I've been looking back on the early years of the war in Afghanistan lately with a few good books:

I just finished reading The Art of Intelligence: Lessons from a Life in the CIA's Clandestine Service. It covers a variety of issues from the CIA's CTC in the buildup to September 11 to lessons learned from the first few years of war, but what I found most interesting was the author's description of his experience serving in Africa. Based on current events in Libya, I found this information to be timely and informative.

I've moved on to a book the previous author recommends, First In: How Seven CIA Officers Opened the War on Terror in Afghanistan . This covers the JAWBREAKER team's entry into Afghanistan and their challenges in the opening days of the war. Very interesting so far.
