Ever heard the phrase "The Laws of War?"
Uhh . . . what, war has laws? You're not allowed by the Geneva Compunction to shoot someone in the back of the head? IT has to be in the SIDE of the head?
How can war have LAWS? What, no civilians, no collateral damage?
What is it about the word WAR that people don't understand? War is the explicit act to kill as many of "the enemy," whomever they might conveniently be at the time, as possible, in whatever manner.
