What scares me is that North Korea did test what is known as an atomic demolition munition with a yield around 1 kT. Even at 1 kT, you detonate such a bomb in a dense downtown of any major American city and you could kill 80,000 to 100,000 people immediately from the blast and immediate radiation effects and maybe another 100,000 more from delayed radiation sickness effects. Also, because the bomb is detonated at ground level, it will kick up a huge amount of lethally radioactive fallout and the crater left from the explosion will also be lethally radioactive for decades (think the Chernobyl disaster but many times worse).
