War crimes as a concept was invented by the current US hegemony to punish others, not to be bound by.

I think about it this way: would I have had any problem with the allies bombing Nazi rallies, even though they were mostly civilians? My answer is absolutely not. I feel the same way when I see pro-Islamic regime or pro-Hezbollah rallies. In fact, I think the limited repercussions for these extremist civilians - and their very tangible support for the regimes - is what keeps these movements alive and powerful. Cost to civilizations - military and civilian alike - is what ends wars.
