Yes, it says “most countries” but the cynic in me can only see this as a kind of cultural imperialism where the US/Anglosphere tradition is given priority over any local one. I don’t even celebrate and I’m still annoyed…
You’re upset because a PR site from an organization run by a branch of the US military is US centric? Get a grip dude. There are plenty of reasons to hate the US, but this really isn’t one of them.
There are ~50k US troops stationed in Germany and ~800k German speakers in the US based a quick search. Maybe it’s for them.
What I’m saying is that if you want a version tailored to your local customs you should talk to whoever runs your air defense system instead of getting mad that NORAD isn’t catering to you.
