It's very certain that North Korea is developing nuclear weapons for offensive purposes. They don't need nuclear weapons to defend their own country.
I don't think the current regime of South Korea will deal actively with the issue of North Korean defectors.
All of North Korea is a jail.
No doubt it was better to have become president than not.
To Koreans on the other side, we care about your freedom.
In my day, the president ruled with authority before the law, but now all that is lost.
