I think the crowd that loses their mind over every Trump quote, usually cannot see he has an end goal he is trying to achieve. These goals(policy shifts) are not usually attainable through "traditional diplomacy". Trump does let some clues slip as to his end game in these scenarios.
My guess at this point:
Trump has been pressuring (hard) the wealthier players in the area to take(resettle) Palestinians they do not want. These players would probably rather part with some money than take people that are slightly brainwashed to cause havoc. So, Trump shifts course yesterday and suggests we rebuild Gaza. He didn't say we would pay for it and at one point sounded like he would be asking others to pay for it.
So, I would guess he is trying to get "donations" to help settle the rebuild and placement problems over there in the name of peace and humanity.
It would not surprise me to see US troops handling security and US contractors participating in the rebuild and all for a reasonablefee.
Of course, this is speculation on my part. The crazies can go back to the gnashing of their teeth🤣
