In the two years since the October 7, 2023 Hamas attack on Israel, the U.S. government has spent $21.7 billion on military aid to Israel, according to policy analyst William D. Hartung (Senior Research Fellow, Quincy Institute). This figure does not include the tens of billions of dollars in arms sales agreements that have been committed for weapons and services that will be paid for and delivered in the years to come.
The United States has spent more than $30 billion on the war in Gaza and associated conflicts in the Middle East, with more than half of this figure devoted to military support for Israel, a new report shared with Newsweek has found. Read more.
The study, released early Tuesday, was overseen by the Costs of War project at Brown University’s Watson Institute for International and Public Affairs. Between October 2023 and September 2025, the U.S. devoted $21.7 billion in military aid to its top Middle East ally, Israel, while an additional range of $9.65−$12.07 billion has been spent by the U.S. on operations conducted in Yemen, Iran and elsewhere in the region in relation to the spillover of the conflict. Altogether, the final figure is estimated to be between $31.35 billion and $33.77 billion, excluding additional sales still slated for Israel, which has already witnessed a historic increase in U.S. military assistance at the onset of the conflict
U.S. arms have been central to the Israel Defense Forces (IDF) and Israel Police operations in Gaza, the West Bank, and beyond. The weapons in Israel’s existing inventory that are being used in Gaza and the broader Middle East come mainly from the United States. Israel’s entire inventory of combat capable aircraft comes from the U.S., including 75 F-15s, 196 F-16s, and 39 F-35s. Israel’s attack and transport helicopters are also all of U.S. origin, including 46 Apache helicopters and 25 Sea Stallion and 49 Black Hawk transport helicopters. Israel’s U.S.-supplied weapons – which include not only its combat aircraft but also tens of thousands of bombs and missiles, and advanced targeting systems – have inflicted a devastating humanitarian toll on the people of Gaza.
According to a companion report, the U.S. has spent an additional $9.65 – $12.07 billion on military operations in Yemen and the wider region sparked by or in support of Israeli military operations since October 7, 2023, for a total of $31.35 – $33.77 billion and counting in U.S. spending on two years of post-10/7 wars.
