Gregory's Server@yogthos I can’t comment on who started what or why the Cold War persisted the way it did, that’s debatable. I can say that USSR did develop a world ending arsenal and this was perceived by US as a threat. So one nation under duress is questionable. With two nuclear powers in frequent confrontation the entire world was under duress.
@rodroidrx it's not debatable who started the Cold War. The fact that it was the west is a well documented fact. US was also the first country to develop nuclear weapons and use them on civilian population of Japan to send a message to the Soviet Union.
Meanwhile, USSR always tried to come to treaties to disarm and deescalate, the west was never interested.
Highly recommend watching this documentary https://www.imdb.com/title/tt1494191/
