Are you also assuming that Germany never invaded Russia, because if they were at war with each other and Nazi Germany attacked the U.S. then the U.S. probably would have won.

Before Göring switched from bombing airstrips and military production facilities to The Blitz, the British were rapidly losing their ability to defend themselves. If their air power was destroyed, it was simply a matter of time before their Navy was dealt with and a land invasion began.

As Ironic said, the Nazis would have needed a serious technological edge to deal with a country as large as America. I could see a joint invasion with Japan in the mid to late 40's as a possibility, had the Depression continued and Japan being much more aggressive in neutralizing US naval power in the Pacific

It would be a massive task for an inter-continental invasion for a hypothetical Nazi invasion of North America or of an American invasion of Nazi Europe; D-day would of never happened had the British Isles fallen to axis powers, the UK landmass acted as a giant aircraft carrier and harbour for the western allies. The logistics and man power required for any invasion is huge and a water born invasion is never easy and one across an ocean unlikely.

If you spin the world around and have a look at the battles of the pacific and what was required to invade a small island, too just get a foot hold for any kind of platform, you can see the task in hand is near impossible. First you have to get naval superiority then you must gain air superiorty, then you must also get within range to strike by doing both the above again and again and again, and finally you must invade a defending force who are expecting you.

The US had a very very low civilian casualty rate in the war and this is due to its advantage of its location in relation to the conflicts, this advantage is any invaders disadvantage.

Looking at what actually happened during the war and the difficulties that the US had in fighting wars away from their territories and remembering also that their enemy also had other enemies, namely Russia and China but also the UK and her colonies(India etc) plus the numerous other allied forces. Had the allies fallen and 2 powers remain any intercontinental invasion would not of happened even hypotheticly(?). Most likely the war would of either spread into a land grab of Africa, unless the US could react fast they would be on the backfoot. What would of most likely happened is exactly what happened between the US and the Soviet Union, a 'Cold war' would of ensued with everyone on tenterhooks until either one side collapsed(as happened) or until one side pressed the big red button.

Nazi Germany would have to defeat USSR to win the war (assuming US didn't participate). They were having a hard time attempting that. But assuming they did win, and joined forces with the Soviets and Japanese...it makes a very strong coalition to invade US (geographically strategic for attacks plus joint technologies). But Germany alone wouldn't win - maybe capture key cities in the East Coast but that's all.

That's almost impossible to imagine.

Regardless of what nations were involved Russia was getting invaded by Germany sooner or later. One of the main themes of Mein Kampf was the invasion of Russia, the eradication of the Slavs, and the usurpation of Russian land and resources.

In one sense WWII in Europe was defined by, or predicated on, the eventual invasion of Russia by Nazi Germany.

That wouldn't have happened.

Germany wouldn't have "joined forces" with Russia.

Yeah, the war might have ended differently if they hadn't invaded Russia and if the US didn't make Germany fight a three front war.

You're saying here that the US made Germany fight a three front war.

I don't know if that's what you meant to say, but it is what you're saying.

Could you explain what you mean please?

What three fronts are you refering to?

Thanks.

In reality, the possibility is as big as the possibility of Germany beating USSR, meaning small (which was the condition I presented before the "joint force" suggestion). I thought we're just talking about hypothetical situations here. That's the only hypothetical situation I can think of that can possibly survive a war against the US in US soil.

Okay.

I can live with that.

Sorry I was being overly analytical.

Interesting deviation from the topic: could it have been possible if Hitler had been assassinated earlier in the war (addendum: possible removal of Göring) and his generals direct much of the war? The Eastern Front was a disaster that made, even from 1943, the defeat of Germany a matter of time.

I don't know as I'm not much of an alternate history junkie (more of a lurker on their main forum). Anyone have any ideas of a possible path from that deviation that could have led to a Nazi victory?
