the explanation is a lot simpler - and: I found your post 1 month late:
everyone in the world realises that the Trump is unstable, not to be trusted, possibly an instrument of the 'deep state' conservative side - or all of those things, buthe is a man given to sudden insights, however, immature, uses words like an uneducated teenager and is not to be trusted as to his future actions. Even if you do not speaka da English, it is obvious that man is uneducated, unreliable and given to spur-of-the-moment 'decisions' so:
Many 'leaders' have sassed that out much sooner than the majority of his supporters and have decided, decisions can be made without him, over his head and maybe if credit is given to him, one has patted 'the beast' into a state of narcisisstic satisfaction - let him have his say, give him credit but do as you really want to do anyway.
BTW has North Korea begun dismantling its nuclear program and facilities?
My guess, and it is just as much a guess as your fanciful deep state and CIA theories is:
that both North and South Korea are sick of living in constant fear or preparedness for war - my guess is also that perhaps China whispered a few words of encouragement into Kim's ear, because China is now more powerful and no longer needs a dangerous watch dog at its door.
