Yeah, if the Muslim world were able to successfully vanquish Israel and the west, people would look at them as the vanguard of civilization rather than a bunch of barbaric towelheads. The headtowel would be viewed as the symbol of civilization, kinda like a suit and tie.
It really just depends on who's able to come up with a bunch of scientific, technological, and cultural advancements; Mises pointed out that the Ottoman Empire didn't accomplish a lot, despite their conquests, which I don't know the truth of but we don't hear too much about them in history class.
