A frequent topic of discussion in the Alternate History group on Facebook is the Cold War and fall of the Soviet Union.
Justin Avey. "The fall of the Soviet Empire, almost without bloodshed (biggest violence was in Europe's North Korea; the Romanian Socialist Republic), if shown to somebody from a parallel universe would be called the most implausible, preposterous wishful thinking in alternate history."
"Was there really any chance that the USSR do to Warsaw (or should I say Gdansk) in 1980 what it did to Prague in 1968 or Budapest in 1956, and get away with it? If so, would it have any long-term repercussions? After all, but the 1980s Eastern Europe's economy was pretty much in the sewer and once somebody like Gorby came along the Iron Curtain would unravel."
What if the US used nuclear weapons in Vietnam? Discussion on Facebook.
What if Gen. Patton, with approval from FDR and the Brits, starts a war with the beleaguered Soviets at the end of WWII to save Eastern Europe? How does this war unfold, what happens during it, and where, when and how does it end?
