I certainly don't fault GWB from going into Afghanistan and dealing with the Taliban. His greatest mistake was not finishing off the job in Afghanistan before diverting the majority of US assets to invade Iraq to eliminate WMD that didn't exist and enhance Iranian power in the region. While he was doing that the Taliban was able to reconstitute and to this day is threatening to return to power in Afghanistan. So now we have terrorists entrenched in both Iraq and Afghanistan and Syria and Yemen and Somalia after spending trillions and thousands of American soldier lives. Good job GWB.
Why didn't Obama rectify the situation in Afghanistan, and Iraq over the past eight years?
For the record, the Democrats voted to invade Iraq also, based on Allied intel. Hillary, Kerry, Schummer, Pelosi, Reid, etc.
