresses, the legislation did not become law — by parliamentary rule, repeal requires both chambers to act in the same Congress. The Senate passed the standalone Kaine-Young bill (S.1499) on October 10, 2025 by bipartisan margin; the House then adopted the provision via conference inclusion in the FY 2026 NDAA; the combined vehicle became law on December 18.

Why the Bundle Placement Matters

Kaine and Young’s provision is substantively a war-powers-reclamation step celebrated across the left-leaning war-skeptic coalition, the libertarian right, and a narrow but active Senate Foreign Relations Committee bipartisan bloc. Its inclusion in the FY 2026 NDAA provides three specific political functions:

1. Headline positioning: The “first AUMF repeal since 1971” frame dominated the left and libertarian coverage of the NDAA bundle, displacing coverage of Sections 8369 (Caesar), 8366 (nuclear export), and 1085 (AUKUS).
2. Caucus management: Members of the Congressional Progressive Caucus and the House Liberty Caucus — who might otherwise have voted against the NDAA on grounds of the Golden Dome codification, the Outbound Investment Security Program expansion, or the Israel funding — could point to the AUMF repeal as their yes-vote justification.
3. Sponsorship distribution: Kaine (SFRC Ranking Member, D-VA) is the leading Senate Democratic voice on war powers; his sponsorship of the AUMF repeal signals Democratic cover for the broader conference package. Young (R-IN) similarly signals to Republicans that a hawkish bloc member is comfortable with the package.

Broader Context

The 2002 AUMF has been cited as legal authority for military operations beyond Iraq — including against ISIS in Syria and Iraq, for some Quds Force operations, and in arguments over the January 2020 Soleimani strike. Its repeal is substantively meaningful. But its repeal does not constrain the Trump administration’s current operational authorities, which rest on the 2001 AUMF, Article II self-defense claims, and the Operation Southern Spear Venezuela counter-narcotics framing (see 2025-12-15–operation-southern-spear-death-toll-82-killed).

The simultaneous FY 2026 NDAA also included Hegseth boat-strike oversight provisions (see 2025-12-17–senate-passes-ndaa-hegseth-boat-strike-oversight) — another oversight-win provision that coexists with the AUMF repeal to further the “Congress is reclaiming war powers” framing while the bundle’s more substantively significant capture provisions advance.

Why This Event Matters (Structurally)

This entry is included in the NDAA-bundling capture-template documentation not because the AUMF repeal is itself a capture event — it is not — but because the NDAA-bundling template requires cover provisions that provide left-coded and libertarian-coded wins to secure the narrow political margins for capture-provision bundles. The Kaine-Young AUMF repeal is the clearest cover provision in the FY 2026 NDAA. Future NDAA bundles will include analogous cover provisions; identifying them in advance is part of the anti-capture analytical toolkit.

Research Gaps

• Roll Call December 24, 2025 reporting on the specific sequencing of AUMF-repeal provisions in the conference report
• Whether the conference committee considered and rejected additional war-powers provisions (2001 AUMF sunsetting, Syria AUMF repeal) as too politically risky
• Specific members whose NDAA vote was attributed in their public statements to the AUMF-repeal inclusion
• Whether any Trump administration executive-action equivalent exists that would partially restore the repealed authorities
