This is the eighth part in a series of eight exploring why the United States suffered no follow-up terror attacks after 9/11. To read the series introduction, click here.
The RAND Corp. is headquartered in a blindingly white temple of reason a few blocks from the Pacific Ocean in Santa Monica, Calif. It was here—or rather, next door, in the boxy international-style offices it inhabited for half a century before moving four years ago into a new $100 million structure—that America's Cold War nuclear strategy of "mutual assured destruction" was dreamed up. Also, the Internet. Created by the Air Force in 1948, the nonprofit RAND would "invent a whole new language in [its] quest for rationality," Slate's Fred Kaplan wrote in his 1983 book The Wizards of Armageddon.
RAND is the cradle of rational-choice theory, a rigorously utilitarian mode of thought with applications to virtually every field of social science. Under rational-choice theory, belief systems, historical circumstances, cultural influences, and other nonrational filigree must be removed from consideration in calculating the dynamics of human behavior. There exists only the rational and orderly pursuit of self-interest. It is the religion that governs RAND. "You can leave your backpack in my office," RAND senior economist Darius Lakdawalla told me as we headed for a conference room. "There's no theft at RAND." I asked whether "externalities" were permitted anywhere inside the building. He chuckled politely.
Lakdawalla and RAND economist Claude Berrebi are co-authors of "How Does Terrorism Risk Vary Across Space and Time?" a 2007 paper. (To download a copy, click here and pay $30. To download an earlier draft of the same paper free of charge, click here.) An underlying assumption of Berrebi and Lakdawalla's analysis is that—contrary to arguments put forward by game theorist Thomas C. Schelling; Max Abrahms of Stanford's Center for International Security and Cooperation; and Marc Sageman, a forensic psychiatrist and former CIA case officer—terrorists pursue concrete goals in a rational way. On the small-bore tactical level, Berrebi says, terrorists are very rational. It's entirely possible, Lakdawalla explains, to pursue an irrational goal in a rational manner. Berrebi cites terrorists' tendency to use suicide bombers only when no other alternatives are available. In general, terrorists prefer poorly protected targets to well-protected ones. "When stuff becomes harder to hit," Lakdawalla says, "terrorist groups, like anyone else, tend to look for easier opportunities." Don't worry about getting killed at the airport, where security measures have proliferated. Worry about getting killed at the shopping mall, where your only protection is a bored security guard.
When Schelling, Abrams, and Sageman argue that terrorists are irrational, what they mean is that terror groups seldom realize their big-picture strategic goals. But Berrebi says you can't pronounce terrorists irrational until you know what they really want. "We don't know what are the real goals of each organization," he says. Any given terror organization is likely to have many competing and perhaps even contradictory goals. Given these groups' inherently secret nature, outsiders aren't likely to learn which of these goals is given priority.
One goal inherent in the 9/11 attacks was to do harm to the United States. In "The Terrorists-Are-Dumb Theory" and " The Melting-Pot Theory," we reviewed the considerable harm that the furious U.S. response to 9/11 caused al-Qaida. But that response harmed the United States, too. Nearly 5,000 U.S. troops have died in Iraq and Afghanistan, and more than 15,000 have come home wounded. More than 90,000 Iraqi civilians have been killed and perhaps as many as 10,000 Afghan civilians; in Afghanistan, where fighting has intensified, more than 2,000 civilians died just in the past year. "In Muslim nations, the wars in Afghanistan and particularly Iraq have driven negative ratings [of the United States] nearly off the charts," the Pew Global Attitudes Project reported in December. Gallup polls conducted between 2006 and 2008 found approval ratings for the U.S. government at 15 percent in the Middle East, 23 percent in Europe, and 34 percent in Asia. To be sure, civilian casualties have harmed al-Qaida's standing, too, as I noted in "The Terrorists-Are-Dumb Theory." But to whatever extent al-Qaida hoped to reduce the United States' standing in the world, and especially in the Middle East: Mission accomplished. The Pew survey found most countries anticipated an improvement under President Obama, who already has ordered that Guantanamo be shuttered and that the Bush administration's creative interpretations of the Geneva Convention be revoked. But with the Obama administration escalating troop levels in Afghanistan and a growing sense that U.S. forces will remain in Iraq for years to come, the United States won't be loved by the Muslim world anytime soon.
Rational-choice theory is most at home with economics, and here the costs are more straightforward. In March 2008, the Nobel Prize-winning economist Joseph Stiglitz, and Linda Bilmes of Harvard's Kennedy School of Government, put the Iraq war's cost at $3 trillion. In October 2008, the Congressional Research Service calculated, more conservatively, an additional $107 billion for the Afghanistan war and another $28 billion for enhanced homeland security since 9/11. According to CRS, for every soldier the United States deploys in Iraq or Afghanistan, the taxpayer spends $390,000. Let me put that another way. Sending a single soldier to Iraq or Afghanistan costs the United States nearly as much as the estimated $500,000 it cost al-Qaida to conduct the entire 9/11 operation. Not a bad return on Bin Laden's investment, Berrebi says. President Bush left office with a budget deficit of nearly $500 billion, and that's before most of the deficit spending that most economists think will be required to avoid another Great Depression even begins. "We are facing the recession starting from a worsened standpoint," Berrebi says. Al-Qaida may not be the only reason, but it certainly helped.
