This is the final episode in a 5-part series marking the 80th anniversary of the end of the Second World War in August 1945.

When the Second World War began, few expected the United States would emerge six years later as an unrivaled military and economic power at the head of a new world order built upon the graves of Nazi Germany and Imperial Japan. Eighty years on, U.S. hegemony and the key global institutions for peace and free commerce are under severe pressure. In this episode, historian David M. Kennedy explores the origins of America's global age.
