North Korea is a threat to the United States. A lot of people forget that America was
previously involved in the Korean War.
South Korea is our ally, but many tensions have remained since that war. The leader of North Korea may try to attack
America in order to show his power to the world.
North Korea is a minor threat, but a threat all the same. The latest rumors say that they may have the ability to get a nuclear warhead all the way to the West Coast of the United States. The leadership of that nation is irrational and unpredictable, and needs to be treated as if their rantings and threats are serious.
I think that it is safe to say that North Korea really is not much of a threat to the United States. With that being said, they are a severe threat to South Korea. North Korea has the largest amount of artillery in the world, which could be very bad for our allies.
