I have heard that Roosevelt let us be drawn into WWII because it was necessary in order to defeat the German Nazis. They had pretty much taken over Europe and had Great Britain on the ropes. If the US hadn't gotten involved, Hitler could have conquered the world.
Germany would have no problem taking England but they made a big mistake they attacked Russia using up all their energy there and were unable to keep fighting. The Russian and not the US took the biggest tole on Germany
But Russia was largely supplied by the U.S. They had good tanks and lots of people, but they couldn't make a truck, and I think they had trouble making airplanes. If the Japanese had held out a few more months, and Hitler had not invaded Russia (the USSR then), most of the world would no be under some form of German domination. Watch "The Man in the High Castle" on Amazon for a taste of what that could have been like.
The question is not so much about whether Germany was capable of capturing Britain because Hitler was not as much interested in invading Britain as he was in invading Russia. When he realised that he was no longer given a free hand by the West, he felt a need to try and conquer Britain just as he had conquered France in order to lower the risk of a second front being opened behind his back when turning against Russia. Based on that strategy, the resources he was willing to use in a war against Britain had to be limited since he needed them when attacking Russia, which had always been his main goal. In his own vicious logic invading Russia was the thing for him to do. He blatantly misjudged the strength of the Russian army.
Sorry but the RAF blew the German Airforce out of the skies and the British Navy destroyed their landing forces. All this was in Sept 1940 We defeated the Germans then, they gave up and invaded Russia the next year. We had won are war then.
PS 9 Americans joined the RAF and fought in the Battle of Britain in 1940. They lied and stated they we Candian...as Americans that they would be considered traitors if the fought Germany on the side of the British. Of thoses nine eight died. Quote.... In the summer of 1940 the Second World War had been under way for nearly a year. Hitler’s Germany was triumphant. The United States was neutral. It was a time, Winston Churchill later observed, when “the British people held the fort alone till those who hitherto had been half blind were half ready.” Some Americans, however, did not remain on the sidelines. That summer and fall, eight American pilots fought against the Nazis in the Battle of Britain. This remarkable bunch of rogue flyers included ex-barnstormers, a Minnesota farm boy, and the greatest bobsled champion in American Olympic history. All had defied strict neutrality laws—thereby risking loss of their citizenship and imprisonment if they dared return home—in order to join what they regarded as the best flying club in the world: Britain’s Royal Air Force.

Don had already pointed at the German Luftwaffe. Goering was a big mouth. General winter helped the Russians but was not decisive for the outcome of the war. They'd have won the war anyway with the help of the allies. What was telling, though, was not the winter itself, which was expectable, but Hitler's hubris which made him believe that "the German troops will be back home at Christmas which they can celebrate with their families". Consequently, winter equipment and uniforms were not handed out to the troops.
@Thomas Stearn Your obvious consternation here is very acceptable.The British fought valiantly, as did others from around the globe. I suspect that, with a bit of support from US production of heavy bombers, Britain may very well have staved off Hitler's aggression using US supplied heavy bombers. In any event, the US ability to produce extremely large numbers of heavy bombers undoubtedly tipped the scales. Frank
