Bombing civilian infrastructure is a war crime because the end state is the same as bombing civilians. Killing power shuts down hospitals and emergency responders (generators run out eventually) and desalination plants. The military is largely unphased, they’re the first ones to get gas for generators.
Also, this is carpet bombing. Carpet bombing is the targeting of civilian infrastructure with effectively willful ignorance of the collateral damage.
We started a war knowing the only way to win was either boots on the ground or war-criming our adversary into submission. We don’t get to pretend our hands are tied and we have to send out the bombers. We don’t have to do this because Iraq forces us to, we have to do this because we elected a man who can barely read Post It notes and ignored half a century of military intelligence. We are at fault for every dollar of damage caused to infrastructure and every life lost.
