North Korea always says it will take unspecified “resolute action” or some such nonsense every time the U.S. does something NK does not like, such as the annual training exercise with South Korea that have been conducted since the Korean War truce in 1953, which NK claims is preparation for an invasion of NK.  No invasion or any other hostile action is ever taken against NK, but the generals end up with a chest full of medals for the “resolute action” they took to stop the U.S. aggression.  It is really laughable.
