Arab and Palestinian leaders were primarily responsible for the Palestinian refugee crisis.
They caused the refugees’ short-term displacement:
They rejected the 1947 UN Partition Plan and waged a war on the Jewish state instead, serving as the source of the Nakba.
They encouraged Palestinians to get out of the way of advancing Arab armies and join the fighting, promising they would return after a victory that never came.
Arab propaganda manufactured or exaggerated tales of Israeli atrocities, causing widespread panic and more evacuation.
By adhering to the calls of Israel’s enemies, the Palestinians betrayed the state of Israel and forfeited their valid claim to the land.
They also caused the refugees’ long-term crisis:
Arab states refused to absorb the refugees or give them citizenship and equal rights (except for Jordan)
By doing so, they broke their ethical obligation to the refugees they created
They use Palestinians as pawns in their continuing war against Israel.
