It is very naive to think the Palestinians would not reject the proposal as they get nothing. Kushner and Trump never asked the Palestinians what they wanted. If you don’t know what each side’s goals and wants are, and what are immutable “no’s” you can’t ever reach a compromise. There is a science snd art in doing that. I am not aware of any examples in history in which either Kushner nor Trump were ever successful at really negotiating a compromise. That they thought they could (if that is true, and not just a political ploy to support Netanyahu) shows their naïveté and arrogance.
