Ah! We've moved into the "formal investigation" stage concerning the killing of hundreds of Mosul civilians by the US military. That's a formal investigation conducted by very people that committed the killings, of course. So now the days of issuing doubts, denials, and deflections have passed. Sort of. In admitting they dropped the bombs that killed all the civilians, the US military also issues many excuses about how it's just so darn hard to drop thousands of bombs without all the collateral damage.

Yes, it's a fact that bombs and artillery used in civilian areas will indiscriminately kill civilians and combatants alike. And that's why there's laws in the Geneva Conventions that PROHIBIT the use of such weapons in those circumstances.

Even though the USA accused the Russians of committing war crimes by attacking east Aleppo with heavy weapons, the USA is doing the same thing in its assault on Mosul. Sauce for the goose...
