2: Iron Curtain: 1945-1947 | Cold War

The wartime allies demobilise - the United States enjoys its economic strength and resurgence while Britain and the rest of Europe is exhausted. A new series of purges takes place in the Soviet Union, and is ravaged by famine. Germans are expelled from territories now given to Poland by the Soviet Union, and differences emerge over Germany's post-war rehabilitation. Stalin increases his grasp on Eastern Europe, although does not intervene on the side of the Communists in the Greek Civil War. Britain's power influence goes into decline, weakened from the war and a severe winter. Food shortages threaten stability throughout Europe. The United States begins to adopt a more assertive foreign policy, countering Soviet influence in Turkey and Iran. Interviewees include Lord Annan, Sir Frank Roberts and Paul Nitze. The pre-credits scene features Winston Churchill's 1946 ''Iron Curtain'' speech in Fulton in the United States, which set the tone for confrontation.
