Steady escalation.

One step at a time, hoping war is not necessary.

But it is.

Norklandia will never voluntarily give up it’s nukes, nor missile development.

Never.

This measure can be augmented with covert sabotage of their key installations. Especially those close to NK-China border. They could include more than military installations. Such as their oil refineries. They do have oil refineries close to their border. Not sure they also have one inland. They can smuggle in oil all they want, but without oil refineries they have little use. Who knows? Maybe something like this is already in progress.
