JB, a long time has passed, individuals died, and the whole thing will be dealt with by statistics. I imagine every refugee family will get some fixed amount, depending on size, and those who can show ownership of some property will get an additional sum related to the value. As far as everybody's contribution, Israel will ask to take into account how many refugees from Arab lands it absorbed, and who is a refugee will also depend on the circumstances of departure. Also, what happened to their property. "Blame" here is too complicated for courts. I don't expect poor neighbors like Syria to contribute to the fund. Maybe Saudi Arabia will. The rest of the world will make all the "accounting" easy, because the warring countries will end up paying LESS than their fair share.
