But there are multiple questions which should be answered:
1. are we 110% sure that Bin Laden ordered the attack? I am not trying to defend him, but you know there are many organizations who can do that attack, including multiple organizations funded by CIA (don't forget Bin Laden was initially funded by CIA), maybe government could prevent attack but didn't prevent, because they were also interested in natural resources of Afghanistan?
2. Are we 120% sure we can capture and execute Bin Laden without civilian fatalities? if civilian fatalities can't be avoided, did we have numbers in mind, how many people will get killed?
3. Why western media didn't give enough voice to Taliban at that time? If enough people listened to them, maybe US could make public negotiation and if negotiation fails publicly, then everyone would definitely know Taliban is to blame for this war. In reality, US just said, we are super power, we can do whatever we want.
4. Are we sure war wasn't lobbied? You know, US sells lots of weapons, they sometimes need to test, are we sure that war wasn't lobbied? where did 2T$ go? Do you think all were eaten by corrupt Afghan government? even 10% of it would be 200B which would create 100 billionaires.
I am not defending Taliban or Bin Laden, just showing how decisions made was wrong and I still doubt US can make right decision. Now Afghanistan has lots of uneducated people, who lost their families, children. Do you think they would just forgive? Who can guarantee that they won't come over to US and start killing people?
