UNRWA and anti semitism

There never was a historical people called Palestinians, except for Jewish peoples whose homeland was called that by Rome.
People calling themselves Palestinians now are related to Jordanians that lost in the Jordanian civil war.
They call themselves Palestinian partly because of the British Mandate for Palestine name. Jordan was the second state of the mandate. Israel was never meant to fracture to accommodate such.
UNRWA was created to accommodate Arab refugees. But, nowadays, UNRWA has gone native with terrorists, creating a multi generational refugee camp that is unique in the world. Where refugees are raised to hate and kill those helping them.
