What is the appropriate role of the government in ensuring the availability of critical materials for US industry and the defense sector?
Advancing technology creates ever great demands on materials with highly specific properties. The rare earth elements are a case in point, where China currently controls 97% of the world's production. There are clear risks from such reliance on a single source for materials that are critical to particular technologies. What can and should the US government do to address this vulnerability?
