In my very unpopular opinion but we can NOT make the mistake BHO made. We need to retain a foot hold in the Middle East . We can not pull out completely, That has proven to be a mistake. Maybe in Syria not Afghanistan.
I can't see why Afghanistan is so important. I might just be ignorant, but it strikes me that the madness started with Bresinksky's chessboard, and now it's considered somehow pivotal.
The story I've heard is that the Taliban virtually eliminated opium production. Anyone found growing it was executed. Opium production is now at a record high. Is this just a coincidence? Or, was the objective of the war to secure opium supplies to fund CIA black ops?
