(a) it was related to the 9/11 attack on the World Trade Center...then you are buying into lies and twisted logic.
(b) Saddam Hussein harbored terrorists,
(c) Saddam Hussein had weapons of mass destruction,
(d) Saddam Hussein was a valid national security threat to the United States,
(e) Iraqi citizens would welcome Americans as liberators,
When you grapple honestly with each of the above lies, half-truths, misleading information, bad intelligence (call it whatever you need to call it), you will see that America has no business or right to be in Iraq.
All of the "evidence" and "rationale" for opening up a war in Iraq have collapsed like a house of cards. Still, our President doggedly deploys more troops to Iraq for a war for which he declared victory a year ago.
Iraq did not provoke war. An American President declared he had the right to attack any nation he deemed a threat on "preemptive" grounds. He did so. Those "preemptive" grounds did not and do not exist.
If our nation is a nation that values the power of reason over the sheer use of whimsical and personal will, it follows that American citizens have every right and responsibility to insist that the American President use his "political capital" to extract his nation's young men and costly resources from a quagmire into which he blindly charged us.
