Possibly just another ploy in the giant bag of tricks the kid dictator has up his sleeve.
If these demolitions were on the up-and-up, they should have had nuclear scientist on site to verify the content of what was being destroyed.
As far as I am concerned, the kid dictator made a 360 to willingly and uncharacteristically based on his past radical and unstable reputation.
The only thing that PDT can do is to give him a little more rope to see if he might hang himself.
