To sum: The real definition of genocide makes me ask questions that are deeply uncomfortable so I'm just going to rage instead. Also, we only genocided because Hamas made us genocide, but we didn't actually genocide because Hamas actually blew up all of the stuff. We're not as bad as Hamas so that means we didn't do the genocide thing because I'm just making this up as a go along.
As for the whole "it's just structures!" bit. If you destroy everything that makes modern life possible in a place, you've made it uninhabitable for the natives. Even if you don't kill a single fucking one of them, that's genocide by the legal definition of the word that was created almost specifically to prosecute the Nazis for doing a worse genocide to your people. They didn't put the line at "death camps and wiping out the populace" for a fucking reason, and a good one.
