User blog comment:PitaKang/Funday Monday 2: Could South Korea defeat a North Korean invasion?/@comment-5883269-20130425164344

In pure military term, leaving not foreing aid for either side(i count american troops in Korea as 'korean' because they're on soil), the north only have the factor of 'surprise' of the first attack, in long term the south can defeat the north in a open invasion.

Much of the military doctrine of the north is pretty obsolete, and even with their weapon they would have to go now to urban warfare, a warfare they're not trained to go, a war will damage economically the south worse that 1997 financial crisis but those damage can be keep,more that north strategy is not to destroy the south.
