U.S. Army colonel turned academic, Bacevich (The Limits of Power) offers an unsparing, cogent, and important critique of assumptions guiding American military policy. These central tenets, the "Washington rules"--such as the belief that the world order depends on America maintaining a massive military capable of rapid and forceful interventions anywhere in the world--have dominated national security policy since the start of the cold war and have condemned the U.S. to "insolvency and perpetual war." Despite such disasters as America's defeat in Vietnam and the Cuban missile crisis, the self-perpetuating policy is so entrenched that no president or influential critic has been able to alter it. Bacevich argues that while the Washington rules found their most pernicious expression in the Bush doctrine of preventive war, Barack Obama's expansion of the Afghan War is also cause for pessimism: "We should be grateful to him for making at least one thing unmistakably clear: to imagine that Washington will ever tolerate second thoughts about the Washington rules is to engage in willful self-deception. Washington itself has too much to lose."
