Answer:
Cold War tensions over Berlin were at their height.
Step-by-step explanation:
The speech was delivered on June 26, 1963, in Berlin, Germany, during the height of the Cold War and just two years after the construction of the Berlin Wall. The Berlin Wall had been erected by the Soviet Union to prevent East Germans from fleeing to West Germany, and it became a powerful symbol of the division between the communist and capitalist worlds during the Cold War. Kennedy's speech was a show of support for the people of West Berlin, who were living in a divided city and facing the threat of Soviet aggression. The phrase "Ich bin ein Berliner" ("I am a Berliner") became a powerful symbol of American solidarity with the people of West Berlin and their struggle for freedom and democracy in the face of Soviet oppression.
