Retop, those who say this doesn't worry them say that not because 1kt is small, but because even if it had been 100kt, they don' t think that the North Koreans have the will or ability to actually hit us with one of them. In fact, a couple people are arguing that nuclear arms are the unalienable right of any soveriegn state.
I'd have to agree with you. No enemy, in the modern day and age, is worth underestimating.
