That will be a tough job. We import more oil that we produce ourselves. How is he going to get supply from Saudi Arabia, Canada, etc?
Were recovery, refining, and distribution, nationalized the amount we import would go down dramatically as a way to force alternatives on people.
I don't know whether Barry and his crowd want to be just like their third world heroes and nationalize the oil industry. I do know that I was answering someone who seems to think that may be the goal. If that's the goal, I think a series of steps would be taken first.
