If the U.S sent every thing we have along with every troop (including those deployed in iraq/afghanistan) NK would be squashed in 3 days or less.

Though it is true they have alot of fighters, soldiers, etc.. They just would not be a match against a full blown assult by America.

To be honest, if it werent for all of our treaties and conventions, we could just napalm and gas the entire country in a few days and then move in to clean up whats left.
