"the US also bombs civilians to take out military targets"
Not wrong though.
IRC the initial shock and awe coordinated 'surgical' bombing at the beginning of the 2003 Iraq war cost the lives of up to 8000 Iraqi civilians. I remember watching it at the time, and American media were really gushing about that whole thing. Going on about how precise it all was. Apparently if you dress it all up in a bit of newspeak (collateral damage, precision bombing, surgical strike, ...) you can convince most people that the pressure wave from a large bomb stops at the window of a building.
Maybe international law is too lax. Maybe the US is too powerful to face consequences for anything but the most egregious examples, but then again it's not as if the world (including the middle-east) gives much of a shit when Assad barrel bombs yet another a hospital. And no one gives a shit about the thousands who died in Sudan this year, because they're black, so they apparently don't count.
In a deeply cynical way, it makes sense that the IDF and Israel think it's unfair. Why should they get so much flack for war crimes, when others get away with it consequence free? China got to demolish ten thousand or more mosques, Russia got to demolish multiple cities and deliberately murder sheltering children, it's only fair that Israel gets to commit a bit of genocide.
I'm old and tired, and please understand this is an angry and sarcastic comment, but I do wonder what people think war is actually like. Especially urban warfare. Because given history, it seems to me that this is what it's always like. Thousands of dead civilians, razed buildings, and flimsy excuses and technicalities which allow countries to get away with (not so) accidentally murdering thousands. The world's biggest and least funny joke.
