Its war for crying out loud. A certain (small) percentage of the bombs are going to land on women, children, and old people. When is that ever OK?
Your "ideological purity" is far outweighed by real blood. If I make the judgement call taking into account real lives, your ideology doesn't mean squat.
So some Iraqis lied to get us to drop bombs in the vicinity of their relatives because they considered our bombs less of at threat than the madman they were meant for.
Let me try to be succinct: Unless you can demonstrate that 1) Saddam was not threat, 2) Saddam was not financing terrorists, 3) Saddam was not a complete butcher, I DON'T CARE.
There was an elephant in the room and you are concerned with the dust mites.
