The following column first appeared in the Wall Street Journal: I met with President Trump recently to discuss American development of Afghanistan’s mineral deposits. Afghanistan owns one of the world’s richest untapped deposits of rare-earth and critical metals.

These materials are essential to green technology. A misconception in the environmental movement is that green technology eliminates mining. In fact it simply changes what you mine. You can’t build an electric car without neodymium and lanthanum, or produce solar or wind energy without indium and gallium.
