GW Bush also largely ignored the search for the mass murderer Bin Laden in favor of the Iraq invasion. In my view this was a crazy diversion of focus and resources based on bizarre assumptions (I remember Bush firing a budget type over his public assertion that Iraq would cost us $ 100 billion - it turns out it cost trillions; bin Laden needed to be nailed to the wall as soon as possible. I agree with Obama on virtually nothing but I will give him credit for taking out bin Laden.
Instead, GWB gave us a "war on terror" that never ends.
