One of the most controversial issues surrounding how UNRWA does business is its fast-and-loose definition of refugees, which has kept expanding over the years.
When
UN General Assembly Resolution 393 was passed on December 2, 1950, endorsing UNRWA's purpose, it clearly stated:
[T]he reintegration of the refugees into the economic life of the Near East, either by repatriation or resettlement, is essential in preparation for the time when international assistance is no longer available, and for the realization of conditions of peace and stability in the area
UNRWA's job was to either repatriate refugees, where possible -- or to resettle them
elsewhere, with the realization and acknowledgment that the money was not going to last forever.
But that goal was only good for about 10 years.
