I’m not sure in what way do you think US “financed Hitler and Mussolini” (or whatever’s going on in your head for that matter..)
But it’s a weird thing to say when the USSR/Stalin literally bankrolled the Nazi invasions of Norway and France (whatever the financing they got from the US USSR contributed a few magnitudes more).
Germany had no oil after Poland and its not far fetched that France/Britain could have just waited it out had the Soviets not bailed them out.
Greek Junta perhaps, but it was anything but stable and it collapsed because of a war in Cyprus with another NATO member..
Or are you claiming that Americans put Putin in power in Russia? Slightly far fetched but you might have a point..
Because I can’t think of anything else.
