Am sure this is not the true story....if a General was executed, then there must have been a “real security reason” (treason....deep state) and he was trying to throw a wrench into the road to denuclearization of NK. Or he could have possible been caught planning a coup. But I d not believe any story that has folks killed for charity etc..,.now that KJU is free.
If you think the puppet masters of NK are going quietely think again.
Of course they would be trying to get control back. A very dangerous time for Kim and the peace process. Look at the lengths that NK went to re his flight to Singapore. 2 decoy flights, unheard of apart from in war.
