The United States should withdraw from the UN. The UN should be summarily ejected from the United States and deposited somewhere in LaLaland, either the netherlands or belgium. the next step would be to knock out all of korea's infrastructure with conventional weapons. that could be accomplished with a single CG. but the first step would be to privately warn china that we would pull out of their economy if they even squeak a disagreement. if the chinese get huffy then there's always the three gorges dam that could be bombed.
