Data mostly from Wikipedia. No warranty. For example, Slovak is arguably not an official language in the Czech Republic, just mentioned as “mutually intelligible” in certain laws but I followed Wikipedia and included it. Languages are grouped by the acronyms and sorted by their 2-letter codes. Those are based on their Wikipedia URL or my guess (sucks to be you, Montenegrin speakers, should have made your own Wikipedia). Countless Sámi languages are represented by North Sámi, the only one with a NATO Wikipedia article.
Changelog from v1 I originally posted on Reddit: Hungarian ÉASS → ÉASzSz (the “sz” stays together in acronyms because unlike most letter pairs it makes a single special sound).
Look, any organization that has a name and acronym needs it in one language, and it’s obviously going to be English in the world of 20th/21st century North-Western diplomacy. Any more are a burden.

Wouldn’t be so sure about the entire 21st century. There are some major efforts by the English speaking parts of the world in recent years to ruin that for themselves.
