If we created demand for Thorium, we could solve the energy and rare-earth problems with one blow. There is a kind of rare earth ore that we could mine profitably, if there was only something to do with the Thorium.
A thorium market would open up development of Monazite sands, which right now are uneconomic because of the cost of thorium disposal. This would give the US a supply of rare earths as well as solving global warming without introducing nuclear proliferation risk. The same technology could also be used to reduce the lifetime of radioactive waste from 10's of thousands of years to under 300.
