The fate of Masood was the result of CIA and State Dept. bungling under Clinton regime. Taliban was created by Pakistan with the full blessing of U.S. He was badly outnumbered. He had to find allies who can help him. Iran hates Pathans, i.e., Talibans, the rabid Sunni fundamentalist too militant even for Shi'te Iranians' taste. Besides, they have mutual enmity reaching back centries. Then Masood's onetime nemesis, Russians and their allies, Uzbek militia of Rashid Dostum. In short, he allied with ex-commies, their allies and Shi'ite regime in Iran. While Masood's regime would have been islamic republic of some kind, I don't think it would be on the same level as Iran or current Pakistan. And my guess is that he won't be the one who spearhead the international Jihad.
