Gregg Easterbrooke imagines if Bush had, in fact, attacked Osama prior to 9/11:

When dozens of U.S. soldiers were slain in gun battles with fighters in the Afghan mountains, public opinion polls showed the nation overwhelmingly opposed to Bush's action. Political leaders of both parties called on Bush to withdraw U.S. forces from Afghanistan immediately. "We are supposed to believe that attacking people in caves in some place called Tora Bora is worth the life of even one single U.S. soldier?" former Nebraska Senator Bob Kerrey asked.

When an off-target U.S. bomb killed scores of Afghan civilians who had taken refuge in a mosque, Spanish Prime Minister Jose Aznar announced a global boycott of American products. The United Nations General Assembly voted to condemn the United States, and Washington was forced into the humiliating position of vetoing a Security Council resolution declaring America guilty of "criminal acts of aggression."

Brilliant.
