Egypt already has syrian refugees and subsaharan refugees in addition to the recent influx because of the sudanese civil war.

Either way, the current regime violently overthrew, imprisoned, tortured and eventually killed the democratically elected previous regime which has ties and many many sympathizers in Gaza. Meaning that the cocksucking son of a removed sisi will never let them in, because he's afraid of another revolution

Plus leaked talks from Mubarak (two egyptian presidents ago) literally have bibi pointing at gaza and saying i want to move them elsewhere and pointed at sinai. If Palestinians go to sinai they are never coming home.

Not to mention that ISIS is in sinai....
