Hands down we win this.
It is irrelevant somebody had drawn a red circle before for some reason. This is specifically about usage as national flags. Maybe I can find two red lines next to each other from an older source and then claim this as the mythological birthing point like Japan does. But that's irrelevant. It's about the idea of a nation and a flag representing this nation. We win this battle of ideas.
