You didn't provide the answers, however, European Communist countries didn't have much choice since they were liberated by Communists during the war. The Asian countries did have a choice and chose to adopt it which is why there were many wars, both civil and one country fighting another like in Vietnam or Korea. They were supported by the Soviets and China.
