Its difficult to name a war in which the American miltary has killed, even close to the number of civilians as its opposition. WW2 germany? Japan (remember china). the USSR? the PRC today. North Viet Government? North Korean? Afganhstan? (yeah the Tailban killed more civilians) All of these war/conflicts the US kills far less civilians. Is that ideal no civilian dies but the conduct of the opposition in this war maximizes civilian causulty often but no one says anything about those and people led with the Armed Service is just all murders.
You are simplifying the horror of War to some ideal where people don't have to die. It just doesn't exist and just comes across as Russian anti-liberal rhetoric. The structure of our miltary and its actions are not poor or unprofessional espeically when you look at literally any other peer nation.
