Perhaps the loonies in the 50s/60s who kicked the Arabs of their land and created huge refugee populations in adjoining countries could pack their bags, yes. At least back to recognised international frontiers anyway.
Israel never learned to coexist, it was and still is a young country, perhaps one day it may grow up.
Are you referring to the refugee camps in Lebanon/Jordan/Syria? Countries that will not absorb them and leave them to rot in UN Camps?
Jordan who revoked the dual nationality passports of all Palestinians?
Israels neighbors were and still are a horror show when it comes to genuine Palestinian refugees.
