I pretty much can see the Soviets are screwed, either through outright war against Germany (Weimar) or economic collapse later on.
Both Weimar World and Zionist Uganda have Civil Wars as the end of the USSR, and with the added strain of Yakutia as a threat, the worse Afghan War and the lack of Yakutia as a part of the USSR, thing might be even worse for them. The Weimar World Civil War will be closer, I think, as the direct effects on the USSR from that TL will be bigger, and that Civil War is also earlier.
They can't lose the Pacific Federation (Weimar), or Vladivostok (Zionist Uganda), as those are already gone, though.
But yes, the USSR is screwed.
Altough Israel would be less influential (on it's own, it would be a Commonwealth state, probably) without WW2 (Congo, for one thing, and Somalia), and the immigration that preceeded it.
