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).

I count 5 languages and 8 countries for OTAN and 3 languages and 5 countries for NATO, so if anyone is being entitled and not respecting the plurality is the anglophones.
Never knew this, thanks
