Iran is a bucket list country for me. The politics are a disaster, obviously, but it's an amazing, deep culture. The government of Iran is a disaster, but it's a real, functioning country, in ways North Korea isn't.
Ironically, Iran is probably much more dangerous than North Korea is (not least because you apparently basically can't do anything in North Korea), at least for an American. But like, if you want Korean culture, fly to Seoul and rent a car. I don't know how you get Iran's culture without actually going there.
