It probably is something Trump would try if he got back into power. Cautioning that eventually Israel would have to pay up in whatever denigrating way he would want.
He actually strikes me as very pro-Israel given that he recognized Jerusalem as the capital, which was controversial when he did it and moved the embassy there. Your post seems to imply he is antisemitic and would exact some kind of humiliating capitulation of sorts on them; what evidence is there for that with him, specifically with regard to Israel?
