I think the idea is great, however I believe that it's a negotiation tactic. I believe Trump wants, say Egypt and Saudi Arabia to take over Gaza...but they don't really want that. They probably don't want a US owned state there either, so maybe they'll offer an alternative. That being said, I would fully support such a move, as long as the Gaza citizens are moved to, say Egypt. After all, they've proven that they can't play well with others. And it ain't done in Greenland. Trump could easily offer Greenland citizens an economic offer that they will take. Hell, there's only 60,000 of 'em.
How much tarrifs are we charging Mexico and Canada? I called it and our resident Liberals were wrong...again. Trump is using leverage to get better trade deals, which is very confusing to Libs.
