Before the 'selective' targeting there were fewer civilian deaths... Killing a house full of the wrong people is a crime, but perhaps not as great a crime as obliterating an entire village. As soon as you have asymmettric warfare where the combatants are mixed in with and indistinguishable from the civilian population instead of in nice military camps and uniforms this is inevitable. The interesting question is who is responsible, and there are no easy answers. In the Korean War my father's contemporaries didn't like shooting up ox carts, but when one in five is full of ammunition and explodes and mixed in with the peasants going to market are peasants carrying supplies for the troops - where does the responsibility lie?
