It is not just his work with the Taliban, it is also his close connections with the ruling circles in Saudi Arabia and potential connections with Saudi intelligence agents in 9/11, and the fact that the CIA failed to take him out on numerous occasions and that the Saudis let him get off the hook for a number of stupid stunts he pulled, he was basically exiled for being something of a dissident.
He was also killed in Pakistan, and Pakistan was at the time a US proxy in the area.
TBH I always suspected 9/11 of being covertly backed by the Pakistanis, maybe even China.
The whole mess with bin Laden just proved the CIA is incompetent.
