Did America shoot itself in the foot with the war in "I-raq"?

Didnt need to go there for any reason whatsoever. No WMD's. 3000+ US soldiers killed for no reason at all, sons and daughters of people with bush telling them a lie. Then hundreds of thousands of iraqis killed which never intended to harm the US in history. All along when in Iraq women could get educated in universities and work freely, people could start businesses and prosper and there was order in society between Shia's and Sunni's, not civil wars. Oh and al qaeda couldnt get into iraq either. Also, Saddam was supported by US when attacking the kurds and shia's etc.
