The United States is Israel’s closest ally, and its support is a central pillar of Israel’s national security. The US provides Israel access to purchase advanced weapon systems, ammunition and weapon emergency supplies in times of war, intelligence sharing, opportunities for cooperation in defense technology, and crucial diplomatic cover at the UN Security Council and elsewhere. It also provides Israel with regular security aid, to be spent in the United States, currently at an annual rate of $3.8bn (under an MOU that expires in 2028). Since October 2023, the US also offered active military support, in a break from the historical norm. It contributed substantially to Israel’s defense against Iranian ballistic missiles, in conjunction with Arab regional partners, and bombed nuclear sites in Iran in support of Israel’s campaign in the “12 Day War” of June 2025.
These technological, intelligence, and security cooperations have benefited the US, especially in recent years, and Israel has supported broader American aims in the region. Equally important a motivation for US support for Israel, however, is widespread sympathy for the country among the American population and its political elite.
