Dear Chairmen Wicker and Rogers and Ranking Members Reed and Smith,

As you enter into conference to resolve the differences between the House-passed version of the National Defense Authorization Act (NDAA) for Fiscal Year 2027 (H.R.8800) and the pending Senate bill (S.4784), We, the undersigned U.S. organizations, strongly urge you to reject the entrenchment of U.S. and Israeli defense collaboration, which goes against U.S. national interests and values, and would expand the risk of U.S. complicity in, and exposure to, human rights violations, war crimes, and genocide.

Specifically, we are deeply concerned by Section 219 in the House NDAA and Section 1217 in the Senate version, which establish a new U.S. Israel Defense Technology Cooperation Initiative aimed at accelerating joint research, development, and integration of Israeli-origin and jointly developed defense technologies into U.S. military systems and programs of record. This would expand U.S-Israeli military integration across some of the most sensitive domains of emerging technology, including quantum computing, AI and autonomous systems, cyber and electronic warfare, directed energy, and defense industrial base co-production, while expediting pathways from R&D into procurement.
