Based on Kerry's behavior lately with Iran, I cannot help but wonder if Kerry or someone else left over from the Obama disaster, or maybe someone in the Deep State, has been working to make sure the NorKs cancel the meeting.
We know there are people currently in government, and certainly in Obama's old government, who would do anything in the world to torpedo anything Trump tries to do, no matter what it is or how beneficial it may be to America and the World.
