No fan of Ike, but since his higher ups had already determined that Berlin area would be part of the Soviet occupation zone, Eisenhower correctly decided that American men and materials should not be wasted in taking territory which their political overseers already agreed would be turned over to Stalin.
Good point of which I overlooked. However, (as someone earlier in this thread stated), with perfect intelligence and hindsight I am easily on par with General Patton, Napoleon, and Genghis Khan when it comes to military strategy. :)
