 We're also working on partnerships with friendly countries so that when we do need to turn abroad for materials or refinement, we're not necessarily turning to places like China. And increasingly, recycling will be important. Some of these materials live indefinitely. Thank you. Let me drill down on that. Would you be part of a group of voices that would say we need to mine these products in this country instead of somewhere else? I certainly would prefer that they be sourced domestically.
