They share a goal of wanting US-ROK wargames to cease as well as the US to depart the peninsula, a nuclear armed DPRK at least provides bargaining chips toward achieving that goal. The continuance of the status quo or any escalation of tension short of war only increases China's role as chief mediator and lynch pin for any peaceful solution for which untold concessions will be given. I don't see what liability DPRK actually provides to China short of getting into a real war.
Their military is increasingly outdated but this is mitigated largely by terrain. Unlike the Iraqis fighting in the desert the USAF can't bomb them to impotence, it would take a lot of close fighting at ranges dictated by terrain as well which negate the range advantage of many of our weapons systems. It would be a meatgrinder of a war at the start and would have massive ROK causalities followed by relatively heavy (by our standard) US causalities as our forces piecemeal into theater due to the lack of large nearby formations.
I will agree that this is the last window for the US to deal with it without nuclear missiles raining down on the US and territories (my state of Hawaii is supposedly in range as well). The best window was of course during the mid-90s but Clinton would never have started a war with the DPRK even for the legitimate humanitarian reasons that could have been created and the post-Tiananmen PRC would never have stood by and watched their ally destroyed.
If military force is the only option left then the time is very close indeed. The situation is like a light version of the cuban missile crisis (not quite to M.A.D. level yet). I don't have confidence however that our president could do the diplomatic work needed to put us in the right light in view of Russia, PRC, ROK, and Japan if were to embark on military strikes on nuclear and ballistic missile facilities. I hope that McMaster and Mattis force the type of foresight and planning required but it doesn't look like their advice is heeded by the POTUS very much.
I fear greatly that we might blunder our way into a war instead of actually preparing for one and using that state of preparedness to negotiate from a position of strength (the US Army is not prepared for war in Korea right now). Remember that Saddam thought that George W. was just playing hardball and wouldn't invade without explicit okay from the UNSC. Having more US forces in Korea would also force China to actually take us seriously. The danger that they think we're bluffing is very real given that in the past we've been the restraining influence to ROK's wanted revenge for all sorts of outright acts of war by the north.
