My take is it was meant to show the NKs a disgusting representation of America.
We are used to his looks. I imagine the NKs think he is some kind of monster.
I was thinking about this the other day. When he met with high ranking NK officials did he remove all his piercings and look somewhat normal?
What did these highly disciplined brainwashed people think of him?
Wait til we send Pee Wee Herman over to talk sense into them.
