Explanation:

The Berlin Blockade was a significant crisis during the Cold War. During the blockade, the Soviet Union blocked the Allies' access to the areas of Berlin that were under Western control. The Soviets also offered to drop the blockade if the Western Allies withdrew the Deutsche Mark from West Berlin. The Berlin blockade was significant because it highlighted the fact that there were two competing and mutually exclusive ideologies and economic visions in Europe. This convinced the United States of the need to stand firm against communist expansion.
