I don't believe in running away from a threat. If someone comes up on you and threatens to beat you then go after your family, then you gots to take care of business. NoKo has been threatening the US with nuclear weaponry and possible attacks on our allies. But, they never had the ability to do so. Until now. The US is in a position to having to protect our allies; South Korea, Tokyo, Manila and other locales. If NoKo launches, then it's the end of a lifetime that we've come to know.
