This RAND report examines 648 terrorist groups that have been active between 1968 and 2006. The authors want to answer a pressing question: what makes terrorists stop being terrorists? The authors conclude that military force is the least effective way to end terrorism. In fact, terrorist groups are more likely to disband because they achieve their goals (10% of the time) than because a primarily military strategy has defeated them (7%). When a political solution (43%) is not possible, the most effective way to end terrorism is through effective policing and intelligence (40%).
The authors argue that the "war on terror" is an ill-advised concept. America's military strategy has not diminished al Qaida's global strength at all; al Qaida carried out more attacks in the five years after 9/11 than in the five years prior. In fact, the invasion of Iraq in 2003 may actually have prevented the US from capturing al Qaida's core leadership in Central Asia. The "war on terror" also glorifies terrorists, diverts US resources from more effective policing and intelligence tactics, and turns local Muslims against the United States. (The authors show that local support is crucial to success. The near-disappearance of al Qaida from Iraq's al Anbar province, they say, is due not to increased US troop strength but to the rise of an indigenous police force, recruited mostly from militias.)
The RAND Corporation is hardly a peacenik stronghold. It is virtually an arm of the Defense Department. This study tells me little I did not already know, but I welcome it as additional evidence that the Bush administration has weakened America's national security.
