An academic study has revealed that the United States has funneled $21.7 billion in financial and military assistance to Israel since the onset of the Gaza genocide on October 7, 2023.
The report released on Tuesday by the Costs of War Project at Brown University’s Watson Institute for International and Public Affairs details how the US State Department and the newly renamed Department of War, under both Joe Biden and Donald Trump administrations, have collectively transferred at least $21.7 billion to support Israel’s genocide in Gaza.
According to the study, the United States supplied $17.9 billion to Israel in the first year of the genocide, during former US president Joe Biden’s tenure, and $3.8 billion in the second year.
A large portion of the assistance has already been delivered, while the remainder will be distributed in the coming years, the report added.
The study notes that Washington is expected to allocate tens of billions of dollars in future funding to Israel through various bilateral deals.
Another analysis, also published by the Costs of War Project, states that the United States has spent approximately $9.65 – $12.07 billion on military operations in West Asia over the past two years.
US spending in the region, such as strikes on Yemen in March and May 2025 and attacks on Iranian nuclear sites on June 22, estimates total costs between $9.65 billion and $12 billion since October 7, 2023, including $2 billion to $2.25 billion for operations against Iran.
Although both reports rely on open-source data, they present detailed assessments of US military support for Israel and estimates of the cost of direct American involvement in the region.
Meanwhile, the State Department has not commented on the amount of military assistance given to Israel since October 2023. The White House referred inquiries to the Pentagon, which oversees only a part of the aid that is given to the Zionist entity.
The studies argue that without US backing, the regime would have been unable to maintain its genocidal campaign in Gaza for two years. The principal study was produced in collaboration with the Washington-based Quincy Institute for Responsible Statecraft.
Pro-Israel groups have accused the institute of isolationism and anti-Israel bias, allegations the organization firmly denies.
Meanwhile, Israel’s war machine continues its campaign of destruction, claiming countless civilian lives across Gaza and the wider region.
Since October 7, 2023, when Israel launched its genocidal war on the besieged Gaza Strip, more than 76,000 Palestinians, including over 20,000 children and 12,500 women, have been killed or gone missing, while in its 12-day war with Iran last June, the regime killed at least 1,604 people.
