My guess is that it's alphabetical order. If you manage to get Vatican, or even Venezuela, there's not much space for countries to come earlier. If you forget Vietnam, you've still got a lot of a lot of potential space for other names.
Vanuatu is one of those countries so unknown that people make a point of remembering it. Vietnam is one of those "obvious" countries so less people make a conscious effort to remember it.
Exactly... this type of quiz on this type of site is taken much more by people who are into trivia, not just random people. And people who are into trivia remember tiny countries like Vanuatu, Tuvalu, Palau, or Nauru primarily because they're useful as answers on quizzes, as opposed to any major world events having occurred there.
"When the war ended in 1945, the Americans withdrew their personnel from Vanuatu with as much haste as they did when they first arrived, leaving stockpiles of equipment behind. Planes, bulldozers and trucks were dumped under an initiative known as Operation Roll-Up and the islands of Vanuatu became a dumping spot, both on land and sea. A dive below reveals bulldozers, trucks and aeroplanes as the reclaimed home of tropical fish and colourful coral that have transformed these forgotten wartime relics into artificial reefs, making it an excellent diving location."
I played a flags of the world board game and they called it Vatican State with Vatican city being a capital of it. Has it changed or something because it also includes Swaziland instead of Eswatini.
Interesting that "Vanuatu" and "Vietnam" are tied for lowest percentage of guess. I mean, I went for Vanuatu and struggled to pluck Vietnam out of my head, even though it's a more familiar culture to me than the other.
Vietnam just can't compete.
