The United States of America has no right to be in any location of the Korean Peninsula. One of the reasons North Korea is in such an authoritarian state is because the United States keeps on threatening them with the continuing presence of military occupation in South Korea. This is in addition to the occupation of the Korean Peninsula being too expensive to maintain. As evil as Kim Jong-Un is, he has good reason to fear the United States. North Korea didn't drop nuclear bombs on an adversarial country. The United States did. North Korea isn't waging war on democratic governments throughout the world. The United States is. North Korea doesn't have an overwhelming military presence throughout the entire world. The United States does. If we want diplomacy with North Korea to work then the USA needs to be more friendly. We can start doing that by withdrawing our troops from the Korean Peninsula and show Kim Jong-Un that we can have a nuclear free world if we PEACEFULLY cooperate with each other.
