Gotta suck up to the Boss on this one.

In the entire Western Hemisphere, there seems to be only one nation that includes the term "America" in it's official and commonly used name. Hence politically-historically the use of Americans for citizens of the USA has been universally accepted. If the discussion is geographical the terms normally used would be North/South America or The Americas.

I doubt if anyone used to reading academic material would become confused with these designations.

Normally the Russian/Soviet label seems to be used primarily to avoid redundancy and allow the writing to flow. If the primary topic is anything but demographics, the terms have become acceptable and understandable.
