I'd like to go back to you, Mr. Marshall, for a minute. We're just about out of time.
On these rare earth elements, I agree with what you said in terms of where China is at and the control it has over the system. In your presentation, you mentioned the joint action plan between the United States and Canada. Is that basically the bottom line proposal for how we can get out of this risk, I guess, of not being able to attain rare earth elements? Or is that enough? What do you see as the bottom line solution here to lessen the risk to us with the monopoly, basically, that China has on these metals?
