Let's put it bluntly: If Kim wanted to have ANY chance to save face, he HAD to show. And he DID. He even invited Trump to step across the border into North Korea itself.
Make no mistake. This may have been an "offhand" tweet to invite Kim to the border, but it was typical Art of the Deal coupled with Robert Ringer's
Winning Through Intimidation. Additional bonus: It COMPLETELY caught the Soros Propaganda Division, aka the mainstream media, completely off guard. And a bonus: Seeing the new press secretary MANHANDLE the NoKo security to allow the American Press in to cover the event was absolutely stunning.
If Kim had any idea of waiting out Trump's first term to see if he could get Kamala Harris to give her a sweet Iran-like deal to restart and restock the nukes, he has to rethink this plan.
