Ah, the "so what" in that sentence might have been misunderstood. What I meant by that is that attacking civilians or civilian areas is prohibited in international law, but those prohibitions are generally disregarded both by the leaders violating international laws and most of the other leaders around them - that's the big "so what". It's unethical, it's illegal, it's evil, but leaders of nations will still do it, because they know that most of the other nations' leaders will look the other way. That's what I mean by international law going out the window.
