Not only to the United States, but also to the rest of the world, North Korea could be a real threat because of the dictatorship of one dinasty. United States and other world leaders have to stop challenging North Korea with meaningless military exercises near North Korea border. They have to do everything to sit with North Korea leader and talk with him. China could have very important role since they are one of rare allies of North Korea, but that won't last for much long and something has to be done before it is too late.
Yes, North Korea is capable of posing a real threat to the United States because they have nuclear weapons. If they could get one of those weapons to U.S. soil without detection, they could kill millions of innocent Americans. In addition, North Korea could harm allies of the United States, which would have consequences or international peace.
Yes, North Korea is capable of posing a real threat to the United States based on several factors: economics, technology, and allies.

Yes, North Korea is capable of posing a real threat to the United States if they continue to develop nuclear weapons. The US should be very careful and not dismiss North Korea as weak. Their leader is insane and wants nothing more than to destroy the west. We must keep our eyes on them.
A Juche country (NK) has no hope with the economic destitution that their failed ideology has brought about. Their army is woefully under, their nukes are pathetic and they're essentially China's weird little lapdog with no real influence over anything. If they had a more efficient economy perhaps, but as it is they're under prepared for war
