Well Al Qaeda got there first, they had been working on NWFP and KPK for a while prior to 9/11. They knew how basic the people are there and radicalized them so when the time came they would do as they say and support. Even offered their women to them, still do today. That's why Mullah Omar was hiding out there. Taliban had their "safe haven". They basically made the people in this area their bitches. Musharraf needed the support of his people for Pakistan to present a unified front but half of the country was caught in a day dream of a pan Islamic Afghan empire and bacha bazi child molesting Afghans on white horses coming to liberate Pakistan from the "kuffar" leadership and invade India on horseback and swords. Bizarre fantasy, I guess anything but Pakistan taking the glory
Osama promised the Afghans greater Afghanistan which would include FATA and KPK but in reality he knew the Afghans were equally as simple and stupid, he really wanted the collapse of Pakistan and access to the nukes. It was all a ruse.
Pakistan had already lost the ideological war before 9/11, if they had taken the warning from the yanks after the 94 twin tower car parking bombing, perhaps this could have been avoided.
But what did they do instead? They supported the Taliban regime to take over during the civil war
Absolute f**king clowns, Pakistani deep state are great at scoring own goals.
