Your country's law would deport them or jail them if they said anything positive about NK, right?

And a question on SK history from the last half century that you probably learnt from:
https://en.wikipedia.org/wiki/United_States_Army_Military_Government_in_Korea
https://en.wikipedia.org/wiki/Autumn_Uprising_of_1946
https://en.wikipedia.org/wiki/Jeju_uprising
https://en.wikipedia.org/wiki/Gwangju_Uprising
So are the tricks of the last half century yours or theirs, considering how many people don't know that SK was a dictatorship for a long time?
How do you view these things?
And the sanctions and the war drills that US-SK does together?
