Final answer:
Option 'a. Hitler broke the non-aggression pact with the Soviet Union' does not accurately explain how WWII led to the Cold War, as it was the post-WWII tensions and actions including ideological disputes and quests for influence that set the stage for the Cold War.
Step-by-step explanation:
The statement that does NOT accurately explain how WWII led to the Cold War is 'a. Hitler broke the non-aggression pact with the Soviet Union.' The breakage of the non-aggression pact resulted in the Soviet Union joining the Allies against Germany, but it did not directly lead to the Cold War.
The post-WWII actions and tensions set the stage for the Cold War. These included the Soviet Union’s expansion into Eastern Europe and breaking free election promises (option b), as well as the lack of disclosure by the United States about the atomic bombs (option c), and the division of Germany alongside the Soviet's treatment of their zone (option d).
The Cold War was primarily a result of ideological differences and the quest for influence between the United States and the Soviet Union. Both superpowers sought to extend their ideologies and power, leading to various conflicts around the globe without direct military engagement between the two. This period was marked by intense rivalry, espionage, political clashes, and an arms race including nuclear stockpiles.
