I meant the next general war after everyone dogpiles the USSR like it's Revolutionary France as I described in my previous post -- which ATP was responding to -- so I don't think the Politburo is doing anything at that point except desperately rebranding themselves as apolitical civil servants more than happy to work for whoever the Coalition installed. Kirill Vladimirovich Romanov might be in exile in France if his marriage is a Julian date and the displacement is a Gregorian date, but otherwise I can find no survivors and probably some other royal line will need to be transplanted. I don't see the victorious great powers trusting the Russian people to not vote Communism back in if allowed to form a republic. Especially if the French Third Republic tries to ally with the USSR.
Would the socialists be running France? I don't think socialists will be allowed to run anywhere after the USSR demonstrates where that leads.
I don't think early 20th century Italy and France are very good at assessing risks. If they were the French would have pressured the Russians to let Serbia slide and the Italians would have stayed neutral and used belligerent money to build up their military industry like America and to a lesser extent Spain. Maybe they learn something from the intervention in Russia, but I said if I had to put money, not that I was confident. There are a half dozen more or less great powers in Europe after Russia is neutralized and I don't think any of them is even close to a coin flip for being the one to start the next big war. To say nothing of the possibility that a smaller or non-European nation does something foolish that kicks things off.
