How would it be possible for Russia to disintegrate entirely following the end of the Cold War? Would this be possible with a POD in the early 1990s, or would the POD need to be earlier?
I guess that should the August Coup succeed, or any other coup d'etats against either Gorbachov or Jeltsyn happen, chances for Russia's desintegration would increase. This, however might have led to a situation simmilar to 1936 in China; a number of warlords (former Soviet generals and marshals) fighting for domination over Russia. And that would be unhealthy not only for a statiscit Russian, but for evety Polis, Lithuanian, Latvian and other neighbours of the former Soviet Union.
I remember newspaper articles as late as 1997 that claimed that half of Russia's autonomous republics were on the verge of seceding. Don't know how realistic that was, though. I agree the 1993 coup is the most likely cause (and a really, really underrated WI).
