There is a more practical reason for not boosting the egos of North Korea's leaders and that is that every agreement they have signed on to they have broken. They are even better than Donald Trump than lying. Trump achieved nothing but vague promises in his meeting with Kim, but the the latter got everything he wanted including a promise that the US would end the war games with South Korea. What did the US get? Essentially nothing so far.
Well, Trump got his photo op. Image and world wide attention on that meetup.......would be priority for him. It goes into his brag book of self congratulations.
But tat is ALL he really got........as that so called statement" is a series of words without substance.......
And it is NOT as if NK did not WANT a meetup with him for their own propaganda motives Again.....Tramp gave the what they anted. the question is how will they go about getting more items on their wish list.
(again.......no problem dealing with a leader who has a despicable record of human rights abuses. Not the slightest concern for trump
