It is not that difficult. Have the UN proclaim that Palestine has been returned to the Palestinians and the descendent's of the Semitic Jews who lived there, and withdraw all support from 'Israel'. The immigrant Jews, who after all immigrated to Israel knowing that they were taking up stolen land and possessions, could migrate to any of those country/s that would take them. Harsh? Not anywhere near as harsh as the Nakba and the horrors inflicted upon the Palestinian people over these long years.
