As West Germany and West Berlin become more affluent, East Germans begin to flee their country for their more prosperous neighbor. Khrushchev demands that the British, French, and Americans leave West Berlin, but they decline and the opportunity for a peaceful resolution is dashed when the Soviets walk out on the Paris Summit of 1960 because of the U-2 incident.
On the night of August 12, 1962, East German security forces begin to build the Berlin Wall. In response, a tense standoff between U.S. and Soviet forces ensues. In 1963, President Kennedy delivers his famous "I am a Berliner" speech. Interviews in Episode 9 include Anatoly Gribkov, Valentin Falin, Stefan Heym, Egon Bahr, Raymond L. Garthoff and Conrad Schumann. https://edition.cnn.com/2014/01/02/world/the-cold-war-landmark-documentary/index.html
