The Lawfare Podcast: Lawfare Daily – The 2026 National Defense Authorization Act

Date: December 29, 2025
Host: Ariane Tabatabai, with Lauren Boss and Scott Anderson

Episode Overview

This episode provides a deep dive into the Fiscal Year 2026 National Defense Authorization Act (NDAA), analyzing its key provisions, highlighting continuities and changes from previous years, and assessing where the law aligns — or collides — with current U.S. national security strategy. Panelists Ariane Tabatabai, Lauren Boss, and Scott Anderson discuss congressional priorities, oversight shifts, operational authorities, and what the inclusion and omission of certain measures signal about the defense policy environment at the dawn of 2026.

Main Themes and Purpose

• Congressional vs. Administration Priorities: The NDAA reveals tension between congressional intent to maintain or expand bureaucracy and executive efforts to streamline.
• Strategic Realignment: The Act’s framing departs somewhat from current national security strategy, signaling a more classical view of great-power competition.
• Oversight Expansion: Notable for both new and strengthened oversight, notification, and reporting requirements, reflecting congressional concerns about executive branch opacity.
• Critical Provisions and Implications: Deep focus on posture in Europe/Asia, support for Ukraine and Taiwan, domestic military support, and repeal of outdated Authorizations for Use of Military Force (AUMFs).
• Omissions and Gaps: Highlights on what reform proposals failed to make it into law, especially on domestic military deployments and organizational reform.

Key Discussion Points and Insights

1. Congressional Turf and Bureaucracy (04:00–10:00)

• Growth vs. Streamlining: A notable tension exists between executive efforts to “shrink the bureaucracy” and Congress’s tradition of creating new positions and offices within the defense establishment.
  • “One thing we haven’t talked about too much ... is that Congress has actually played a huge role in adding to them.” – Ariane (05:30)
• Examples: Creation of a new Assistant Secretary of Defense post for International Armaments Cooperation, new leadership for Foreign Military Sales information, and a defense industrial base integration program.
• Pipelines Retained: Congress preserves talent pipelines (Wrangell, Payne, Pickering, and Veterans Innovations Fellowships) despite executive attempts to cut them.

2. Strategic Disconnect & Framing (07:20–15:00)

• Divergence from Administration: The 2026 NDAA adopts an adversary-centered framing more in line with prior security strategies, emphasizing threats from Russia, China, North Korea (DPRK), and Iran.
• Congressional Reassertion: Though some interpret this as Congress reclaiming national security policymaking, panelists caution on over-reading the degree of reassertion.
  • “This NDAA does not align with the national security strategy … I, but I’m not surprised. This is what I expected.” – Lauren (08:09)
• Neglect of Western Hemisphere: The NDAA omits focus on administration-favored regions, particularly Western Hemisphere operations.

3. Geographic and Operational Provisions (15:19–26:00)

Europe

• Troop Presence Safeguards:
  • Prohibits unilateral reductions in U.S. posture or dropping U.S. leadership in NATO Supreme Allied Command Europe (SACEUR) without advance, public certification by career military officials (18:27).
  • “What they say is … you have to give us 60 days’ notice … and that includes a certification by a career military official.” – Scott (18:27)
• Ukraine:
  • Extension of security initiative to 2028, though overall funding ($400 million) is lower than past years.

Indo-Pacific

• Strategic Competition: Strong language on “strengthening partnerships,” explicit calls to include Taiwan in Rim of the Pacific exercises, enhanced cooperation with the Philippines, co-development programs, and defense industrial base links with allies.
  • “Some of the language, especially for the Indo-Pacific, was a little bit more tactical and directive than we’ve seen before.” – Lauren (23:28)

Middle East / CENTCOM

• Integrated Missile Defense: Provision continues for air/missile defense, particularly for Israel and regional partners.
• Drone Lessons: Funding to capture counter-UAS lessons learned.

4. Congressional Oversight and Transparency (26:00–47:00)

Senior Military Removals (27:00)

• New notification and justification requirements upon removal of JAGs, Joint Chiefs, or Combatant Commanders. Though Congress cannot block removals, transparency is increased, reflecting bipartisan concern over politicization or bias in firings.
  • “There is really just this desire for transparency in these cases. A lot of these removals came with no official statement on why.” – Lauren (27:00)

Domestic Deployments (31:19)

• Markings and Training: Enhanced requirements for clear identification of military personnel supporting civil authorities and for pre-deployment training on law of armed conflict and domestic support protocols.
• Immigration Support Oversight: New reporting on DoD aircraft used for deportations, total aliens held on military installations, and DoD support for immigration enforcement.
• Notably missing: Major Posse Comitatus reform or Insurrection Act amendments did not make the final NDAA.

Boat Strikes in the Caribbean (37:14)

• Executive’s ability to launch “boat strikes” constrained by new requirement: 75% cap on Secretary of Defense’s travel fund use unless DoD releases unedited strike videos.
  • "Unless you provide unedited video … you can’t spend more than 75% of travel funds made available to you.” – Scott (37:50)
• Applies also to “execute order” and legal/policy framework reports, holding back funds until reporting is complete.

Sensitive Military Ops and Autonomous Weapons (41:47)

• Expanded notification requirements if sensitive military operations fail, and for waivers of DoD autonomous weapons restrictions.
• Legal reviews of all waivers must be provided to Congress, raising the profile of AI, autonomy, and law-of-armed-conflict concerns.

5. AUMF Repeals (47:19–51:41)

• The NDAA repeals the 1991 and 2002 Iraq AUMFs, formally ending congressional authorizations for the Iraq wars.
  • "It actually does shut down a peripheral authority ... if Executive branch wants to pursue a major campaign ... it’s going to have to come back to Congress now." – Scott (47:44)
• Signals movement for greater congressional control on war powers, though the 2001 AUMF remains a future debate.

6. Other Notable Provisions (52:20)

• Syria Sanctions: Repeal of Caesar Act sanctions, to support Syrian economic recovery in the post-Assad era.
• “Golden Dome” Defense: Launch of Trump administration’s new national missile defense system.
• Outbound Investment Restrictions: New statutory authority restricting and even unwinding U.S. investments in sensitive tech sectors (AI, quantum, semiconductors) in China, Russia, Iran, etc.—testing novel constitutional boundaries.

7. What's Missing? (57:42–61:54)

• Domestic Military Law: No reforms to Posse Comitatus, Insurrection Act, or clarity on use of the military for domestic law enforcement despite numerous proposals and ongoing legal ambiguities.
• Space Force: Less content on space operations and capabilities than expected.
• Appropriations and Bureaucracy Reform: Little movement on congressional authority over reorganization or executive efforts to restructure agencies.

Notable Quotes & Memorable Moments

• “This change will specifically say now, anytime military is on the ground supporting civil authorities, ... they must mark their military branch.” – Lauren, [31:19]
• "I think there are more concerns on a bipartisan basis of how the military might be used abroad … and so I see this as ... Congress trying to reassert that role and at least take these two AUMFs off the table going forward.” – Lauren, [50:56]
• "Congress is staying on top of these issues. And it’s not just about the boat strike videos … it's actually about a whole universe of other reports that this administration does not seem to be providing.” – Scott, [37:50]
• “If you’re going to waive [autonomous weapons restrictions] ... you have to notify Congress before you do that ... and provide a ratification explanation.” – Scott, [41:47]
• “I would have loved to see more focus on [domestic deployment reform], ... huge legal ambiguities that we have yet to close.” – Lauren, [57:57]

Final Thoughts

The 2026 NDAA reflects a Congress intent on retaining substantial input into national security policy, often pulling policy in more traditional, hawkish directions than those favored by the present administration. It features significant new reporting, oversight, and checks, particularly in areas where recent events have sparked bipartisan anxiety. However, some ambitious legal reforms—especially regarding military involvement in domestic affairs—remain unrealized, and the push-and-pull between congressional guidance and executive initiative appears poised to continue into 2027 and beyond.
