It remembers me of a fictional documentary like 20 ago in German TV covering the third world war. The premise was a military coup in Russia. Back then, Jelzin just squashed the coup attempt against Gorbatshev. The development was very cold war like, focused on Germany and ended with a full scale nuclear war. Quite chilling. Only criticism I would have is that the Russians were the bad guys, so.

Edit 1: I think that's the one (in German): https://www.youtube.com/watch?v=fJ3vkqDaPdg

Edit 2: It is set before the fall of the USSR and the German reunification, classic cold war stuff. Just watching it. Forgot the details, but damn the fall of the iron curtan could really have ended differently. Basically, Gorbatshev was forced to step down and military hawks took over.
