John Dumbrell 
American Foreign Policy [PDF ebook] 
Carter to Clinton

This book examines the history of US foreign policy since the Vietnam War. It focuses on four themes: the legacy of Vietnam; the ending and aftermath of the Cold War; the debate over American international decline; and the frequently undemocratic conduct of US foreign policy. The book considers alternative explanations for the Cold War’s end. It evaluates the foreign policy leadership of Presidents Carter, Reagan, Bush and Clinton and assesses prospects for US foreign policy after the Cold War.
