Thompson examines the U.S. role--both governmental and that of Irish-Americans--in attempting to bring a resolution to the strife in Northern Ireland. He concentrates on the efforts since 1967, particularly the growth of American efforts to become the central humanitarian player in the peace process.The U.S. government stance was initially one of strict non-involvement. However, in the aftermath of Vietnam and Watergate, diminished White House authority encouraged Irish-American groups to challenge the traditional Irish policy. Movement away from strict non-involvement began with Congressional concern for the rising specter of Irish-American anger at the treatment of northern Irish Catholics. An important transition to humanitarian policy occurred during the Reagan Administration. Contributing factors that helped the U.S. government take a new direction in foreign policy were America's failure to respond to the escalation of Northern Ireland violence, a strong personal ethnic tie between the U.S. President and Speaker of the House O'Neill, a personal link between President Reagan and Prime Minister Thatcher, and intense lobbying by Irish-Americans and the Irish government. After a brief period of silent diplomacy during the Bush administration, the Clinton administration succeeded in a public blitz to endorse steps necessary to bring peace closer.
