I hope his idea is not to just plop the two communities together, but also integrate them. I listened to a podcast about a Muslim woman who married a Gazan Palestinian and went to live there eventually. She said they were very different from what she was used to. She worked in healthcare, had difficulty understanding their accent and just fitting in. Those people were under an embargo for years, so that explains the stagnation of everything.
Her grandmother was Palestinians, but I can’t remember if she grew up in the West Bank or Saudi Arabia.
