The punchline goes a bit further than just imprisonment, see the Stanford Prison Experiment

How could our beloved leader engage in war crimes if we do not see war as a crime?

Checkmate, Westerners.

Our citizens pay taxes out of pure love and devotion to our Dear Leader. We don't have room for your silly Western moralities.

This is fake Western news.

The lights illuminating the statues of our Dear Leader shine 24 hours a day.

People view North Korea with contempt? Who would do such a thing?

No, seriously, we'd love to know so we can send them to a reeducation camp change their mind.

Trains do not derail in North Korea. It is forbidden.

Those are photoshopped images from untrustworthy western media; do not trust them. Homes in North Korea shine as bright as our love for our esteemed leader.

Please stop sharing lies.

The highly esteemed Kim family does not require food, so your point is entirely redundant.

1800s? Public executions are a treasured pastime in my country.

There is only one size in Best Korea. It's derived from our Dear Leader's own measurements and called "Medium".

There will be no questions.
