Fortunately there is difference between creating deadly virus or bacteria and weaponizing it. Effective weaponization requires stabilization. Biwoweapon must survive in the environment and there must good delivery mechanism. Creating epidemic requires optimizing the delivery, contagiousness and symptoms. It seems that North Korea has remote islands dedicated to bioweapon development and testing. Biosafety level 4 laboratories are must if your researches go to home each night. But if you can do the most dangerous parts in islands where people are in quarantine and have prisoners to experiment with, it's easier. It's impossible to know how well they have weaponized their bioweapons. Description of North Korea’s BW Program from ROK Parliamentary Audit 2015: >North Korea has 13 types of biological weapons in the form of agents, and it can cultivate and weap- onize them within ten days. In an emergency, it is likely that the North would prioritize using anthrax which is highly fatal and smallpox which is highly contagious. Special forces, airplanes, and contam- inated carcasses are the potential delivery means. It appears that the North has not developed missile warheads with BW payload.
