His message is simple: Nuclear weapons are not a force of nature, and they are not an act of god. We have built these with our own hands, and we know how to take them apart.

Working as partners, one-time enemy researchers made breakthroughs they couldn’t have achieved alone.

For the first time in years, there is some welcome news out of North Korea: Washington and Pyongyang have finally struck a deal. North Korea agreed, for the time being, to issue a moratorium on uranium enrichment as well as nuclear and missile tests, which would help relieve tensions on the Korean Peninsula.

I had been informally offered a job as the associate historian of the U.S. Nuclear Regulatory Commission (NRC) but was still waiting for the final paperwork to be processed.

But the treaty does more than this -- it also has a health benefit. Put quite simply: No more tests, no more fallout.
