trump's un speech, threatening north korea with total annihilation could possibly be strategic. so say the us was really hinting that china had better remove the nk regime (cf entry a couple down). if china really was contemplating a nuclear or overwhelming sudden conventional destruction by the us right on their border, i think they'd act one way or another. and again, i'm suspecting that they've already infiltrated to some extent, and might be better than the us in imposing sudden cyber-destruction. look no other military procedure is even remotely plausible, including that american attack.
