Is the threat of danger of world nuclear war can be overcome, only with "appeal" that all parties concerned can refrain?
North Korea's missile test is certain to reach all parts of the US. And China is vigorously shaping world-class military forces, so they can defeat all enemies, and they will remain loyal to the Chinese government. The US, Japan and South Korea jointly prepare B-1B bombers and Japanese and South Korean fighter jets, so that if desired they are ready to respond quickly, shutting down with tremendous power, at the right time.
