The US mobilized over 10 MILLION troops for WWI, although only about 3 million were sent over to Europe before the war was over. Â That was about 1/3 of the POPULATION of Germany. Â They were even stronger for WWII, and while in 1939, Germany was stronger than the US, it didn't take long for the US to mobilize its forces in a way that would have overwhelmed the Germans. Â It's true that the US didn't need a strong military between the wars, because we have no enemies within range (or so we thought) but if Germany was our neighbor, we would have kept pace in terms of arms, because they would have been a threat. Â Even if they were on our border and invaded, conquering the US is almost imposslble in even the most optimistic scenario... the US is much larger than even European Russia, and our industrial base is widespread. Â This whole discussion is just ridiculous, this is like a war fantasy league.
The Russians defeated the Germans in WWII. Germany held nothing back when it attacked Russia on 22 June, 1941. It had nothing to fear from the Brits and the US was not yet in the war.The Germans destroyed 9 Russian armies (about 90 Russian divisions; 1,800,000 men) in 4 battles between June-October, 1941. Then, it began raining and the German tanks bogged down in the mud. Their army nearly got to Moscow, after the mud froze, by late November, 1941, but its had been already nearly freezing to death for 1-2 months. The Russians launched a huge counterattack on 5 December, 1941, TWO DAYS BEFORE Pearl Harbor took place, and the Germans nearly collapsed. It recovered largely by the following summer, but then really lost the war at Stalingrad in the fall-winter of 1942. Germany's final real effort to win was to try to rebuild again for the next summer, 1943, but it all ended for them at Kursk. After that, there was only retreat for the German army and no really large offensive again, as even the Battle of the Bulge was a rather weak effort on its part.
