North Korea is pushing for a peace treaty with the U.S. in what skeptics call a bid to get the U.S. out of the way so Pyongyang can invade the South. While the conventional wisdom has been that the South would use its superior technology to wipe the floor with the North in any armed conflict, those predictions are overblown. In a worst case scenario, the North would kill civilians in droves and wipe entire neighborhoods in Seoul off the map. While the South would likely ultimately win, it would pay a high price.
