The many what ifs. What if Germany had treated Jews well, and the many Jewish scientists involved in the atomic bomb program had stayed in Germany. Could Germany have developed the bomb first. What if Germany had not invaded the Soviet Union. Or more possibly, what if Germany had treated the Ukraines, Georgians, etc decently so that these populations rallied to the Germans. What if Germany wooed Spain to the point where Spain captured Gibraltar and helped closed the Mediterranean to the British. Heck, what if the Normans were repelled in 1066.

We really need to find Star Trek alternate universes where such events actually happened just to find out the results.
