It's gives North Korea a nice big propaganda win and lets Kim go back to Pyongyang crowing about how he got the U.S. to fold on an issue they've resisted for decades.
So
what? I keep hearing about a "propaganda win", but what is the actual,
tangible value to NK (or cost to us) of that "propaganda win"? What does it actually get them?
This is my biggest issue with foreign policy pundits and politicians. They put more emphasis on "optics" than they do on real-world, tangible actions. It's like a politician who bases every single decision or statement on the short-term effect on polls. The value of such "wins" is fleeting at best. Nobody will care about that "propaganda win" in six months. It will be completely irrelevant.
And what happens if in 90 days, Trump is calling him a big fat liar who broke his promises, and who presides over a bankrupt, starving country? What does that do to any "propaganda win" the NK's may have gotten from this meeting?
People are far too concerned about how things "look", than what actually
happens.
