Because most people aren't willing to come right out and say, Israel is JUST AS GUILTY, as the Palestinians, for causing all of the problems over there....because they are. It doesn't really seem to go over well, when you point out all of the flaws, and stupidity that has resulted from Americas intervention, and divisions of land, but when you bring up Israel, the moment a criticism is brought up, it goes straight back to the holocaust, and a reminder of the atrocities suffered. From there it manifests it self in guilt, and a desire to avoid ANYTHING even slightly controversial in the region, that might not shed the best light on our allies....and friendly little puppet string pulling campaign donators.
