Germany could never have invaded the U.S and won, dude...Do you realize the logistical nightmare? They'd have to first and foremost subdue the U.S.S.R, which would have been nigh-impossible (though possible)...then they'd have to vanquish the British Empire. Britain may have fallen, but her Empire was prepared to fight on forever. Then they'd have to take on Africa, which probably wouldn't have been too difficult, but still a serious challenge. Then, while ruling all these new territories and somehow keeping them all secure in the face of GUARANTEED insurrections on a monumental scale, they'd have to scrape together a navy and enough manpower to take on two of the most populous, resource-rich, and easily defended continents on the planet. The United States populace would absolutely be on the warpath long before this ever happened, and Congress would have declared war whether Lindbergh liked it or not.
This notion that Germany could ever have taken over the world is fantasy.
