In 1955, the Soviet Union formed the Warsaw Pact as a response to which action by the United States? establishing a naval blockade of Cuba escalating military action in Korea forming alliances to prevent the spread of communism refusing to participate in nuclear arms reduction talks

The correct answer is to include a rearmed West Germany in the North Atlantic Treaty Organization (NATO)

The Warsaw Pact brought the countries of the socialist bloc together in a military alliance after the Second World War.

The Second World War was won by the United States and the Soviet Union, however the two countries had opposite positions with the end of the conflict with Nazi Germany. The United States was a champion of capitalist ideology, which spread ideologically throughout the world. The Soviet Union was already adept since the Russian Revolution in 1917 of socialism. The two ideologies clashed with the end of the war, polarizing the world between capitalists and communists. The clash between the two winning powers of the Second World War occurred only on an ideological level, because both had sufficient weapons and conditions to destroy each other. The fear and the precaution of a new conflict with extreme proportions created a climate of tension in the world that prevented a direct confrontation, thus the Cold War began.
