Sooooooo . . . we don't want to spread our American principles and values to NK?????

See, that's the problem, as well as moral and intellectual weakness, as well as incongruity, as well as ignorance, as well as a host of other problems with Pocho's initial proposition. 

Free speech is principal and aspiration first.  Fundamental to the concept of free speech is the idea that speech one disagrees with is the speech that should be most protected.

But, speech that threatens or incites violence, I think in under American law, is not, and I think SHOULD NOT be protected.  The White Supremacist speech both threatens and incites violence.  So does Jong Un's.  Americans who are the targeted, potential victims of what that kind of speech threatens or advocates MUST be protected, and that sort of speech punished or dealt with through wise deterrance.  

You think White Supremacist speech is ok in America?  Then you think Jong Un's speech threatening Americans is also ok.
