Is the military absolutely certain they / WE are not killing innocent Iraqi people? Is the military, and our government lying to us . . . ADAIN?  Are these more American war crimes which we will justify in the name of "retaliation?"  Is the United States becoming a pariah in the "World Order?"

The UN defines "War Crimes" for the world.  The US Government announces it carefully selected targets in Iraq to bomb in retaliation to Americans being attacked in Iraq,  Can they be sure they did not kill innocent people in a city?  No, they cannot.  Bombs are not that precise as these bombs have a ripple effect for hundreds of meters all around the impact of the bomb.
