Your statement about North Korea strikes me as a very discriminatory, as it implies your judgement about NK is somehow objective, and it's political system is a condition justifying them being denied equal treatment in various situations.
It is perfectly reasonable to discriminate against political systems that you disagree with. It's pretty much the basis of international diplomacy, such as it is: a system of bargaining and coercion that usually prevents outright war.
Caring about political systems is just spin used as an excuse.
Indeed, the US at the same time went hard after Japan whose political system (even though in practice is barely it at all democratic) it created, but courted the Chinese one-party state.
The rest is just rhetoric.
