Forgive my naivety, being a civvie, but why can't we (or the Americans, or even the Russians if they want to) use a covert special forces team to assassinate the North Korean leader? Or use satellites, spies, etc to pinpoint his location and take him out with a well aimed precision strike?
Or am I in the realms of fantasy there? But if I am, why? Surely with our (the 'West') resources and technology, it must be possible to do something like that, especially as he doesn't seem to hide himself in caves or underground like terrorist leaders.
