I’ve asked myself the same question over and over. This one does a good job of exploring the issue. This one is the what no one seems to want to face:
Well, for one thing, the hothouse logic of the Palestinian-Israeli conflict is surely spilling over into this one. For decades, Arab governments and the newspapers they control have been pouring gasoline on the fire of Arab resentment toward Israel as a way to deflect attention from their own corrupt and impoverished regimes. No doubt, there are Palestinians with serious and legitimate grievances against Israel (and vice versa) but Arabs in Syria, Egypt, Yemen, Saudi Arabia, etc., who have no plans ever to visit historic Palestine, have no relatives there, and, were it not for the presence of Jews there, would not care about the plight of the Palestinians at all, have been convinced that their problems can be attributed to the oppression of the Palestinians. The Palestinians are the Sudenten Germans for any number of dictatorial regimes, beginning with Iraq.
