*grin* Depends on what you call an actual argument. A spoken one, no. But if you go with argument being a dispute, pretty much all wars, by definition, are just that.

"arguere" - to make clear.

Yeah, I'd say war clears up who owns what parcel of land or gets to set up the rules all right. Well, at least from the pov of the folks waging it. ;-)
