"so what? We launched a nuclear raid on Japan but it'd be impossible against the ALL POWERFUL NAZI'S? Besides, we'd still have French resistance, British resistance, Australian help, and Canadian help in defending. Not to mention the Russians, but since Germany can produce V4's in instants yet tanks in days they could nuke the whole world huh? Sorry, but my American pride tells me Nazi's wouldn't have won."
The difference is the German bombers had a superior range then the American. With the British surrender once Hitler invade London (like his generals suggested) would mean the Americans would have no air bases within range of Nazi Germany. There was a reason that it wasn't until 1944 that America didn't start bombing Japan. That reason was their bombers didn't have the range to do so until then.
"The Germans were doomed from the outset of WW2. They never had a chance of defeating Russia, and certainly not the USA. Despite their determination, discipline, organization, technical skills etc, they did not have the necessary resources. The war could have gone on and on, but the Germans would have run of gas, while the Russians had plenty."
That was the whole reason for invading Russia, they needed Russia's resources.
but had Russian been an axis nation...
Also look at Operation Barbarossa. It was succeeding before Hitler tried encircling Kiev rather then by passing the city. Had they enter Moscow in August, which they could have, Stalin would have been captured by the Germans pushing the Soviet Union into Capitulation.
"In October and November 1940, German–Soviet Axis talks occurred concerning the Soviet Union's potential entry as a fourth Axis Power. The negotiations included a two day Berlin conference between Soviet Foreign Minister Vyacheslav Molotov, Adolf Hitler and German Foreign Minister Joachim von Ribbentrop, followed by both countries trading written proposed agreements. Germany never responded to a November 25, 1940, Soviet proposal leaving the negotiations unresolved."

The Germans were not doomed from the outset. Given the superior discipline, technology, generals etc.
