Not just a nation - any group.
I heard somewhere that all modern wars must now start by the leaders of the belligerent countries comparing each other to Hitler. The title here sounds about as well reasoned.
It's funny you say that. Putin started this war by pushing the ludicrous claim that Ukraine is now run by Nazis.
The is quite favorable claim by him. More correct title would be "The War in Ukraine is Genocidal War", but this title is not wrong either.
