Massive artillery barrage on Seoul, funneled troops including SOF push south, potential nuclear ICBM launches on Seoul, Tokyo, Pusan, US west coast. We know where they have some toys but not all of the chest, let me put it that way. 30 to 40,000 KIA within the first two hours. Guaranteed NK retaliation via the methods above and maybe chem/bio launches, insurgency. Bad stuff Higgins but the US and SK would win it in the end.
All of the above. I think that they may be more hesitant to use nukes than other WMD, since we would retaliate in kind and in force, but the point here is that any conflict would be prolonged and extremely bloody.
