We will have to wait and see what comes next..this was only the initial meeting with more to follow.
My suspicions are that this entire deal was crafty marketing and illusion for public consumption by BOTH egomaniacs representing their nations.
Both guys get to bask in the illusion of legitimacy, with only North Korea benefitting the most from the photo-ops, while Trump does what he does best: craft reality TV and marketing his image.
Those are my suspicions about this entire "event". When and if Lil' Kim allows UN inspectors into his country to verify that he has indeed de-nuclearized, will be the only evidence that Trump accomplished what he is selling and marketing.
