Am currently reading this book. It's a true account of how the U.S. of A and the CIA made their way into the Afghan War and assisted the mujahideen to drive the Red Army out while inadvertently helped shaped the world as we know it today. It's an honest telling of the cloak and dagger story behind the war.
While the theme is serious, it is at times funny as hell especially when it involves the exchanges between the 2 protagonists and those who dare crossed their paths or irritated them. Also there is one funny account of the role and involvement of mules during the war and the beasts' special place among the Muj (as the mujahideens are known to the Americans).
The book also gives insight on the workings of the US government machinery and how the US dictate the world affairs during the Cold War period.
It is a good book. I have another 100+ pages to go.
