Israel doesn’t practice “do unto others as you would have others do unto you”  But “do to others what others did to you” The problem is the others in their case are the easiest target at hand that has anything of value and that’s land

During much of 1948, Palestinians driven from their homes by the violence of that terrible year took safety in what could reasonably be called refugee camps; camps for people who have fled ongoing violence or natural disaster and are unable or fearful to return. They ceased to be refugee camps by January, 1949.
