“I don?t see the motive for the Norks to start something big, or the value to them.”
You’re thinking rationally. The Nork leadership isn’t rational. They believe that they are invincible. They are buying into their own propaganda, maybe because anyone who disagrees is shot...
I think you are off tangent on the rationality part. The North Korean regime has survived this long because it is rational. It has perfected the art of brinkmanship by ratcheting tensions and then stepping back after gaining concessions. If they truly thought they were invincible, they would have attempted an invasion long ago.
