You claim that one civilization is superior to another in every way, and then accuse others of being racists and neo-Nazis.
Anyway, I find "What if?" threads rather silly, people in them seem a little to confident in their "what happens next" predictions for my taste. In my opinion it would be better to stick to immediate consequences, instead of making bold predictions for the next couple of millennia. There are too many things that will go differently, too many variables that will result in a world largely unrecognizable.
For all will know this particular deviation in history can result in world dominated by the Mongols; a ship reaching the Americas and exposing them to Old World diseases before large colonization effort can be mounted; European emigration to a economically more developed North Africa. Or, Bulgar Arabia, maybe the ERE was keeping them at bay, and not the Umayyads and the Abassids.
