You state: "the final number casualties aren't the point". Oh?

You state: "the tactics are what matters". Oh?

You state: "it's clear that US/Iraqi forces are no less destructive of civilians and their property than were the Russians and Syrians". Then, it's also clear that Russian/Syrian forces are no less destructive of civilians and their property than were the Americans and Iraqis.

So, we agree, then?

Everyone is swimming in blood, none are innocent, none are more or less guilty, everyone has failed, and no one--no one at all--will ever be brought to justice for their war crimes.

What a delightful war. Everyone blames everyone else with perfect justification, nothing changes, and no one ever goes to jail.

Not even Assad.
