Answer:
The Soviet Union and its allies created the Warsaw Pact.
Step-by-step explanation:
The Warsaw Treaty was a military alliance between the socialist countries of Eastern Europe, under the leadership of the Union of Soviet Socialist Republics (USSR), signed on May 14, 1955 in the Polish capital, Warsaw.
The Warsaw Pact was a direct reaction to the rearmament and inclusion of West Germany in the North Atlantic Treaty Organization (NATO) in 1954, also serving as a pretext for the creation of a military force that could challenge NATO while allowing the USSR expand and preserve its area of influence.
The Warsaw Pact lasted until 1991, when it lost its functionality in the face of the collapse of the USSR and the end of the Cold War.
