W. Bush confused the Al Qaeda with the Taliban.
The Taliban are religious and political leaders of Iraq, previously allied with the US, who captured bin Laden and his top aides merely 9 days after the 911 attack and offered to turn them over to the US.
W. Bush ordered the Taliban to immediately turn over bin Laden, but the Taliban had to vote on that (and they had no seat of power (Soviets destroyed their capital, so the Taliban roamed Afghanistan as individuals). So the vote was slow, and W. Bush was too impatient to wait.
Taliban's law is harsh, by US standards (hands get chopped for theft). Yet, US laws are lax by Taliban standards. OJ apparently stabbed to death Nichole Brown Simpson and Goldman, yet got off scott free.
After losing a thirty year war in Iraq, the Taliban is back in power in Afghanistan. The only thing gained is bitter resentment, and the belief that hot tempers motivate massive armed forces.
We can't kill 1,000,000 Iraqs (innocent of terrorism), then object to a few criminals facing harsh sentence.
