As far as anyone with any knowledge of history is concerned Israel not only has the right to exist on its current land but so much more.
It is the Palestinians that re the Arab intruders.
Furthermore,Israel is a modern,functioning,moral democracy that has made great unilateral concessions in the name of peace including the removal of its own people from the Gaza strip and the territory handed to the shiftless,parasitic "palestinians" who thank the gesture with roacket and mortar attacks.
If the refugees are not content,then they should seek a better life in other Arab states that incidentally want nothing to do with them as long as they can be used as pawns in the propaganda war against Israel.
Failing this,the refugees should consider ceasing the brainwashing of their children into mindless jihadists and instead become a partner for peace with Israel.
