This is a topic that hasn't gotten much attention, but is certainly interesting (especially the economic take in my opinion). As the West pulls out of Afghanistan, China and India are preparing to go in and mine/trade the country's vast resources. A story of incentives (as usual) and how they lined up so the US might end up paying the security bill and India and China will reap economic benefits (although arguably that could end up helping up in the long run too).
