I suppose they could simply have just let ISIL reign supreme.Iraq was an illegal war. You cannot wipe out hundred of thousands of innocent lives in the name of fighting a terrorist group and then claim some kind of victory. That makes America and their allies the terrorists. It may have been successful in rendering a terrorist group ineffective but the path they took to achieve that goal included the death of over 1 million people renders that everything they say they achieved an abject failure.
When faced with impossible options you will choose one.I was saying it was America committing the sick and repulsive war crimes in Iraq and all the American and European decision makers who had a hand in that atrocious illegal way should be dragged in front of the Hague.
