No doubt China & NK is playing Trump and it is a gamble; our State Department and our military know it. NK is only a puppet and China is the one who pulls the strings. China probably think that we don't have any resolve to face NK militarily. According to Reuters and other Asian news reports, it is not that we don't have the capability but the major concern is Seoul, South Korea's capital. It is only an hour away from the border and the most populated city in South Korea. We can certainly take out NK militarily; but we may not be able to effectively protect Seoul and its people, it is too close to the border. Collateral damage will be too big.
