I can't think of a single Palestinian leader or spokesperson who has NOT called for the destruction of Israel. Leaders on this side simply do not exist.
And if a Palestinian state is created, I'm revising my list on the countries most likely to be hit by nuclear weapons in the next 10 years. Once a state is created, they have the right to arm themselves. Once they arm themselves and become a bigger threat to Israel, which they have vowed to destroy, Israel will take them out. A Palestinian state won't last very long.
Just because you say the way he describes Palestinians also can be ascribed to X, does NOT make it so. It also does not make him so. Palestine doesn't exist yet so you must realize those who call themselves Palestinians did come from somewhere. They are not welcome to return to Syria and Jordan so they are stuck, being used as pawns by the Arab world. Another way to look at it is that they are all inbred and on drugs and being fed lies until they have nothing to live for but to commit suicide for some cause. Their leader is misleading them and that has become Israel's problem unfortunately. War sucks!
