​Harpoon author Nitsana Darshan-Leitner is director of Tel Aviv based organization Shurat HaDin, which works with lawyers, law enforcement, and intelligence agencies to fight Israel's enemies. A key tool used by Shurat HaDin is to "follow the money", using a variety of means to identify and dry up sources of funding for terrorist groups and activities. And it's those activities, direct and indirect, which is the subject of this book.
It was interesting to read about how focusing on the financial side of terrorism activities gained in prominence over the retribution and punishing individuals or terrorist leaders.
This is an Israeli book written from an Israeli perspective, and the author spends a lot of time detailing a number of Palestinian attacks against the Jewish State, which to me got repetitive, overly detailed, and a distraction from the main point of the book. However, the wide-ranging techniques identified in the book can be and are being used by other nations against terrorist organizations of all stripes. And the effectiveness of those techniques are being shown to be important and effective in that regard. ( )
