How would society and politics had been affected if on September 11 2001 if the US military had shot down the four hijacked planes before they hit their targets? Besides the obvious of the World Trade Center still standing, would there have been such a move to then to after terrorism in Afghanistan? How would this have affected the build up to the Iraq War?
I can imagine a great deal of public outcry when the US military essentially kills hostages, and I am not sure if people would have believed that the disaster would have been as bad as it was were the planes not shot down.
