What was the primary goal of the Warsaw Pact?

The primary goal of the Warsaw Pact was to establish a military alliance to counter NATO. Formed in 1955, the Warsaw Pact was a collective defense treaty among the Soviet Union and seven other Eastern Bloc socialist republics in response to the integration of West Germany into NATO. The pact was aimed at ensuring mutual defense and military collaboration among member states, reinforcing the Soviet Union's control over its satellite states in Eastern Europe, and counterbalancing the perceived threat posed by the Western military alliance. This context underscores the significance of the Warsaw Pact during the Cold War as both a political and military strategy for the Eastern bloc.

The other options do not accurately reflect the intent of the Warsaw Pact. The alliance was distinctly not among capitalist countries, nor was it a trade agreement or a collective security agreement within the framework of the United Nations. These aspects clarify why the chosen answer correctly captures the essence of the Warsaw Pact's primary objective.
