1. The Basic Definition

Although the term "Cold War" can technically apply to many situations, it is usually used to reference a period of hostility between the United States and the USSR that occurred after World War II and lasted until approximately 1991. It was called the Cold War because the two countries never actually reached armed conflict, unlike most wars previous.
