Central Asia Primer

Here's a nice summary of the situation in Central Asia, as well as on how the US views the region:

U.S. policymakers increasingly view Central Asia as a transit point to somewhere else. It is a region through which oil and natural gas flow to Europe, reducing U.S. allies' dependence on Russian energy supplies. It is a region through which fuel, food, and spare parts flow to surging U.S. and NATO forces in Afghanistan, reducing their dependence on a precarious Pakistani supply route. Officials and policy experts even have a new name for this region that captures its status as a logistical intermediary, rather than a set of distinct countries that matter in their own right: They call it the "Northern Distribution Network."
