That's not really a question I have the expertise to answer. There are a lot of people here who have more.
Obviously, we should be pulling the stuff out of the ground ourselves and processing it here. Experts may have a better take on that than me, but that just strikes me as a no-brainer in terms of maintaining the integrity of our ability to avoid being subject to coercion by autocratic states. They might have things we need for our development, and they would be prepared to withdraw them—as they did with Japan in 2010, as I said—to coerce us into giving concessions in other areas.
