A revelatory account of the cloak-and-dagger Israeli campaign to target the finances fueling terror organizations--an effort that became the blueprint for U.S. efforts to combat threats like ISIS and drug cartels. ISIS boasted $2.4 billion of revenue in 2015, yet for too long the global war on terror overlooked financial warfare as an offensive strategy. "Harpoon," the creation of Mossad legend Meir Dagan, directed spies, soldiers, and attorneys to disrupt and destroy money pipelines and financial institutions that paid for the bloodshed perpetrated by Hamas, Hezbollah, and other groups. Written by an attorney who worked with Harpoon and a bestselling journalist, Harpoon offers a gripping story of the Israeli-led effort, now joined by the Americans, to choke off the terrorists' oxygen supply, money, via unconventional warfare.
