I could be wrong, but wasn't the war about the right to live in the kingdom of Vale? I'd probably have to go read the transcript or go back and watch again, but I think he said that the humans were trying to force the faunus to live in Menagerie, but they wanted to live alongside humans, thus causing a war.
