The American Israel Public Affairs Committee (AIPAC) was founded in the 1950s. It is an American lobby group located in Washington, DC seeking to promote the passing of American legislation and government budgetary allocations that they deem favorable to Israel. AIPAC often, though not always, tends to support Israeli government policies. AIPAC is today one of the most influential foreign lobby groups in the United States.
