Bin Laden attacked the USA in the 90s (the original twin tower attacks). Then issued a Fatwa declaring a Holy War against the USA (https://en.wikipedia.org/wiki/Fataw%C4%81_of_Osama_bin_Laden).
Bin Laden's writings on 9/11 are well published, even on Western Media (https://www.theguardian.com/world/2002/nov/24/theobserver).
There's no doubt in anybody's mind that Bin Laden was involved in 9/11.
> 2. Are we 120% sure we can capture and execute Bin Laden without civilian fatalities?
Of course not. We would have preferred for the Afghan government (aka: the Taliban) to cooperate with us. But they didn't.
> 3. Why western media didn't give enough voice to Taliban at that time?
We have Bin Laden's writings published and the Taliban's writings published. What exactly is missing from their argument that you want published?
> 4. Are we sure war wasn't lobbied?
Oh, Cheney was definitely a Warmonger. But that doesn't make the Afghan War a wrong move.
