re: #241 Ming

This is really a tragedy. I assume technologies to make nukes will continue to improve, e.g. precision manufacturing, even 3D printing of some parts. Putin has made the world much more dangerous.

The main industrial constraint that holds back nuclear proliferation is the actual possession and enrichment of the fissile material itself, which is a scale-of-high-tech-infrastructure sort of problem. 3D printers and the like are not likely to meaningfully change this situation.
