The Big One

A alternate history universe created by Stuart Slade where Nazi Germany loses WWII, despite managing to successfully invade England and take Moscow.

Is highly controversial, due to the method in which Nazi Germany loses the war; namely, just about every large population center in Germany being hit by nuclear weapons carried by B-36s, resulting in 20~ million casualties alone from the attacks themselves, with a further 40~ or so million casualties from the after-effects of the attack.
