The United States government perpetrated a unilateral, pre-meditated attack on a sovereign country that had committed no greater contemporary crime then effectively mouthing off and not being in compliance with their truce. Otherwise, Hussein was nothing more than a two-bit dictator or a second world country. The US government spent between $2 and $6T to wage this war and occupation (and the occupation of Afghanistan) all to get rid of this political peon. Now there is value for you....

Sorry, but the attack of Iraq is among the dumbest things our government has ever done. I'm sure glad you are sleeping well at night. $2-6T to remove a two-bit dictator? Now there is value. Let's make this personal. Do you know your personal taxbill for this? Try $40,000 ($6T / 150M taxpayers).
If you wanted to sleep well at night, you should have simply bought your self a Sleep Number bed and banked the $39,000.
