Endless War

The benefits are entirely "controlling global oil prices/supply". With the US all-in on climate terrorism, control of Israel helps control regional powers that also profit from climate destroying energy and delaying transition.

So, the only benefit is not an actual human sustainability benefit. It's an extreme cost.

The more obvious direct costs are paying for all the weapons, and the resentment that will lead to terrorism against Israel's allies. The fascism directed against those who protest genocide, is furthermore a step towards more intense fascism.
