Your argument relies on two distinctions that seem dubious to me: civilian versus military, and domestic versus foreign. Why do these things matter? Aren't all sentient beings equal? Shouldn't we apply the golden rule to all other such beings? The moral concerns around using force, whether at home or abroad, trump any political, diplomatic, military, or legal concerns. I suspect that distinctions such as civilian versus military and domestic versus foreign are just ways to ease our conscience about hurting and killing other people far away, who aren't quite real to most of us anyway.
