Can Palestinians leave Gaza voluntarily?
This was interesting. As I mentioned in the comments, the Israeli government has a new department dedicated to "voluntary" departure of Palestinians to other countries in the world. I don't think starving people, under bombardment, have any kind of realistic consent, especially when lacking a right of return. So, I'd say no.
Bibi still has to come up with about six million so he too, can pay off El Salvador to take Palestinians..............
@LaNaehForaday El Salvador's current authoritarian president is part of the Palestinian diaspora. I'm not sure what that would mean for your proposal.
