Trust me...Lil Kimmy is looking for an offramp, but he didn't think far enough ahead to build one on this road to war. He will probably launch one or two test missles. One of them will probably go over Japan. Japan will probably shoot it down as a slap to his face. He doesn't have nukes he can launch, so no one is worried about that. As far as his tunnels go, if it gets that far, we currently have the appropriate aircraft and munitions in the theater to destroy most of the tunnels...for the most part they have been mapped.
