Book excerpt: This concise and balanced account details Pakistan's turbulent 73-year history of civil war, military coups, political assassinations, wars with India, cooperation with the U.S. during the Afghan-Soviet war, and events following 9/11. An unpredictable nuclear nation, Pakistan has been variously described as the center of international terrorism, the world's biggest nuclear weapons proliferator, the most dangerous place in the world and, some experts predict, the most likely site of the world's first nuclear war.
