Final answer:
International Communism was indeed based on the belief that all communist movements and revolutions around the world were led, promoted, and financed by the Soviet Union.
Step-by-step explanation:
The concept of "International Communism" was based on the belief that all communist movements and revolutions around the world were led, promoted, and financed by the Soviet Union. This idea is true (T). During the Cold War, the Soviet Union, under leaders like Joseph Stalin and later Nikita Khrushchev, supported and influenced communist movements and countries globally. The Soviet Union's engagement in promoting communism can be seen in their alliances with countries like China, their economic aid through organizations like COMECON, and their efforts to spread communist ideology.
