In 1951, Congress voted to help Israel cope with the economic burdens imposed by the influx of Jewish refugees from the displaced persons camps in Europe and from the ghettos of the Arab countries. Arabs then complained the U.S. was neglecting them, though they had no interest in or use for American aid then. In 1951, Syria rejected offers of U.S. aid. Oil-rich Iraq and Saudi Arabia did not need U.S. economic assistance, and Jordan was, until the late 1950s, the ward of Great Britain. After 1957, when the United States assumed responsibility for supporting Jordan and resumed economic aid to Egypt, assistance to the Arab states soared. Also, the United States was by far the biggest contributor of aid to the Palestinians through UNRWA, a status that continues to the present.
U.S. economic grants to Israel ended in 1959. U.S. aid to Israel from then until 1985 consisted largely of loans, which Israel repaid, and surplus commodities, which Israel bought. Israel began buying arms from the United States in 1962, but did not receive any grant military assistance until after the 1973 Yom Kippur War. As a result, Israel had to go deeply into debt to finance its economic development and arms procurement. The decision to convert military aid to grants that year was based on the prevailing view in Congress that without a strong Israel, war in the Middle East was more likely, and that the U.S. would face higher direct expenditures in such an eventuality.
Israel has received more direct aid from the United States since World War II than any other country, but the amounts for the first half of this period were relatively small. Between 1949 and 1973, the U.S. provided Israel with an average of about $122 million a year, a total of $3.1 billion (and actually more than $1 billion of that was loans for military equipment in 1971-73) . Prior to 1971, Israel received a total of only $277 million in military aid, all in the form of loans as credit sales. The bulk of the economic aid was also lent to Israel. By comparison, the Arab states received nearly three times as much aid before 1971, $4.4 billion, or $170 million per year. Moreover, unlike Israel, which receives nearly all its aid from the United States, Arab nations have gotten assistance from Asia, Eastern Europe, the Soviet Union and the European Community. Congress first designated a specific amount of aid for Israel (an "earmark") in 1971.
