Re: Uzbeks
Afghani uzbeks are not pro-Taliban and I doubt woul dbe doing the things they are doing UNLESS they are trying to destabilise pakistan via RAW/CIA etc. Politically Uzbeks are/were more left wing in Afghanistan than other groups. Dostum is/was a communist/part-time communist. There are no islamic parties within Afghani Uzbeks unless they are very small or support other Afghan groups such as Masood's group.
Uzbeks from Uzbekistan have a movement for Shariah with the government clamping down on them - it is most likely that Uzeks fighting for Shariah will be from Uzbekistan
