The final version of the 2026 National Defense Authorization Act negotiated by Senate and House leaders includes a full and unconditional repeal of U.S. sanctions on Syria under the Caesar Civilian Protection Act, as well as a repeal of the war authorizations that allowed for the Iraq war and the first Gulf War.

The Caesar sanctions repeal comes in spite of hesitation from some lawmakers on Capitol Hill, who argued that the sanctions should remain on the books, with relief contingent on the Syrian government meeting various benchmarks. Supporters of full sanctions relief have argued that it’s necessary in order to put Syria on a more predictable and stable financial footing and provide confidence to foreign investors to support reconstruction projects.

Rep. Brian Mast (R-FL), the chairman of the House Foreign Affairs Committee, who had been skeptical of the prospect of unconditional repeal, ultimately decided to provide his approval to include it in the bill.

The legislation requires the administration to report to Congress twice per year to certify whether the Syrian government is complying with a range of U.S. priorities, including cooperating with counter-ISIS efforts, removing foreign fighters from the Syrian government, protecting minority rights, non-aggression toward Israel, integrating the Kurdish-led Syrian Democratic forces, complying with U.S. sanctions, prosecuting human rights abusers and combating narcotics production.

It includes a nonbinding provision that “the president may consider whether to impose targeted sanctions on individuals under existing authorities” if these conditions are not met for two reporting periods, but includes no binding snapback provisions mandating the reimposition of sanctions.

The repeal of the Iraq war authorization has been a longtime priority for lawmakers on both sides of the aisle, but others have argued that a more deliberative approach is needed to ensure that the U.S. maintains its ability to target Iranian proxies or terrorist groups in Iraq.

Largely outside of Middle East policy, the legislation contains a number of provisions seemingly aimed at countering isolationist pushes from within the administration, including provisions to ensure that U.S. aid to Ukraine continues and that the U.S. does not significantly draw down its troop presence in Europe or South Korea.

It also includes a provision seemingly aimed at responding to senators’ public concerns about a lack of transparency and communication by Under Secretary of Defense for Policy Elbridge Colby, mandating that he personally brief Congress twice next year about the national defense strategy.

Overall, the bill proposes a defense budget $8 billion above the Trump administration’s 2026 request — though any actual funding allocations will have to be approved separately through the still-pending appropriations process.

Within the Middle East domain, the NDAA authorizes annual funding for joint missile-defense programs with Israel, including Iron Dome, David’s Sling and Arrow, guaranteed under the memorandum of understanding with Israel that lasts through 2028. 

The explanatory report accompanying the bill requires the administration to brief Congress on Israel’s current Arrow stockpiles — systems that saw heavy use during Iran’s ballistic missile attacks on Israel earlier this year — including potential obstacles to increasing Arrow production capacity and inventory and the possibility of creating “fully redundant Arrow production capacity in the United States.”

Addressing existing regional air- and missile-defense cooperation programs, the report directs the administration to brief Congress on progress toward an integrated air and missile architecture, as well as lessons learned during the past two years of war in the Middle East and the impacts of existing cooperation efforts during that time.

It also requires the Pentagon to brief Congress on any delays in providing aircraft or air-launched munitions to Israel and the “feasibility and advisability” of providing Israel with American systems to fill those gaps in the interim.

The NDAA proposes increasing funding for joint U.S.-Israel anti-tunnelling programs to $80 million, a $30 million increase. The report requires the administration to study potential steps to secure the border between Egypt and Gaza to cut down on smuggling into the enclave via tunnels, drones and the Mediterranean Sea.

The legislation also expands existing U.S.-Israel cooperative programs countering airborne drone threats to include other unmanned systems, including sea- and land-based drones, and proposes funding of $70 million, a $15 million increase.

It extends both the counter-tunnel and counter-drone programs through 2028.

The bill also proposes providing $35 million for a new program to pursue military applications of emerging technologies such as AI, quantum computing and cybersecurity in cooperation with allies like Israel.

The legislation also directs the administration to create a U.S.-Israel Defense Industrial Base Working Group to expand defense production cooperation with Israel, and study the possibility of integrating Israel into the National Technology and Industrial Base, alongside other key U.S. allies.

The explanatory report directs the Defense Department to consider creating a “regional outreach center” of the Defense Innovation Unit in Israel; the House draft of the NDAA had included a requirement that the Pentagon establish such an office.The DIU is a relatively new Pentagon unit with offices around the U.S. that works to allow the military to more quickly adopt emerging commercial technologies.

In an effort to address international boycotts and other punitive measures against Israel, the NDAA requires the administration to continually assess the impact of arms embargoes, sanctions and other restrictions imposed on Israel and the ways the U.S. might be able to mitigate those impacts.

The explanatory report instructs the Pentagon to avoid participating in international arms exhibitions that exclude Israeli companies.

But the final NDAA does not include a provision from the House draft of the bill instructing the administration to engage with top allies to ensure they do not enforce International Criminal Court arrest warrants against the U.S. or Israel.

The report states that the U.S. should engage in “regular military exercises of increasing complexity” with Israel, to include “other regional partners as well when feasible,” and requires the administration to report to Congress on such exercises.

In an effort to address growing cooperation among Iran, China, Russia and North Korea, the legislation instructs the administration to establish a whole-of-government effort to respond to such alliances, including establishing working groups in several Cabinet agencies, charged with providing recommendations to the administration and Congress.

The NDAA expands existing required reports on Iran’s nuclear capabilities, mandating the administration provide additional information to Congress about Iran’s support to its terrorist proxies, its nuclear advancements and its production of new weapons systems like single-use drones.

It further requires prompt notification to Congress if the intelligence community finds that Iran has made the decision to produce a nuclear weapon from its stockpiles of highly enriched uranium.

The bill also includes a new authority permitting the U.S. to quickly send weapons seized in transit from Iran to the Houthis to U.S. allies, potentially including Israel and Ukraine.

The NDAA instructs the administration to create a strategy for expanding U.S. security partnerships with Jordan and Lebanon, including working to ensure the disarmament of Hezbollah. It requires the Defense Department to set out benchmarks for cutting off support to the Lebanese Armed Forces if they fail to make progress in or are unwilling to disarm Hezbollah.

The legislation also includes a provision to withhold 25% of U.S. security assistance to Iraq until the administration certifies that the Iraqi government is taking steps to weaken Iran-aligned militia groups in Iraq and remove members of Iran-aligned groups operating as part of the Iraqi security forces, though the secretary of defense can waive those conditions.

And it requires the administration to declassify all documents related to the Iranian proxy attack on the U.S.’ Tower 22 Facility in Jordan in January 2024, which killed three U.S. service members.

Matching an executive order from the Trump administration, the legislation codifies a new designation and sanctions regime for countries engaging in wrongful detention of U.S. citizens, with a requirement that the State Department report to Congress on whether Iran should be so designated.

In addition to the Caesar Act repeal, other Syria-related provisions in the bill require the administration to report to Congress on the possibility and security concerns involved in reopening the U.S. embassy in Damascus, the U.S.’ force posture in Syria and any planned changes to U.S. forces in the country. 

It does not include a more stringent provision from the Senate version of the bill requiring the Pentagon to certify that drawing down U.S. forces in Syria would not compromise U.S. priorities.

The NDAA also provides continued authorization for the U.S. to assist vetted Syrian groups in combating terrorism in the country.

The bill additionally mandates that the Defense Department report to Congress on the possibility of expanding the Comprehensive Security Integration and Prosperity Agreement — an economic and security pact with Bahrain — to include other countries.

And it requires the administration to develop a plan to counter foreign efforts to “continue or expand” the civil war in Sudan.

The legislation does not include a House-proposed provision extending through 2029 the authorization — currently set to lapse on Jan. 1, 2027 — for the U.S. weapons stockpile in Israel, which Israel can tap into in emergencies. 

It also excludes House provisions that aimed to tackle Hezbollah’s operations in South America and to encourage defections by senior Iranian officials. A House provision awarding medals to those servicemembers involved in the U.S. strikes on Iranian nuclear facilities in June was not included either.
Other provisions from the House draft of the bill relating to antisemitism, including prohibiting Department of Defense funding for schools that failed to take action against antisemitic demonstrations, and requiring reports on antisemitism in the Pentagon and transnational antisemitic extremism, were also excluded.

A full repeal of human rights sanctions on Syria under the Caesar Civilian Protection Act is likely to pass Congress as part of the 2026 National Defense Authorization Act, after House Foreign Affairs Committee Chair Rep. Brian Mast (R-FL) signed off on the measure, according to a source familiar with the matter.

The NDAA, which Congress aims to finalize in early December after its Thanksgiving recess, will include a full repeal of the sanctions, but also a nonbinding provision urging the administration to reimpose sanctions on Syria if its new government does not meet certain human rights conditions, the source told Jewish Insider. Barring any unexpected developments, the provision should be on track to pass Congress in the must-pass legislation.

The Senate approved similar provisions in its version of the NDAA earlier this year, but the House version of the bill included no such language, and Mast’s approval was needed to incorporate the provision into the final version of the bill being negotiated between both chambers.

President Donald Trump has been urging Congress to repeal the sanctions, an effort supported by many Syrian diaspora activists, including Rabbi Yosef Hamra, the brother of the country’s last chief rabbi, who now lives in the U.S.

But others, including activists from other Syrian minority communities and some lawmakers, have argued that the sanctions should remain on the books to provide leverage and accountability to ensure the protection of minorities and the Syrian government’s cooperation on other matters like counterterrorism.

Mast had been skeptical of lifting sanctions, but indicated to JI his position was softening last week. He met earlier this month with Syrian President Ahmad al-Sharaa in Washington.

Mast told The Hill, which was first to report the news, that his position is that the sanctions should be, “Fully repealed, to have mechanisms, or rather a sentiment that sanctions should be reinstituted if a number of conditions are not met. … Still fully repealed.”

House Foreign Affairs Committee Chair Rep. Brian Mast (R-FL) told Jewish Insider that, after his meeting with Syrian President Ahmad al-Sharaa earlier this week, he’s going to “think about” his skeptical stance on the repeal of sanctions on Syria under the Caesar Civilian Protection Act. 

Mast has previously expressed concerns about lifting the sanctions, a move which the Trump administration supports.

The Senate approved the repeal of the Caesar Act as part of its draft of the 2026 National Defense Authorization Act, but the House has not yet approved similar legislation. Mast would need to approve the Senate proposal for it to be included in the final defense bill. He told The Hill last week that “discussions on Caesar Repeal are ongoing but my concerns should be obvious to anyone following the situation in Syria.”

The House Financial Services Committee voted on a bipartisan basis in July for legislation conditioning the lifting of the sanctions on Syria meeting a series of human rights, anti-corruption and counterterrorism standards.

Asked if the meeting had changed his views on the issue, Mast said that he had read at length about al-Sharaa and his background — al-Sharaa is a former terrorist commander affiliated with ISIS and Al-Qaida — prior to the meeting. Mast is a military veteran who lost his legs to a terrorist bombing in Afghanistan.

“We had a lot of conversation, good conversation,” Mast said. “I asked him very pointedly [to] explain why we’re no longer his enemy. He gave a pretty good answer. Said he was hoping for a noble future for his people, one free of radicalism, fundamentalism … and ISIS. So it was a good answer.”

Opponents of the full repeal effort argue that sanctions should remain on the books to ensure Syrian compliance with U.S. priorities and human rights, particularly in light of the massacres of religious minority groups.
