We could produce all the oil we need for the foreseeable future. we just need politicians to get out of the way.
I think the opposite of your fear for isolationism is what we are dealing with today. we are TOO integrated into the world's business. there is no reason we should care about some of these regional conflicts. there is no reason we should be getting involved into EVERY conflict that pops up. we don't need to go full isolationist, but IMO we do need to take a couple good steps backwards. Take care of our own issues for once, find out who our actual friends are and who is actually a good partner to have on the world stage. We are so integrated that people, including our own citizens, take us for granted and don't realize the true implications of our involvement. simply because that is all they have known.
