Sorry are you referring to WWII in a discussion about the cold war, which really wouldn’t ramp up for at least 5 years afterwards and would be mostly characterized by the 60s-80s and saying “if you look at the history”??
Maybe you should take a gander at some history books buddy, it’s not like 10 years between medieval wars where technology would barely have inched forward, instead being an age of innovation where we went from planes to space travel in <50 years with the Soviet engineering beating the US at 2 out of 3 steps of the space race lmao.
Not to say the soviet Union was some glorious infallible place or anuthing, I just think your comment is absurd and kinda irrelevant.
