If N.K. popped a nuke up into the air around 200 miles and detonated it over Russia or China it would have devastating results from the EMP effect. the same would go for us too if they launched one off each coast and off the gulf it would take two minutes and we'd be back in the pre electric days. It would fry our electric grid along with every electric system here. We would be in total social breakdown in 30 days.
