I am not impressed with The Unraveling. It is a biased review of one person's own personal impressions, backed with diplomatic language from the US State Department. I picked up the book during a trip thinking that it would make a good addition to the research that I was doing on Pakistan's battle with extremist organizations, only to find that the writer put the entire blame for the problem at the feet of Pakistan's intelligence service that since 9/11 has been dogged by the US government.
He seemed to go to great extents to not mention the mainstream political parties that support, shelter and encourage these same jihadi groups in their provinces so that he could make the entire base of his argument blaming the ISI. This is more of a memoir of a mid-level diplomat than a true account of the problems that Pakistan as a nation struggles with.
