The USSR would span its territories in the 80s but be led by a competent Marxist leninist party. Same for the Warsaw pact countries and Yugoslavia. These were caused by revolutions popping up all across the globe and other areas.
The US choice would have itself devolve into chaos while its power and influence decreases. Infighting would break the US into pieces but territories like hawaii and alaska would gain independence. The main government would be torn asunder and the CIA rogue and unfunded.
I think the revival of the USSR would be the smartest choice. Having a pact of the USSR + current day China would be massive. From there on we can work towards the inevitable fall of the US, but with a strong socialist world power to pick up the pieces.
A fall of the US alone could backfire into a new fascist state or multiple fascist rogue states even, which would not be ideal.
Plus, reviving the USSR improves the lives of millions of people directly, so that’s great.
Excellently put. The world needs guiding examples, evening the playing field by taking out the US isn’t enough, why fight the fascists on even grounds?
