The IMU, and the more mainstream Hezb ul-Tahrir (which is such a hit at freshmen's fairs at colleges in the British Midlands) promote an Islam derived from Saudi or Pakistani ideologies, which has little echo in Turkestan. For example, some zealots have tried to force Uzbek women to change their brilliant dresses, the most beautiful costume in the world, for the all-over tent known as a chadari or burqa. Saudi Arabia and Pakistan's Interservices Intelligence (ISI) have, anyway, been obliged since 11 September to stop playing silly buggers with the radicals in central Asia if they want to stay friends with the US. To cap it all, Russia, China and the US are now co-operating against what they call terrorism as never before.
