Very Good comments - I think you are absolutely right - NK negotiations take time (been about 20 years now) and I have faith in President Trump. Who knows what the “letter” said, it’s all speculation by the Media. I think like you that Trump has something going on that will be revealed when necessary. Take for example trade deal with Mexico. All the media types were trashing the negotiations and saying it was going to fail. Then at the right moment, TRUMP announces the “art of the deal”. The heck with the Media and their pundits. NK will come around as soon as China “sees the light” and stops helping them - I figure the next trade talks with China will start the ball rolling.
Like I told the other guy - quitters never seem to accomplish much....Trump is no quitter.
