I agree that the US and the world wouldn't support the killing or deportation of all of the Arabs west of the Jordan River who are not Israeli citizens, nor should they. Beyond that, your assertion/accusation is utter nonsense (like the rest of the bilge that you've spouted on this thread).
If the Israelis themselves would be satisfied to live at peace alongside the so-called Palestinians (and they would be - they've dreamed of it since before the State of Israel even came into existence), then who would I be to object? The problem, however, is that the murderous thugs who pose as the leaders of these Arabs are unwilling to do so. They want it all, everything from "the River to the Sea" (i.e. from the Jordan to the Mediterranean).
Some situations cannot be resolved peacefully. For example, nothing in the historical record suggests that there could have been a world in which Nazi Germany and Imperial Japan would have been able to co-exist with free and independent nations like England and the US. When it is an either/or choice, then a society must make the choice to prevail and survive, or it will perish. I hope that such is not Israel's choice, that the Arabs will finally choose to live with them in relative peace, but I fear not. Given the length of time that has passed since this conflict began, given the blind hatred, given the poisoning of the minds of young Arab children by the PLO and their like, it may be that no settlement is possible that would satisfy both sides. IF that is the case, and only if the choice is between Israel and a 22nd Arab nation, would I choose to back some extreme measure like deportation (but never a mass killing).
