Hitler could have not invaded Poland, with Stalin's unilateral invasion of Poland and the Baltics freaking the world out and allowing Hitler to rally everyone against him. Also, the United States would never have declared war on Germany without an extreme provocation like Pearl Harbor. Before Pearl Harbor, less than 1/5 of the United States supported entering World War 2. After Pearl Harbor, support for entering World War 2 jumped to 70-80%. As long as the Axis Powers tiptoe around the United States NO MATTER WHAT, they can keep them out of the war. And as long as the United States stays out of the actual fighting, Hitler's chances of victory remain pretty good. The technical and strategic issues that the Germans suffered (which were mentioned earlier in this thread) also need to be fixed to assure a German victory in World War 2.
@Resurgam I broke it up into paragraphs. Please read it and let me know what you think of it ASAP.
That's not an entirely true picture - US Public opinion changed rapidly between Sept 1939 and Dec 1941
Certainly earlier in the war the Polls showed a reluctance to get involved but only the May 1940 Poll shows a less than 1/5 ration you claim.
But as early as May 1941 over 2/3rds of Americans were pro getting involved in the war - this trend was increasing as time went on - and by Nov 1941 the USA was at war with German as it was possible to get without actually being at war.
It was only a matter of time and the USAs choosing before they joined the war
