A study conducted by Visit Sweden in the US found that half of the respondents were not sure if there was a difference between the two nations.
And while they’re at it, they might make up a quick brochure on Switzerland vs Swaziland. (Swaziland was renamed Eswatini a few years ago, probably to avoid the disappointment of Americans who arrived there to ski the Alps. I’m willing to bet that, rounded to the nearest percent, zero percent of Americans know that Eswatini is a country. If you give us a multiple choice, we would probably identify Eswatini as an Italian cocktail. “Vodka Eswatini. Shaken, not stirred.”)
When I was in the Netherlands, the locals there told me that visiting Americans were convinced the locals were Danish, not Dutch. Ah, we Americans, always ambassadors of ignorance. You have to give us different first letters or the words look the same. Most of us probably can’t even tell Poland from Peru.
Also, Czechia and Chechnya might at least tack up a few flyers for us.
