I'd like to hear your take on this.
This is one of the very, very, very few subjects Boilerboob actually knows something about, so his asking the question is dishonest and disingenuous.
We import "sweet" crude oil, primarily from Canada, because much of our existing supply is "sour." The term refers to sulfur content. It's easier and faster to refine sweet crude. Furthermore, Canadian oil is very often physically closer to our refineries than domestic oil. So we import from them as a matter of utility and convenience.
It was the same way during the "Arab oil embargoes." We could always have met domestic demand with domestic production alone. But the oil companies preferred the sweet crude we could get abroad. And when that source was abruptly shut down, they didn't have the ability to immediately ramp up domestic production.
So the existing Canada-US relationship was set up, with the reeasonable assumption that neither country was going to use oil supply as a coercive tactic or weapon of war against the other. But of course, no one saw Trump coming.
