If you were to apply chronological thinking to the Iraq War, which action would you most likely take?

It was Bush administration who claimed that Iraq had Weapon of mass destruction (WMD) and Saddam Hussein would use these weapons to threaten America and Saddam also had linked with terrorist organization AL-Qaeda which was responsible for the terror attack on 9/11.

well, the reason behind the invasion of Iraq by the Bush administration was blundered and failure, US and coalition forces did not find any WMD in Iraq.

The original goals of the war appeared to have been:

Depose Saddam Hussein regime. Create new democratic Iraq. Take the first step to transforming middle east into a new democratic region.

If I take action against Iraq, I would first investigate the facts of presence of WMD in Iraq and then take the non-violence methods to dis-arm Iraq's WMD because War create more problems then solution.
