The political system (meaning, you're not removing Bill Clinton, Bush Jr, Obama, Hillary, or Trump and the whole thing changes) of the United States is one non-stop monster of war that is so addicted to war and conflict overseas it can never stop. Not on its own power. No addict does. Which evidences they are addicted, they stop when they are deprived of their addictive substance, no more money to buy it, the "bartender" cuts them off, they OD, they go to jail... something other than themselves stops them. Unless they have a radical personality conversion (which is what the 12 Steps are supposed to *help* facilitate).
Trump was elected by many to "drain the swamp" or that is to say to arrest the monsterous war addiction of Americana politicalcana. The "system" as the Southern Italian Camorra (one form of Italian mafia) refer to themselves (calling the Camorra "a system").
North Korea, Russia, Syria, Venezuela... hell if ever deprived of the substance of their addictions elsewhere watch your rear-ends Canada because US troops and war planes will be headed your way.
The United States as ever is assuming a Black Swan does not exist. That hunger for the needle of war in their arm has them tapping their veins and not thinking clearly about the welfare of their family (all the little children in the US running and playing from East Coast to West Coast, the working people etc.). A series of miscalculations might prove deadly for the American war addict and they OD from a bad batch, assuming it was perfectly good and not a Black Swan.
This is less a question of what the little fat man tyrant wants in North Korea. Left to itself the North Korean political system will likely eventually fall--without mass war and the American war industry making $$$$$$$.
So, what America wants, the neocons behind Trump in part running the country, is that they want to make up an addicts lie for their fix, they want inject their drugs in their arms near North Korea with nuclear weapons being based and positioned at China. Because addicts lie to get their fix. And the American system is objectively a war monster unlike any other on planet earth. It's repeatedly the US threatening and making war on other nations.
Trump has become a puppet of the system. He did not "drain the swamp."
