Quizplus · Accepted Answer

The Soviet Union and the United States were the two major superpowers during the Cold War, and both had veto power in the United Nations Security Council. This meant that either of them could veto any decision or motion, making it difficult for the UN to take collective action on security issues. As a result, many important security issues were left unresolved, leading to a lack of collective security during the Cold War.
