This book is about U.S. policy makers who have wielded enormous influence, largely behind the scenes, since the end of World War II. The advent of the Cold War brought new problems of national security for the United States. As a result, U.S. presidents no longer sat down with their secretaries of state to determine the nation's foreign policy. Instead, postwar chief executives reached out to individuals in the intelligence and military organizations and, increasingly, to advisers in the White House. The Policy Makers examines seven such advisers from public servants in the state department to CIA directors and U.S. senators and the policies each adviser influenced. By focusing on individuals whose policy making role was often unknown to the public, Anna Kasten Nelson and her contributors shed light on the myriad ways in which the postwar foreign policy of the United States has been shaped, sometimes in ways very damaging to the nation's security.
