Kim Jong Un can’t risk having no nuclear capabilities. The CIA/has actors have barely been removed. They are barely free from the extortion and horrors of the old masters.
If the crazy, no borders, impeach!, socialist bent, baby murdering, endless war mongering, democrats manage to steal another POTUS seat - then North Korea is facing the need to defend itself against an insane warmongering America.
If America falls so falls the world.
Did Trump reveal that NK had a hidden test facility, that was missing from the agreement?
Is that why he walked?
