I’m close with several Uzbeks (including Uzbek Jews!) And honestly, just as in the Middle East (yes even the Middle East, I mean just look at the protests in Iran) - of course not everyone is a Sharia law abiding extremist.
But major terror suspects in the U.S. hailed from the Caucuses or former Soviet region. The brothers who carried out the Boston Marathon attacks, the car ramming thing in New York a few weeks ago...I think from Uzbekistan and here on visa lottery...etc...
The Boston terrorists were Chechens and they are the worst of the worst. The latest attackers are Uzbek & that bothers me since the Uzbeks I worked with were OK folks whose women dressed as they pleased & they all seemed to like Americans.
There were suicide bomber attacks in Tashkent in that spring of 2004 & the locals asked us not to judge them because of the extremists.
Uzbeks, like Persians, celebrate their pre-Islamic history.
