I think worrying about the impact in civilians who had no part in a crimes by their fellow countrymen but are being punished by the bluntness of a response is perfectly reasonable. In fact, I find the opposite (an utter lack of concern for it) to be unreasonable.

That’s true whether the blunt response is economic sanctions or widespread bombing.

Those actions might still be the best available response overall, but that conclusion should be reached after considering the effects on innocent civilians, not after ignoring them.
