1. The issue between the U.S. and the Soviet Union was known as the Cold War because it never escalated into direct military conflict between the two superpowers. It was characterized by political and economic competition, espionage, propaganda, and proxy wars fought through allies or third parties. Despite tensions and occasional close calls, neither side was willing to risk a nuclear war that could lead to mutual destruction or global catastrophe. The term "cold" refers to the absence of direct military action rather than the absence of hostility or aggression.
2. The Cold War lasted from the end of World War II in 1945 until the collapse of the Soviet Union in 1991, which marks the end of the bipolar world order and the beginning of a new era of multipolarity and globalization. The duration of the Cold War varied depending on the definition and scope used, but it generally refers to the period of intense rivalry and ideological confrontation between the U.S. and Soviet Union that shaped international relations and domestic politics in many countries.
