My point is that any american that proclaims moral authority to condemn israel purely on the fact that a palestinian state once existed there is not grounded in our own reality.

I do not accept your premiss that Israelis murder Palestinian children. Its kinda like saying the flotilla was really on a peaceful aide mission (pay no attention to the big lead pipes).

Additionally you are (whether or not you know it) straying from an intellectual question about claim to land by israel and palestine by ignoring the points in the OP.

So why don't you demand jordan, syria, and lebanon cough up some land for the righteous owners?
