Although we do not target civilians, an entity that decides to go to war must consider that in all major wars since WWI, more civilians have been killed than combatants. Therefore, there is a moral imperative that War should be the very last resort. There was no indication that any other alternative was attempted first (see my posts above for some of the possibilities).... we don't target civilians, thats what our enemy does.
I suggest that the reason for that is, the I.Q. of the sitting president is not sufficient to be aware of the historical facts of war: It will not be over by Christmas., The unexpected can and will happen., More Civilians will be killed than soldiers. Anyone who has a higher I.Q. than the president is aware of his limitations.
