I think if Germany had completed Sea Lion and then captured the rest of Europe, and then built up a massive army with Rommel in command to invade Russia, i think the Riech could have pulled out a victory. In hindsight, its good they lost or else we'd all speaking German right now and living a terrible place. I only admire the Germans becuase they where able to build some of the greatest armies ever in such a short time. Also, how could anyone not think that Rommel was the best. I will admitt that Genghis Khan is better. Heres my top five military leaders of all time.
1. Genghis Khan
2. Erwin Rommel
3. George Patton
4. Tamerlane
5. Douglas MacArthur
Honorary Mention: Paul Von Lettow-Vorbeck
Vorbeck was a WWI German commander in Africa who beat back British armies almost three times his size

-Mannerhiem also was pretty good
