This book, the second of two volumes, examines the presidency in last half of twentieth century America and explores the successes and failures of presidents in their foreign policy initiatives. It examines each president's ability to apply his skills to a foreign policy issue in the face of opposition that may come from a variety of sources, including the Congress, the Pentagon, the State Department, the press, and often their own in-house advisers. This volume in particular focuses on John F. Kennedy, Lyndon Johnson, Richard Nixon, Ronald Reagan, and George W. Bush.
