If you do a “cui bono?” type of retrospective analysis, I can’t think of any other way to see it other than that “the left” won.
Do you think that the American and British boys dying in Europe in 1944 (my great uncle included) were doing it so their great granddaughters could be raped by Pakistanis or so their great grandsons could perform sodomy in public?
Do you think either of those things would have happened if the war went the other way? Of course it is impossible to know what other, unanticipated negative consequences would come with it and which outcome was ultimately better for humanity....but it is pretty easy to say that this outcome is the most “left” of the two options.
What the generation of the 40s did and those do today are separate things, separate people.
As to “do you think either of those things would have happened if the war went the other way?” - yes, yes they would. Mustache man was cosy with the mohammedans
