Which of the following were Soviet Cold War actions?

The correct answer identifies specific actions taken by the Soviet Union during the Cold War, which reflects their strategic aims and ideological commitment to spread communism. The annexation of Eastern Poland and the Baltic countries was a direct result of the Soviet Union's territorial ambitions following World War II. They sought to extend their influence by integrating these nations into the Soviet sphere, thus solidifying their control over Eastern Europe.

The response regarding the installation of an Eastern Europe capitalist system is inaccurate as the Soviet Union promoted a communist ideology throughout that region, rather than capitalism. Similarly, while the creation of Communist puppet governments in both North Korea and East Germany is indeed a fact of the Cold War, it was not addressed in the selected answer. Therefore, selecting only the first option overlooks the broader context of the Soviet Union's actions and ignores the significant impact of having established communist regimes in these areas.

In contrast, recognizing all of the listed actions helps illustrate the extensive scope of Soviet activities during the Cold War, emphasizing their strategic maneuvers to strengthen communism beyond just territorial annexation. Understanding these elements is crucial for grasping the dynamics of the Cold War and the fundamental principles of Soviet foreign policy during that era.
