In ''Descent Into Chaos: Pakistan, Afghanistan and the Threat to Global Security'' Ahmed Rashid explores the most volatile and dangerous region in the world. The war on terror is being lost - but not just in Iraq. As this devastating book shows, the real crisis zone now lies in central Asia. Veteran reporter Ahmed Rashid has unparalleled access to the region and knows its leading players, from presidents to warlords. Here he documents how closely Pakistan's US-backed regime is linked with extremists; how broken promises in Afghanistan have led to a resurgent Taliban fed by drugs money; and how the largest landmass in the world is now a breeding ground for terrorism. In this story of squandered opportunities, misguided alliances and double-dealing, Rashid pinpoints with chilling accuracy where the true threat to our global security comes from.
