Israel is being the very opposite of a force for stability in the region, which isn’t going to help the Petro-Dollar.

Israel being a destabilizing force gives the US leverage over the oil rich nations of the region. That’s why Israel is important for the petrodollar. I’m also not sure the US currently has a way to maintain its global economic dominance without the petrodollar. That’s in part why I think you see the US doubling down on support for Israel even in a context where doing so is increasingly risky.
