This is a question that must have been asked 12 years ago when the US invaded Iraq. Well the initial predictions were positive. The war will be quick, cheap, we will be hailed as liberators, there will be peace, so on and so forth. Of course none of that happened. They were dead wrong, but even me when I witnessed the reports of chaos in Iraq, I could not comprehend that this would happen. What is the worst that can happen? ISIS can happen. The relatively new Islamic terrorist group is different from other organizations because they are successful. They have the oil fields, they are surrounding Baghdad, they have both Iraqi and American weapons in their inventory and they are gaining more ground. This is made worse by their tendency to be very destructive. So far, over 1,700 Iraqi troops have been executed. So yes, that is the worst that can happen and the Bush administration is completely at fault no matter how indirectly this is. Maybe this is a question Obama should consider, especially with an upcoming midterm and a country filled with pissed off liberals.
