Uhhhhh……Massoud got assassinated by the Taliban because he was the Taliban’s enemy, not for any other reason. Not sure what exactly you are trying to say.
Had nothing to do with the USA.
There is one narrative/conspiracy theory that says that the Taliban struck a bargain with OBL in which, in exchange for al-Qaeda’s assistance in bumping off Massoud, the Taliban would agree to protect OBL on 9/11, but that has never been proven. There’s no evidence to support that, only conjecture, so I don’t try to connect the two.
The timing could have been a mere coincidence. I wouldn’t assume anything else.
Had Massoud still been alive when 9/11 happened, I’m sure he’d have seized the chance to lead his Northern Alliance with us in the mutual fight against the Taliban.
That does NOT mean that he could have ultimately ruled the entire country.
I’m sure he would have had a prominent leadership position in the country, post-Taliban, but it’s doubtful that enough Pashtoons would have supported him to allow him to be President. Perhaps he could have become Minister of Defense, as his #2 guy, Marshall Fahim, did, or possibly VP, but not President.
Most Afghans I talked to, even his fellow Tajiks, seemed to feel that way.
His popularity was/is more regional than national. As I said, in provinces like Panjshir and Parwan, his picture is everywhere, and he’s regarded as a great hero and martyr.
But in heavily Pashtoon provinces like Kandahar and Kunar, he has almost no following.
