First off no. That was not the core question. You said:
Take, for example, the claim that North Koreans are permitted to leave the country.
The answer is yes they are permitted. Despite how you attempt to twist what the law says and what we were talking about to dodge this fact.
Secondly obviously you can't move to a hostile power during wartime that's called defecting. No country on Earth currently or has ever allowed that.
Are you trolling?
