An export ban would keep US prices down, but also cause global prices to rise faster and higher. That's not great for both the wars against Russia and Iran - the rest of the world might decide it doesn't make sense to cooperate with the US anymore if the US isn't providing them with fuel. Then on top of that it might trigger a global recession; diesel is the blood of logistics networks.

Critical support for Trump's green new deal I guess. 😹

Hell yea. Though this is just talk, too many shitty people make too much money in the energy market to go along with what the mad king says on this one.
