The phrase "warmonger" doesn't specify anything about the nature of the war, or the reason it was started. It's a very simpleminded "war=bad". If that's how we will be judged, fine.

As soon as you use the phrase "unprovoked" then you start getting into messy details. Are we so sure that the war in Ukraine was not provoked by NATO expansion? Are we so sure that the war in Iran was not provoked by Iran's actions against Israel or against its own people?

The ideologue doesn't like details. They prefer to see the world in black and white.
