I'm wondering - is there any way to get the UK and France at war with the USSR in the 1930s, a war that 1) doesn't involve the Winter War or 2) at least has Germany as a neutral party?
I know a neutral Germany (say Hitler never comes to power and the Weimar regime somehow wheezes its way along, or whatever) leaves a big gaping hole in the lines of battle, but c'est la vie.
Anyway, it would be a strange sort of conflict, wouldn't it? Allied air strikes out of the Middle East, amphibious attacks on Vladivostok... neither side able to deploy the bulk of the army against the enemy, at least without widening the war to a Scandinavian or (God help them) Chinese front or something even more ridiculous.
