Don Rassler and Vahid Brown have written one helluva report on the Haqqani network, the folks who have been providing aid and sanctuary to AQ Central for decades. Based on thousands of pages of primary source documents–many not previously released to the public–Rassler and Brown explain how the Haqqanis did (and do) it.
Still not sure you want to read it? The authors borrow network analysis tools from Renaissance Studies to show how the Haqqani network functions. C’mon.
