I heard how in the 70's, the Soviet Union had trouble with its economy but was saved right during the oil crisis of 1973 where it got the opportunity to export oil and survive for at least 16 more years. Let's say the oil crisis doesn't happen and the Soviet Union goes into deeper trouble and becomes unstable to the point of it collapsing in 1981 or maybe a tiny bit earlier, not too sure. How would Brezhnev handle this crisis and what methods would've he used to prevent the destabilization in this alternate history? How would the process go? What would've happen to Eastern Europe, Russia and the former Soviet republics and how would they be to this modern day? How would the US policy and Ronald Reagan's fate be changed if the USSR collapses earlier? What would our world be like now? Would a strong figure like Putin rose to power and there'd be tensions with the west like it is in our timeline?
