How did the Berlin Airlift demonstrate credible commitment in the Cold War?

Correct answer: Western powers supplied West Berlin without direct war

Direct answer: A. In 1948, the Soviet Union blocked land and water routes to West Berlin, which lay inside the Soviet occupation zone. The United States, Britain, and their partners responded with the Berlin Airlift, carrying food, fuel, and other necessities by aircraft for many months. They did not abandon the city, but they also avoided opening a direct ground war. This showed credible commitment: their actions proved that they would defend West Berlin and support their allies despite danger. Option A is correct. Option B is wrong because the Western powers continued supplying the city. Option C is wrong because the Soviet blockade did not immediately win; it was lifted in 1949. Option D is wrong because the United Nations did not end Germany. Memory cue: blockade below, airlift above, resolve without direct war.
