I think it’s just purely profit-motive without any form of long term strategy. Israel and Ukraine both justify printing money to give to arms manufacturers. Ukraine sold off its public infrastructure to American private investors, and Israel is already making plans to redevelop the Gaza Strip, presumably financed by American real estate companies. If Biden is still in office when Israel runs out of speculative assets to sell off, I assume his admin will find some other ally to prop up while gutting.
