The problem the US and Russia have is how to dispose of vast stockpiles of unneeded weapons grade materials.
Raw uranium out of a mine or even slightly enriched uranium for power reactor applications are not proliferation threats.
The simple problem is US competitiveness. What are we doing, not mining enriching and using our own uranium for our own power applications and to supply other countries who have the proper safeguards?
This is not a security issue. It is an economics issue.
We are too dumb (americans in general, liberals specifically) to realize that nuclear power is a great way to reduce our foreign energy dependance.
We should be harnessing the power of the atom instead of cowering in fear from it under our desks like children of the 1950’s during a duck and cover drill.
