I have worked closely with young educated Gazans on projects that outsourced to them. They claimed that they would love to get access to the Egyptian labor market, and get an Egyptian passport so that they could have a hope of working in other markets internationally. They’d leave Gaza for better opportunities elsewhere in a heartbeat. Yes, of course some other Gazans wouldn’t want to leave at all, and Hamas wouldn’t permit Egypt authority over the area. But Egypt’s refusal to open the borders to Gazans is about a series of security concerns of its own, and not so much about universal Gazan resistance to the idea.
Egypt's refusal to assist Israel is ethnically cleansing Gaza via forced deportation is a different issue than the one raised upthread about Egypt’s earlier refusal reoccupy Gaza.
Because, yes, the closures prior to the crisis, between the openings, have been due to Egyptian security concerns (mostly breakdowns of various agreements between Egypt, Hamas, PIJ, and the Palestinian Authority on border management), COVID-19, and various other issues.
Apartheid was different, it combined a version of the forced relocation and reservation system that the US used for Native Americans (only with the pretense -- with very little substance, but merely as an excuse for the central government to disclaim responsibility -- that the reservations ("bantustans") were independent states rather than territories of subordinate sovereigns) with the racial discrimination in services and facilities within the rest of the country proper that Black Americans faced in the Jim Crow era.
> Egypt used to own Gaza
Egypt occupied Gaza, the same as Israel later did, but did not claim it, establishing a separate protectorate (it was merged into the UAR with Egypt and Syria, and from which Syria later rebelled, but even then it was considered distinct from Egypt, and it was formally transferred to the authority of the PLO (though practical governance was exercised by Egypt) after 1964.
> Last I heard, Israel tried to get Egypt to take Gaza back.
Egypt can't take it back, because Egypt never claimed it.
The UAR can't take it back, because the UAR has been disbanded.
Egypt could reoccupy it, but why would they want to? (Especially given that the people there don't want Egypt to do so, and have been rather...prickly...about occupations imposed on them.)
