In February 1989, the CIA's chief in Islamabad famously cabled headquarters a simple message: "We Won." It was an understated coda to the most successful covert intelligence operation in American history. InWhat We Won, CIA and National Security Council veteran Bruce Riedel tells the story of America's secret war in Afghanistan and the defeat of the Soviet 40th Red Army in the war that proved to be the final battle of the cold war. He seeks to answer one simple questionwhy did this intelligence operation succeed so brilliantly? Riedel has the vantage point few others can offer: He was ensconced in the CIA's Operations Center when the Soviet Union invaded Afghanistan on Christmas Eve 1979. The invasion took the intelligence community by surprise. But the response, initiated by Jimmy Carter and accelerated by Ronald Reagan, was a masterful intelligence enterprise. Many books have been written about intelligence failuresfrom Pearl Harbor to 9/11. Much less has been written about how and why intelligence operations succeed. The answer is complex. It involves both the weaknesses and mistakes of America's enemies, as well as good judgment and strengths of the United States. Riedel introduces and explores the complex personalities pitted in the warthe Afghan communists, the Russians, the Afghan mujahedin, the Saudis, and the Pakistanis. And then there are the Americansin this war, no Americans fought on the battlefield. The CIA did not send officers into Afghanistan to fight or even to train. In 1989, victory for the American side of the cold war seemed complete. Now we can see that a new era was also beginning in the Afghan war in the 1980s, the era of the global jihad. This book examines the lessons we can learn from this intelligence operation for the future and makes some observations on what came next in Afghanistanand what is likely yet to come.
