U.S. Foreign Aid to Israel
This report provides an overview of U.S. foreign assistance to Israel. It includes a review of past aid programs, data on annual assistance, and analysis of current issues. For general information on Israel, see Israel: Background and U.S. Relations in Brief, by Jim Zanotti.
Israel is the largest cumulative recipient of U.S. foreign assistance since World War II. Successive Administrations, working with Congress, have provided Israel with significant assistance in light of robust domestic U.S. support for Israel and its security; shared strategic goals in the Middle East; a mutual commitment to democratic values; and historical ties dating from U.S. support for the creation of Israel in 1948. To date, the United States has provided Israel $146 billion (current, or noninflation-adjusted, dollars) in bilateral assistance and missile defense funding. At present, almost all U.S. bilateral aid to Israel is in the form of military assistance, although from 1971 to 2007, Israel also received significant economic assistance.
In 2016, the U.S. and Israeli governments signed their third 10 year Memorandum of Understanding (MOU) on military aid, covering FY2019 to FY2028. Under the terms of the MOU, the United States pledged to provide—subject to congressional appropriation—$38 billion in military aid ($33 billion in Foreign Military Financing grants plus $5 billion in missile defense appropriations) to Israel. This MOU followed a previous $30 billion 10-year agreement, which ran through FY2018.
Israel is the first international operator of the F-35 Joint Strike Fighter, the Department of Defense’s fifth-generation stealth aircraft, considered to be the most technologically advanced fighter jet ever made. To date, Israel has purchased 50 F-35s in three separate contracts, funded with U.S. assistance.
Basically a lot of the money we are spending in Israel is coming back to support our military production. Depending on how you feel about that it’s either pork barrel spending or a win win. We support our allies, Keep the conflict overseas, and help support our military contractors at home.
