Their fellow Jordanians and other Araqbs.
It was they who turned them away at their borders in 1947 — knowing that their population would grow in numbers and viciousness after decades in refugee camps.
Who are these “Palestinians”? There’s no country of palestine?
The Palis have indeed long since turned into a pack of vicious murderers who receive nurturing in hatred along with their mothers’ milk. They are death cultists in a religion that already worships violence against “infidels”.
As such not even their fellow Arab Muslims want them. Palis are regarded as a plague & a curse by the governments of Egypt, Jordan, Lebanon, Syria, Iraq and anywhere else they attempt to settle. Keep ‘em in the camps, the Arab League has said since 1948, and when handling them point them away from you and at the Israelis like the mad dogs they are.
Palis are a dangerous but still useful weapon against the hated Jews, and that’s all they’re really good for.
