North Korea was already leveled wall to wall with air strikes. That's why they're behaving this way, because the USA already demonstrated that they were willing and able to bomb the entire country until there were "no more targets" left to bomb and the Korean people needed to start living in caves to avoid the mass dropping of napalm.

gee i wonder why they built nuclear weapons for deterrence, just look at how peaceful and understanding the liberals are!

Maybe Kim is hitting fuck it territory
