For readers of Lawrence Wright s "The Looming Tower "and Steve Coll s "Ghost Wars "comes an unprecedented exploration of the decades-long hostilities between the United States and Iran, a power struggle that led to a historic nuclear deal. Through economic sanctions, global diplomacy, and intelligence work, successive U.S. administrations have struggled to contain what many view as the Middle East s most alarming foreign policy threat. Meanwhile, Iran has used the overthrow of Saddam Hussein and their own formidable intelligence networks and proxies to undermine America s foothold in the region. From Jay Solomon, chief foreign affairs correspondent for "The Wall Street Journal, "this is the deeply reported, riveting account of a war waged on many levels military, financial, covert. Most don t even realize it is being fought, let alone its depth and far-reaching implications."
