You're talking about the U.S. invasion of Iraq, right? Where the Shock & Awe campaign killed ... between 0 and 6600 civilians [0]? Where 188k+ have died in the 19 years since the Neocons invaded [1]?
This is whataboutism. Obviously the war in Iraq was a terrible mistake and tragedy, but that doesn't give anyone carte blanche to do equally terrible things.
