What "policy" could possibly be revealed in the last gurglings of Bashar al Assad's gas attack victims or his barbecuing of civilians in his homemade napalm baste?

War, in his book, is about saying to your enemy: "Do as I say or I will smash your brains out and murder your children".
This has been the conversation of all wars until the post WWII evolution of international law governing conflicts. These now demanded that war needs to be fought according to rules - like some kind of sport.
