In this arresting volume Kenneth Thompson has combined academic research with acute observation in approximately equal proportions. Research has been focused on the theories and practices of those who, whether in thought or action, have played an influential part in the development of American foreign policy during the past decades. Originally published in 1960. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
