I do not believe that Israel has the responsibility or the capability to take care of or provide for the Arabs who now call themselves "Palestinians." Israel has won control of a certain amount of land in the course of defending itself from external attacks. It has given much of this land back to the attackers even though it could be argued that the land was part of the "true" historical Israel. The Arab refugees should have been resettled in Arab lands long ago. They are not really Israel's responsibility. The Arabs have kept them in a refugee status as a part of their attempt to destroy Israel.
