Palestinians are the only case in the world where refugee status passes through generations and the only case where people can be both citizens and refugees(like in Jordan). in the middle of th 20th centuary the world was full of refugees, non of them exist today, they all got a new home. the only exception is ..... Palestinans. and why ? because the right of return is the ultimate weapon to destroy Israel. Peace will never have chance until the Palestinians will drop the "right of return" and all the refugees will become citizens of the countries they are in (Syria,Lebanon,Jordan & Palestine). So having a state called "Palestine" is the key to end they endless refugee status.
