It's not aimed at a domestic audience, and until recently this was enforced by law. VOA is also explicitly propaganda, at least under Bernays's more neutral definition of propaganda: it is intended to influence foreign populations to view the US in a favorable light, using what VOA considers to be the most accurate point of view.

Propaganda isn't just Soviet posters describing the abundant harvest. Any widely broadcast messages with an explicit goal to influence populations, even if the messages are accurate, is propaganda.

The recasting of propaganda as "evil lies" (or "fake news") has poisoned the well when it comes to discussion of accurate propaganda, which still exists and is in use every day.
