Nothing wrong with Croatia, it's actually a beautiful European country. Why not keep your unattractive xenophobia to yourself?
You're right the country itself is beautiful and I would imagine the people, aside from Lloyd Evans, are decent. Well there was that one time the region ignited a World War, but Croatians would argue the Serbians did that. Same people, just a few mountains away and they were the same country not all that long ago. However you can still be a "shithole country" if you have the crime of insult in your law. My guess is Wing Commander was basically reflecting a similar statement Cappytan made in this video.
