It's War And It Isn't Pretty
But If you had a clue about the hoistory of war or were honest about it you would know we are harming a far smaller portion of civilians than in previous wars. Your argument boils down to there is no excuse for war while avoiding any attempt to face the fact that no war also has ugly consequences. The very fact that the situation that lead to those civilian deaths was instigated by Saddam to cause such horrible mistakes should clue you in on why letting this man continue to rule is wrong.
