I can help you with that: you look at WHY did US go into Afghanistan in the first place and then look at whether or not it achieved it. The US went into Afghanistan: 1. To take control over Trans-Afghan pipeline (which should've given US a leverage over Asia); 2. To take control over Afghanistan natural resources (the USSR made a good progress in mapping them out and making plans as to their extraction); 3. To take control over Afghanistan to the extent necessary to turn it into a platsdarm for a future invasion of Iran. 1. 2. While US/UK/etc. are dying over there, China quietly made itself comfortable on the Pakistani end of the pipeline and together with Russia, as part of SCO, is working on Afghanistan's economic projects... 3. Is Afghan's central government strong enough and pro-US enough to consider the country a safe platsdarm for US agression against Iran?
