Deliberately targeting civilians during wartime is always a depraved, immoral act.
Not always. Many civilians play a part in war, and are thus targets.
Unless they're high-ranking public officials directly responsible for war-time strategy or work in a munitions factory, there's no justification for deliberately targeting civilians.
Civilians will always play an indirect role in supporting the war effort through their taxes or their participation in economic life but that's hardly a justification for deliberately targeting them. If necessary, I will post a long essay about the moral foundations of the rule of discrimination but this really shouldn't be necessary: civilians, and by this I mean "non-combatants" do not pose a direct threat to anyone.
Note: I voted "no" in this poll. Terror bombings were depraved, immoral, despicable but they could be excused under the circumstances, which were quite unprecedented. Regardless, violating discriminatory targeting requirements
always merits a court case or a trial.
