North Korea has nuclear weapons. They have ICBMs that can hit west coast of US but few enough that maybe could be intercepted. They also have shorter range missiles that threaten South Korea and Japan.

North Korea has few enough nukes that first strike to take them out is possible. But would likely require using nukes. China, and much of the world, would not be happy. Acceptable if war has broken out, not to start a war.
