Did the War in Afghanistan have to happen?

The New York Times says Taliban fighters brandished Kalashnikovs and shook their fists in the air after the Sept. 11 terrorist attacks, defying American warnings that if they did not hand over Osama Bin Laden, their country would be bombed to smithereens.

The bravado faded once American bombs began to fall. Within a few weeks, many of the Taliban had fled the Afghan capital, terrified by the low whine of approaching B-52 aircraft. Soon, they were a spent force, on the run across the arid mountain-scape of Afghanistan. As one of the journalists who covered them in the early days of the war, I saw their uncertainty and loss of control firsthand.
