DPRK is being vilified because it was full communist and Americans can't access resources of DPRK .
China is being vilified because it has grown too much and America fears that it will loose it's influence when it will become number 1 economy. When they loose their hegemony /superpower status and then world will be transformed into murli polar world and then usa won't be able to do whatever they want like fabricating lies of WMD to just loot resources of middle eastern countries since last two decades.
Since nobody is above or as equal as powerful as USA so international laws doesn't apply on it. This fear of loosing superpower status is haunting them all the time , but it can't do much and only relies on propaganda, but in reality after a decade these propaganda won't work because by that time china would have surpassed them in economy, as well as they would loose loose in trade war by decoupling with china and inflation will eat their middle classes which will stagnant domestic consumption since USA relies heavily on consumption economy then you will see huge devaluation of USD dollar . I don't see any good future of USA.
