at no point he was saying that gazans will be rounded up and moved out.
the way that conversation is going now is (and i am not trump fan):
- everybody: gaza is destroyed and nobody can live there. conditions are inhumane
- trump: lets allow to people move out to different countries, provide them with housing/jobs/etc while gaza is rebuild
- israel: we will help to people who want to leave - to leave
- everybody: this is literal genocide and ethnic cleansing. gazans should stay in gaza
A US administration that was serious about this would propose a deal to take some refugees from Gaza as a sign of good will. Something like "we will take 25% if other countries agree to take 75%." To say that other countries should take all the refugees, when they've shown no interest in it, is deeply cynical. So I didn't bother to look further.
Of course we'd never see that from the Trump administration. Unfortunately the Biden administration wasn't imaginative enough to suggest such a thing.
i saw some interviews with gazans that said, that in case EU/USA/Canada will accept refugees, Gaza will become empty overnight.
Legal restrictions could be reduced if there are any counties willing to take refugees.
