No amount of money is going to change attitudes that severely without some sort of forced indoctrination. It didn't work with Hamas, their attitude was there from the start, and years of Israeli and Iranian funding has only helped them remain one of the major Palestinian political organisations.

And please, Israel is an apartheid state sure, no arguments here, but the Palestinian population is one of the fasted growing in the world. They are entirely at the mercy of the Israeli state, and if the Israeli goal were to exterminate them as you say, they would have had some results in the past seventy years.
