I think the poster wasn't talking of the US government but of knowing which government a domain is related to by just looking at it. ".gov" is not clear while ".gov.uk" is clear due to the ccTLD.

I would say no. What makes it clear to you?
I won't go so far as to say that the internet is an American invention but it was certainly primarily American in origin. .gov has been managed by the US government since the beginning.
Not the OP, but also American. For me it's clear because I've never seen a US government site on a non-.gov domain (though apparently some obscure ones exist as this submission points out), nor have I ever seen a non-US-government site on .gov.
The submission includes over 400 domains for the federal only list. That is more than "some obscure ones"
> nor have I ever seen a non-US-government site on .gov
How often are you going to non-US-government government sites? Being an American I could imagine you hardly if ever interact with any other government sites so maybe that could be attributed to selection bias.
The number has nothing to do with how obscure they are.

I have interacted with them many times. (1) to fill out various Covid-related entry forms when those were widely required, (2) to apply for visas, (3) purely out of curiosity (e.g. I’m sometimes curious what travel warnings/advisories other countries’ foreign ministries put out and how they compare with our own).
The us also has .mil locked up for mostly purposes.
Maybe this is my latent American nationalism showing, but isn't .gov "clearly affiliated to and managed by" the US government?
I think this bit was added as an edit or maybe I just missed it:
> an inherently international .gov domain
.gov is not inherently international for all the reasons in this subthread (and probably others as well)
