No, certainly the USA (https://en.m.wikipedia.org/wiki/United_States). The author is most likely Austrian or German and it is quite common to say "Amerika" for the USA there.
i was referring to this btw: America" (which btw is a continent, not a country)
A notable exception, and where much of the disagreement comes from is Spanish. I generally try to follow the convention of the language I'm speaking.
