Ah so the rump USSR can still reach the 100th anniversary in 2022? But without the military parades. Heck, I think with the civil war ongoing, the people of the USSR would even forget that their country managed to make it 100. I could see it being absorbed by the Tsarist Republic afterwards.I too can't see Soviet Union lasting long time. It would face its end during2020's or at least by 2030 latest. And frankly, it probably would be best for Soviet people unless something worse emerge.
And there is yet one thing: Cabal China is going to do something. Or it has to launch its bioweapons in 2020's or at least by 2030 ready or not. Its population is very close that point that government just can't feed them.
Looking at this map for AANW made by Quantum Branching from DeviantArt, the A4 and the UN might need to put some military presence there because Cabal China might have their eyes on it for their "expansion".
Thankfully Mongolia has allowed the A4 to station large military forces to keep Cabal China in check.
