Here's what i think after we're done with the Taliban,and we eliminate Saddam from power,I say we go after North Korea and stop them before they get started.I don't what's holding us back.We need to act quickly before they start firing off nukes.
As soon as we act or give the impression that we are going to act, Seoul gits lit up like the fourth of july. That is why we aren't going to act. To defeat the north, the US would need to mobilize a very large army much greater than it currently has in the DMZ. As a result, we will settle this through diplomatic means. Even though N.K. lied last time and pissed on their agreement, we will make them agree this time not to do that. Its really just appeasement. If push comes to shove, China does not want US warheads sitting in S. Korea. They will do everything in their power to convince No. Korea.
