This study presents the thesis that religious cleavages in Lebanon have been the major factor behind most of the country's problems since the achievement of independence in 1943. The coming of the Palestinians in 1948 and in the 1970s upset Lebanon's delicate sociopolitical balance between Christians and Muslims in favor of the latter. The study's four chapters describe the origins of Lebanon's religious groups, the arrival of the Palestinians, Lebanon's emergence as the sole Palestinian guerrilla base, and the outbreak and aftermath of the Lebanese civil war of 1975-1976. Finally, suggestions are made for the resolution of the continuing Christian-Muslim conflict, notably the alternatives of federalism and confederalism as possible future political arrangements for Lebanon.

Hamas, or the Islamic Resistance Movement, is a Palestinian Islamist military and sociopolitical movement that grew out of the Muslim Brotherhood, a Sunni religious and political organization founded in Egypt in 1928 that has branches throughout the world. The United States, Israel, the European Union, and Canada consider Hamas a terrorist organization. The overarching U.S. goal regarding Hamas is to deter, transform, marginalize, or neutralize it so that it no longer presents a threat to Israel's security, to a peaceful and lasting resolution of the Israeli-Palestinian conflict, or to other U.S. interests. This report discusses U.S. efforts and policy debates on these issues.
