North Korea

Researchers at Harvard's Belfer Center scoured the globe for whatever was publicly available on North Korea's biological weapons program. Referencing news articles, journal papers, expert interviews and government reports, the team assembled a comprehensive study of the knowns and unknowns. Here are the main findings.
Winston Churchill once said that Russia is "a riddle, wrapped in a mystery, inside an enigma." That's in many ways still true. However, Russia is a complete open book compared to the Hermit Kingdom. The latest development in the ongoing saga of North Korea is Kim Jong-Un's threat to attack Guam. If he was capable of that (and he very well might be), would he actually do it?
Did the North Korean regime hire former Soviet scientists to build a biological weapons program? Given what we know about both countries, the possibility cannot be ruled out.
