In fact, the US, UK, and every other culturally Anglo country could sink into the ocean tomorrow and I suspect English would still be a dominant international language for the foreseeable future.

You seem to be answering some other, unrelated question.
I kinda doubt that, given its writing system.
I don't speak or read Chinese, but my understanding is there are a lot of homophones (and a culture of homophonic puns) that would make that undesirable (e.g. https://en.wikipedia.org/wiki/Homophonic_puns_in_Standard_Ch...).
But wouldn't that lose something? My understanding is a lot of the puns specifically rely on the characters to force a different reading than the context would imply (or to evade censorship by having many ways to write the same sounds).
For example, a shockingly small amount of John Calvin's works are translated into English. Regardless of what a person thinks of his theology, his influence on the rise of democracy in post-Reformation Europe and the Americas is staggering.
You can find "the essential works of John Calvin" (51 volumes, in English) here: https://www.logos.com/product/145428/the-essential-works-of-...
All of John Calvin's commentaries, letters and 'The Institutes' here (109 volumes, in English): https://www.logos.com/product/5170/calvin-500-collection
Calvin's tracts and treatises (8 volumes, in English) here: https://www.logos.com/product/5165/tracts-and-treatises-of-j...
I'm curious as to what you think hasn't been translated into English.
There was a Latin collection that contained some of these works called the Corpus Reformatorum published in the 1800s.
