Decode the Cold War: Your Go-to Glossary for Critical Terminology


American and Soviet flags side-by-side main

World War II led to worldwide death and destruction, including two examples of the horrible possibilities of nuclear weapons. Two superpowers, the United States and the Soviet Union, remained. They had competing cultures and ideologies but feared the deadly effects of direct conflict. The result was a Cold War, which still had a lot of troubles, but not a nuclear winter. It ended with the fall of the Soviet Union in 1991.

There are many basic terms we use when studying the Cold War. Let’s delve right in.
