On July 22, the U.S. House of Representatives passed the National Defense Authorization Act (NDAA), Congress' annual defense authorization bill that authorizes funding levels for U.S. military programs and sets policy priorities. While the legislation has historically received broad bipartisan support, this year's debate became a flashpoint over Section 219, a policy provision expanding U.S.-Israel defense technology cooperation. Critics claimed it would "merge" the U.S. and Israeli militaries, while supporters argued it simply strengthens a longstanding strategic partnership.
Here's what the proposal actually does and what it doesn't.
Key Takeaways
- Section 219 is not new security assistance to Israel. It focuses on expanding U.S.-Israel cooperation on defense technology, not increasing annual security assistance.
- The proposal would not merge the U.S. and Israeli militaries. It does not place U.S. forces under Israeli command or vice versa, create a mutual defense treaty, or eliminate either country's independent military decision-making.
- AJC has long maintained that the U.S.-Israel strategic partnership advances American and Israeli security alike. Section 219 builds on decades of cooperation that have benefited both countries through joint defense innovation and shared security.
What Is the NDAA?
The NDAA is Congress' annual defense authorization bill. It sets priorities for the U.S. military and authorizes which defense programs and activities can receive funding.
The NDAA does not actually spend any money. Instead, it sets the rules and authorizes what can be funded. Congress must pass separate spending bills to provide the money.
This is different from U.S. foreign aid to Israel, which is funded through the annual appropriations process. While the NDAA may include provisions that strengthen U.S.-Israel defense cooperation, it is not the bill that provides U.S. security aid to Israel.
This year’s NDAA received an unusually close vote of 216-212, with only six Democrats supporting the bill, although opposition also reflected disagreements over other major provisions, including the Trump Administration’s Iran War strategy.
What are the False and Misleading Claims Being Made About Section 219?
The provision has become one of the most debated parts of this year's NDAA amid broader political disagreements over U.S. support for Israel following Hamas' October 7 massacre of Israelis, the ensuing war in Gaza, and rising tensions with Iran.
Some opponents have falsely claimed Section 219 would effectively "merge" the U.S. and Israeli militaries or integrate the two countries' defense industries. Democrat Rep. Alexandria Ocasio-Cortez (D-NY) said the provision would "merge parts of our military with the IDF," while Republican Rep. Thomas Massie (R-KY) argued the United States should not "merge our military tech and supply chain with Israel's."
Other critics portray Section 219 as a sweeping expansion of the U.S.-Israel defense relationship. The legislation is considerably narrower.
Claim:
Section 219 permanently embeds U.S.-Israel defense cooperation within the Pentagon, making it difficult for future administrations or Congress to change course.
Reality: Section 219 creates a statutory framework for coordinating existing defense technology cooperation, but Congress retains the authority to amend or repeal the law, and future administrations retain discretion over how it is implemented.
Claim:
Section 219 expands the U.S.-Israel relationship beyond traditional military aid.
Reality: The legislation places greater emphasis on defense technology cooperation, but it does not authorize new military aid, create new security guarantees, or fundamentally change the longstanding U.S.-Israel security partnership.
Claim:
Section 219 merges or integrates the U.S. and Israeli defense industries.
Reality: The bill encourages greater cooperation on technologies such as artificial intelligence, cybersecurity, counter-drone systems, and other emerging capabilities. It does not merge the two countries' defense industries, create a joint military, integrate command structures, or require either country to purchase weapons from the other.
What Does Section 219 Actually Do?
Those claims go well beyond what the legislation actually does. Rather than creating a joint military or "merging" the U.S. and Israeli militaries, Section 219 establishes a United States-Israel Defense Technology Cooperation Initiative and directs the Secretary of Defense to designate a senior Department of Defense official—known as an executive agent—to coordinate existing and future U.S.-Israel defense cooperation. The provision does not create a joint military, place U.S. and Israeli forces under shared command, obligate either country to defend the other, or provide new military aid to Israel.
The executive agent would be responsible for:
- Coordinating joint research, development, testing, and evaluation of defense technologies.
- Strengthening cooperation on missile defense, counter-drone systems, cybersecurity, artificial intelligence, and other emerging technologies.
- Improving coordination between the U.S. and Israeli defense industries.
- Identifying opportunities to accelerate the adoption of innovative technologies that benefit both countries.
Many of these areas—including missile defense, cybersecurity, and joint military research—have been part of the U.S.-Israel security relationship for decades. Section 219 primarily formalizes and streamlines existing cooperation rather than creating a new military-to-military relationship.
Rep. Mike Lawler (R-NY) rejected claims that the bill would "merge" the two militaries, noting that the United States routinely cooperates with close allies on intelligence sharing, defense technology, and military exercises. Rep. Brad Schneider (D-IL) has similarly argued that strong U.S.-Israel security cooperation advances both American and Israeli security interests.
Bottom line: Section 219 changes how the Pentagon coordinates U.S.-Israel defense cooperation—not whether that cooperation exists. It does not establish a joint military, place U.S. and Israeli forces under shared command, require either country to fight on the other's behalf, or provide new military aid to Israel.
Why Section 219 is Important for U.S. and Israeli Security:
Closer U.S.-Israel defense cooperation benefits both countries.
It would:
- Help the U.S. military adopt Israeli innovations - often some of the best in the world - more quickly in areas such as missile defense, counter-drone systems, artificial intelligence, cybersecurity, and other emerging technologies.
- Strengthen America's defense industrial base and secure American jobs by encouraging joint research, development, and manufacturing.
- Improve coordination and regional interoperability against shared threats, including Iran and its terrorist proxies.
- Build on decades of successful cooperation that has co-produced technologies benefiting both Israeli and American security.
Is this the Same as U.S. military aid to Israel?
No.
Section 219 is separate from the $3.3 billion in annual U.S. security assistance and $500 million in cooperative missile defense funding Israel receives under the current U.S.-Israel Memorandum of Understanding.
- That assistance is used primarily to purchase U.S.-made defense systems, supporting American defense manufacturers and jobs while helping ensure Israel maintains its Qualitative Military Edge (QME) over potential regional adversaries.
- Section 219 focuses on expanding cooperation in defense technology, research, and industrial partnerships so both countries can more quickly develop and field new military capabilities.
In short, military aid provides funding that comes back to the United States, while Section 219 focuses on collaboration.
AJC's Perspective
AJC has long supported the bipartisan U.S.-Israel strategic partnership because it advances American and Israeli security alike.
AJC believes continued cooperation in missile defense, intelligence sharing, cybersecurity, and defense technology helps both countries address shared threats, particularly from Iran and its terrorist proxies, while driving innovation that benefits both the U.S. military and the Israel Defense Forces. AJC continues to advocate for preserving and strengthening this bipartisan partnership as a cornerstone of American national security and regional stability.
What Happens Next?
The House has passed its version of the NDAA, but the bill is not yet law. The Senate must pass its own version before lawmakers negotiate a final bill that will be sent to the President for signature. The legislation has been procedurally blocked from advancing to the Senate floor due to concerns over Iran policy.
