Historical knowledge in its various forms - learned, observed and experienced - is one of the principal intellectual resources available to politicians and the officials who serve them. These policy communities habitually, though sometimes naively, inexpertly and misleadingly, use history in the crafting of policy. In this book the question of whether politicians use history wisely and judiciously is posed about those who inhabit the Kremlin as well as the White House. The question has several dimensions which are examined here in a series of original essays. Is historically based reasoning rational? How influential is historical knowledge in deliberations over policy? And does historically based reasoning lead to sound decisions about future policy? The authors range over a wide area of economic and political issues - Palestine, Soviet policy, British and United States hegemonies and comparable predicaments, United States acceptance of its international responsibilities, Soviet expansionism, the Cuban Missile Crisis, US policy towards Latin America and the historical content of President Bush Sr.'s response to Iraq's invasion of Kuwait.
