Final answer:
The responsibility for the Cold War cannot be solely attributed to one country, as both the United States and the Soviet Union played significant roles in its development. The United States was primarily responsible due to its policies of containment and efforts to spread democracy. However, the Soviet Union's aggressive expansionist policies also contributed to the tensions.
Step-by-step explanation:
The responsibility for the Cold War is a complex and debated topic. It cannot be attributed solely to one country, as both the United States and the Soviet Union played significant roles in its development.
The United States can be seen as primarily responsible for the Cold War due to its policies of containment and efforts to spread democracy, which were deemed threatening by the Soviet Union. The Truman Doctrine, the Marshall Plan, and the establishment of NATO all contributed to the tensions between the two superpowers.
However, the Soviet Union is also responsible for the Cold War. The aggressive expansionist policies pursued by Joseph Stalin, such as the establishment of communist governments in Eastern Europe, the Berlin Blockade, and the Soviet's pursuit of nuclear weapons, were key factors that escalated the tensions.
