America decides to invest in developing it’s air and tank forces in the early 30’s, instead of once again cutting it’s military budget for everything except the Navy. By the time Germany starts to get aggressive in Europe, the US has developed a tank based on Christie’s designs (instead of making him to to Russia and sell it to them) and a series of updated fighter air frames. When WWII starts to brew up, America is more than happy to sell these updated designs (plus some of the tactical doctrine developed during our experimentation) to the Brits and Russians (we WOULD have sold them to the French as well, but being French they turn up their collective noses, since it Wasn’t Made In France).
I think that this small change alone would have put the US in a much better position to respond to the needs of our allies initially, and once we entered the war would have given us a credible force right from the get go, instead of having to learn the hard way.
Or, the US does not take an isolationist stance during the 30’s, and instead the politicians are able to convey to the people that we need to be more proactive (plus, that the meme about off-shoring and trade is a bunch of bullshit, and that ultimately it hurts the country to try and keep jobs and manufacturing here at the expense of international trade…something that seemingly we still haven’t learned).
On the Germans side, Hitler comes to power just as he does, but he suffers a partial stroke that causes him to shut the fuck up and let his generals plan and actually execute their strategy and tactics in Russia without him joggling their arm or changing their plans. I believe that Hitlers interference was the single greatest weapon against Germany that existed, and without it I think there was a very good chance that the Germans would have plowed under the Soviets in the initial assault. It was Hitler, changing the plan and further dispersing German resources, plus dragging his feet on the logistics and resupply problems (winter was coming, moron) that ultimately lost Germany the war.
Or, maybe that Hitler dies in prison and the Nazi party is discredited completely, and the republic survives and eventually becomes stronger. I’m not sure if this would have avoided war, but I think it would have changed what the war was (maybe limited to a war with France and possibly the UK).
Of course, the ultimate ‘what if’ is, if Germany had not invaded Russia at all, but allowed the secret treaty/pact to remain, and concentrated on wiping out the Brits once and for all. I think that war with Russia was inevitable, but if Germany had consolidated it’s power in western Europe, had integrated them into a new uber-German empire, and crushed or at least forced the Brits to comply, they would have had a massive amount of resources at their disposal…possibly much of the former British empire, certainly most if not all of the Brit possessions in the ME and North Africa.
