I think Trump has done use a favor. By refusing to help the Saudis with their war, they've joined the "Mecca agreement", and now the US has zero leverage in the Middle East.

Which is something the Left has been trying to accomplish for decades. "No more blood for oil!" they shouted. OK, done. We'll *have* to go with renewables, because we can no longer strong-arm cheap oil out of them.

And Shell Oil can look forward to closing up shop in the next decade or so.
