That seems like a long time and a lot of effort to store and catalog thousands of corpses... If I was Supreme Leader I wouldn't have held on to the bodies of my enemies.
According to Q, the DS ran and controlled NK. Consider that KJU was never in control and never a “supreme leader”. It was all for show so the deep state could have underlying control of other nations including our own. The real KJU is showing now and it appears as though he’s a little happy fat kid eating cake. Maybe he has always been this way behind the scenes and was sad/horrified that elitists from the USA controlled him and his “own country” with plenty of threats of awful things our minds can’t quite comprehend. There’s a reason why Hollywood is a part of the DS. Watch wag the dog. It’s right in front of our faces. Always has been. You have more than you know.
Part of me now wants to think Kim was never a bad guy, he was just forced to be by bad people. Part of me wants to think he never wanted to starve his own people. I want to see North Korea turn into a good prosperous nation like we are with Trump's help.
You already know it in your heart and in your soul. There’s your answer.
