Experts say a proposal to move all Palestinians out of Gaza and remake it as a U.S. territory would be time-consuming, extraordinarily costly and probably a violation of international law.

Western allies of the US and Israel are also against the idea.Some - perhaps many - Palestinians in Gaza might be tempted to get out if they had the chance. But even if a million left, close to 1.5m others would still be there.

In interviews, some Palestinians said they would rather leave Gaza, given the inescapable devastation — but the decision was theirs, not Trump’s, to make.
