Our historical documentary series on the history of the Cold War continues with a Q&A video answering these questions: When did the Cold War start? When did the Cold War end? We have stated that the first hydrogen bomb was detonated by the Soviet Union but the US detonated Ivy Mike first? What is the difference? When we talked about Operation Unthinkable, lots of people pointed out the atomic advantage that the US enjoyed. Why didn’t we mention it? We get lots of requests for us to do an episode on the subject “X”. Why haven’t you done that yet? Fundamentally, what IS the Cold War? What does it refer to? Could a non-nuclear war have been fought between the superpowers?
