Trump's proposal only emboldens extremists in the Israeli government, thus why the Biden admin. was against such a move. Furthermore, relocating Palestinians from Gaza could destabilize Jordan and Egypt, two critical US allies in the region. As the tensions remain high, it is imperative that the cease-fire holds.
Trump understands that as long as Hamas and other radical Islamist groups remain on Israel's doorstep, there will always be more conflict and misery. Trump's suggestion to relocate the Palestinians is a move of compassion that would both ensure the safety of civilians and Israel's security.
Only the most ill-informed of people do not recognize that Trump's suggestion equates to the forcible deportation and ethnic cleansing of Palestinians — violating fundamental tenets of international law and the Geneva Conventions. Indeed, this was the plan all along, as even the Biden admin. floated the idea of forcibly displacing Palestinians from Gaza.
