Since Israel’s founding in 1948, successive U.S. Presidents and many Members of Congress have demonstrated a commitment to Israel’s security and to maintaining close U.S.-Israel cooperation. Common perceptions of shared democratic values and religious affinities have contributed to the strong bilateral ties. The question of Israel’s security regularly influences U.S. policy considerations regarding the Middle East, and Congress provides active oversight of executive branch dealings with Israel and other actors in the region. Israel is a leading recipient of U.S. foreign aid and a frequent purchaser of major U.S. weapons systems. By law, U.S. arms sales cannot adversely affect Israel’s “qualitative military edge” over other countries in its region. The two countries signed a free trade agreement in 1985, and the United States is Israel’s largest trading partner.
