You are correct Bob, that nothing happens by accident in the great scheme of things; but as for the Arabs being commanded by God to squat on Israeli land, no -- their god did not tell them to do so. Qur'an says nothing about specifically settling the land of the Jews, except as part of their commandment of universal conquest. In fact, the author of Qur'an commands that they stop worshiping toward Jerusalem, and bow instead toward Mecca.
I give the Arabs credit, by the way, for fighting for their land. There is nothing unnatural about that. What's utterly eerie, though, is the obsession of the rest of the world with driving the Jews into the sea.
