They don't take refugees, because they are already not well-off economy wise. Having millions of refugees would cause their economy to collapse, and they don't have the capacity to feed them all and shelter them. They also can't ensure that every refugee is not a militant that would try to attack Israel back, from their borders, causing the IDF to lob bombs onto Egyptian territories.

Why are your trying to blame all Palestinians, like as if they are a monolith and all of them are troublemakers?
