preemtive strike means all of the options have to be on the table. but we have to understand the consequences. seoul is closer to the north korea border than washington is to baltimore. i mean, it is very close. and it is a city of 25 million people. it could be attacked drastically and dramatically just by artillery. you don't need jets, jet airplanes, bombs or nuclear weapons. the deaths and destruction would be enormous and of course japan is a close neighbor. so while we want north korea to understand that there is overwhelming military force, i much prefer a tightening pressure diplomatically. that is really the preferred solution. the other question, wolf, is if you did some kind of preemtive strike, could you destroy their nuclear capability?
