The Cold War was a time of geopolitical hostility between the United States and the Soviet Union. This conflict spanned about 45 years until the Soviet Union dissolved in the early 90s. However, no physical fighting ever occurred, there was only a consistent state of friction between these two nations.
No, the cold war should not be considered a warShow moreShow less
Although the Cold War was an ideological competition between the Soviet Union and the United States, that does not justify defining this period of conflict between the two nations as an actual war. While this Cold War may have led to other proxy wars and even the eventual collapse of the Soviet Union, no true armed conflict ever occurred. Furthermore, because this Cold War was mostly about two superpowers trying to exert superiority over the other in everything from sporting events to space programs, this period of conflict cannot be accurately defined as a war, just a competition.
There was no formal declaration of war during the Cold War
Neither the Soviet Union nor the United States ever declared war on the other nation during this period of ideological conflict with one another. Without an outright declaration of war, there could not ever have been a legitimate war of any sort that took place between the Soviet Union and United States.
