I don’t think it’s straightforward land grabbing.
I think it relates to the work of the early neocons in the 1990s/early 2000s bearing fruit at a distance in time. Key figures in the Bush administration advocated for the US to be a global hegemony. Other neocons who were associated with them worked with Netanyahu in drawing up the “Clean break” report-Israel would dominate and destabilise the surrounding Arab states that represented a threat, work towards regime change in Iraq and and would become more self reliant in its relationship with the US.
Now the neocons are back. The right is rising everywhere, not just the US .
i think Trump wants to throw NATO under the bus. I think he would like to have control of overseas territories that have key shipping routes- Greenland, Panama Canal and either the Suez or a new Ben Gurian canal, but ortwise take an isolationist approach. He would get Israel to do any dirty work for him- no US boots on the ground, Israel would do the ethnic cleansing and be the regional power- it’s crossed so many red lines it can literally get away with mass murder without a regime change, there’s an appetite for revenge and Palestinians have been systematically dehumanised in Israeli public consciousness.israel has or will have nuclear capabilities soon.
I’m not saying that he’ll achieve it, I’m just saying that it’s not about golf courses and beachside hotels. And if you disregard the ethics and the feasibility issues, it makes the idea of buying Gaza less crazy
