Last month, the nation's top leaders gathered to decide the U.S response to the September 11 terrorist attack. Some of the same individuals were in Washington, DC, twenty-two years ago when the United States suffered its first humiliation at the hands of Islamic militants. U.S. embassy employees were taken hostage and held captive before the world. Over the decades, incident followed incident - the bombing of the U.S. Marine barracks in Beirut, the killing of American soldiers in a Berlin nightclub, the downing of Pan Am 103, and the first attack on the World Trade Center. In "Target America," FRONTLINE uncovers a long-standing division within the nation's security apparatus about how to deal with an enemy that has been targeting America and Americans for decades.
