in waziristan? i doubt it.
under taliban rule in afg, the uzbeks were part of the evil northern alliance. now when northern alliance is in power, and the taliban have retreated to waziristan and assorted adjoining tribal areas, why would uzbeks be there? it doesnt even make sense. unless someone is trying to hide the fact that these were just local waziri terrorists.
Different Uzbeks. The Northen Alliance Uzbeks were Afghanis of Uzbek ethnicity. They were led by Rashid Dostum, an Afghani uzbek politician.
The Uzbek militants in Pakistan are not affiliated with Dostum - they are actual Uzbekistanis from Uzbekistan, not Afghanistan. They were forced out of their country by its dictator after the militant effort to overthrow the Uzbek government failed, and they found welcome and shelter initially from Al-Qaeda in the late 90s and following the rapid demise of Al-Qaeda earlier this decade, in the communities that were sympathetic to Al-Qaeda.
These are Uzbeks in exile - they can't return to Uzbekistan because the government wants to kill them, but having failed to create an "Islamic" state by force in Uzbekistan they are trying to help the Pakistani Taliban do the same in the FATA.
