The latest CIA reports say that we DID find WMD in the form of chemical and biological weapons and/or programs to produce weapons after invading Iraq (just not "stockpiles" of WMD). The MSM will not report accurately on this, but there were other reasons for removing the regime in Iraq. Here's a partial list (please add more if you know of others)
1. State of war existing since the first gulf war
-Numerous violations of ceasefire agreements by attacking Kurds and Shiites
-Numerous violations of ceasefire agreements by firing on US and UK aircraft
-Attempted assassination of a former US president
-Conspiring to cheat the UN sanctions oil for food program
-Violation of numerous UN disarmament resolutions, possession of prohibited conventional weapons
-Failure to account for coalition MIA/POW
2. Capabilities to produce chemical, biological, and nuclear weapons were maintained in spite of UN inspections, ready to restart development as soon as sanctions and inspections were lifted
3. Known nuclear material (LEU) stockpiles
4. Known state sponsorship of terrorism; numerous terrorist organizations who have attacked the United States and/or our allies
-Iraq has been on the list of known terrorist supporting states since the list was first published
-Abu Nidal
-Al Quaeda training camps (at least one), key Al Quaeda operatives in Iraq
-Support for Hammas suicide bombers in Israel
According to John Kerry, your must choose only one reason for invading Iraq. Having more than one disqualifies the whole war makes you a liar.
