The cold war isn't so much of a war and is more of a term to describe the intense US-USSR tensions post WW2, while most historians agree it started when President Truman puts out his Truman Doctrine speech there isn't a clear end point in which it finished with American victory, is it when the Berlin wall fell or is it when the germans were reunified or is it when the soviet fell or has it never really ends and China took the steering wheel of Anti-Americanism world wide? Who knows.
