7 Oct 2025 – The United States has provided at least $21.7 billion in military aid to Israel since the start of the Gaza genocide on 7 Oct 2023. However, under both the Biden and Trump administrations, additional tens of billions of dollars in arms sales agreements have been committed for weapons and services that will be paid for in the years to come. This report covers the spending streams that have gone into that $21.7 billion, as well as detailing the billions in commitments that the U.S. government has promised for arms to be supplied in the future, much or all of which will be paid for by additional appropriations for military aid to Israel.
Given the scale of current and future spending, it is clear the Israeli Defense Forces (IDF) could not have done the damage they have done in Gaza or escalated their military activities throughout the region without U.S. financing, weapons, and political support.
According to a companion report by Linda J. Bilmes, 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 7 Oct 2023, for a total of $31.35 – $33.77 billion and counting in U.S. spending on two years of war.
Conclusion
Without U.S. money, weapons and political support, the Israeli military could not have committed such rapid, widespread destruction of human lives and infrastructure in Gaza, or escalated its warfare so easily to the regional level by bombing Syria, Lebanon, Qatar and Iran.
Without U.S. support, the Israeli government would have no combat aircraft to drop bombs and many fewer bombs. An increasing share of Israel’s arsenal would be down for maintenance without U.S. government or U.S. contractor mechanics and spare parts. In addition, Israel’s government could not have built a military of its current size and sophistication without U.S. financial backing.
Thus far, the U.S. government has not acted to stop the killing by cutting off military aid, weapons sales and deliveries, or assistance with maintenance and spare parts.
