President Harry Truman recognized Israel on May 15, 1948, within minutes after Israel declared its independence. Past American presidents, encouraged by active support from civic groups, labor unions, political parties, and members of the American and world Jewish communities, supported the concept, articulated in Britain's 1917 Balfour Declaration, of a Jewish homeland
After World War II, United States support for a Jewish state grew with the desire to help settle the large number of Jewish refugees, displaced persons, and survivors of the Nazi holocaust. Popular support for Israel among U. S. Jews and significant segments of the Christian community has been supplemented by a general identification with Israel as an advanced democratic society with strong liberal and humanitarian values, as a "pioneering" and innovative nation, and as a beleaguered refuge surrounded by hostile and belligerent Arab neighbors.
