The word "War" using it in the chimps fighting scenario does give it a more unique perspective amongst other animals and adding to this view that they also stand upright on two legs and throw things more or less like humans.
ya.. it's called Anthropomorphizing.
I just last night watched a documentary on the Discovery channel called, "The last Lions". It was about two separate prides of Lions in Africa, and their battles with eachother over territory around the Buffalo resources. They were separated by a narrow river, that they would occasionally cross to start trouble with the other pack... like attempting to kill the other groups cubs, or pushing their territory back.
Lions, "at war".
What about ants? OBVIOUSLY they wage war with each other.. .some varieties are actually called ARMY Ants.
The false equivalences are endless!
