An improper mindset loses wars, and starts them. The WMDs were all an illusion. Saddam Hussain and his followers had nothing to do with Al Quaida. The idea of setting up a democracy in Iraq only gave Iran one fewer enemy and one additional ally, because the controlling people in Iraq were Sunnis but the majority of the people were Shiites, as is the controlling people in Iran. Huge amounts of money were spend on this needless war, and additional huge amounts were spent pacifying anti-war politicians at home with completely wasteful pork barrel spending projects. And all the lost and ruined lives. For nothing.
