A provision in the 2027 draft US defence bill could bind the two countries’ weapons industries closer than ever.

A provision in a bill before the United States Congress could tie the US and Israeli militaries far more closely together, deepening their cooperation on weapons research, production and technology.

The proposal, titled the United States-Israel Defense Technology Cooperation Initiative, appears as Section 224 of the House Armed Services Committee’s version of the fiscal year 2027 National Defense Authorization Act (NDAA), the annual US defence policy bill.

The measure is still at an early stage. The NDAA is passed by Congress each year to set US military policy and authorise defence programmes and spending levels.

If enacted, the provision could mark a significant change in one of the world’s closest military relationships, shifting the two countries from a partnership centred largely on US military aid towards one in which their defence industries are more deeply intertwined.

Section 224 would require the US defence secretary to appoint an “executive agent”: a single official to coordinate military cooperation between the US and Israel.

That work would cover joint research and development, the shared production of weapons, and the linking of military systems and data.

“What Congress is trying to do now is find different ways of entrenching the relationship so deep in America’s own defence industrial base that it’s impossible to root it out,” Josh Paul, a former US Department of State official and founder of the advocacy group A New Policy, said about the controversial provision.

“A new section of law in the National Defense Authorization Act would give Israel unprecedented access to American technology and would force the United States military to integrate Israeli defence technologies into our own critical military supply chain, giving Israel incredible leverage over America’s own defence priorities,” he added in a video posted on social media on Friday.

The two countries have already built missile defence systems together, such as the Iron Dome.

The bill would extend their joint work into many more areas of modern warfare, from artificial intelligence (AI) to drones and cyber-operations.

The provision comes amid turmoil in the Middle East following joint US-Israeli attacks on Iran earlier this year. In February, US and Israeli forces attacked Iran, triggering five weeks of war; Iran struck back at Israel and at US bases in the Gulf region before a ceasefire took hold in April.

Israel is also facing genocide allegations in a case brought by South Africa at the International Court of Justice, the top court of the United Nations, over its war on Gaza.

Decades of support

The bill must first clear the House Armed Services Committee, which is due to take it up in early June, and then pass the full House and the Senate.

It was proposed by the committee’s Republican chairman, Mike Rogers, and its most senior Democrat, Adam Smith, giving it support from both main parties, even as opinion polls suggest growing opposition among most Democrats and some Republicans to further military support for Israel.

The US has supported Israel’s military for decades.

Since 2008, US law has required Washington to protect Israel’s “qualitative military edge”, keeping its forces stronger and more advanced than those of any rival in the region, on the grounds that a small country must rely on better weapons rather than greater numbers.

Under the current aid deal signed during the administration of former President Barack Obama, Washington provides Israel with about $3.8bn a year in military assistance. The 10-year agreement runs through 2028.

Israel is the largest recipient of US foreign aid since 1948, almost all of it now military and worth more than $300bn when adjusted for inflation. 

The nature of that support may now be changing. Prime Minister Benjamin Netanyahu said recently that he wants to end Israel’s reliance on US military aid within 10 years, saying his country had “come of age”.

Closer cooperation between the two defence industries, rather than cash, would likely fit that goal.
