A direct outcome of the Berlin Crisis ending in 1949 was?

• A. Stalin called off the blockade
• B. Lead to the creation of NATO
• C. The Berlin Wall was immediately built
• D. East and West Germany reunited under US control

Answer: (B)

When Western powers faced Soviet pressure over Berlin, they demonstrated they would defend their position in Europe by coordinating a collective security approach. The sustained airlift to supply West Berlin showed the Allies could stand together and deter further Soviet moves. That resolve and shared defense outlook directly led to establishing a formal military alliance among Western nations—the North Atlantic Treaty Organization—in 1949. This alliance created a concrete framework for mutual defense and symbolized the new East–West divide of the early Cold War.

Why the other ideas don’t fit as the direct outcome: the Berlin Wall wasn’t built until 1961, long after 1949; East and West Germany wouldn’t reunify under US control—their eventual reunification happened in 1990 and involved both German states, not a unilateral US arrangement; and while the blockade’s end happened around that time, the clearest immediate outcome tied to ending the crisis was NATO, the formal security pact that shaped Western defense for decades.
