You’re being intentionally obtuse here, we’ve already established that the context is sufficient to make non-USD assumptions absurd and you’re attempting to further the argument by restating points that have already been stated and refuted

Fine, change Ukrainian to Australian and my point still stands.

In my personal experience, Australian journalists are generally pretty careful to distinguish Australian dollars from US dollars from other dollars when reporting on international stories, at least in the article body (headlines less so, but the journalist normally has no say in the headline). Of course, for domestic news, it goes without saying that “dollars” means the local currency

I dunno

I'm Canadian, I live in Canada, I earn CAD, My whole economic life is in a context of non-US dollars

But if I see $value in an unknown context online I assume it's USD

I think it would be really goofy to assume otherwise
