The Next Decade (13 page)

The purpose of war, according to von Clausewitz, is to impose your will on another nation by rendering that other nation incapable of resisting. The primary means for doing this is to destroy the nation’s military, or to undermine the population’s will to resist. Instilling terror can destroy an army; for example, the Mongols paralyzed their enemies with the knowledge of their relentless and ruthless cruelty. The Greek city-states would fight their wars to the bitter end, spurred on by fear of the slavery that awaited them if they were conquered. So the net effect of terror is hard to predict.

During World War II, neither the Germans nor the British made any bones about the purpose of what the British called “nighttime area bombing.” The targeting of civilians was a tactic designed to generate terror among the public, in the hope that the civilians would at the very least become less effective in running the wartime economy, and at the extreme possibly rise up against their own regimes. In Japan, the Americans pursued the same ends by using incendiary devices, taking advantage of the fact that most Japanese buildings were made of wood. In three days of conventional bombing over Tokyo, U.S. air forces killed 100,000 Japanese civilians, more than were killed at Hiroshima. Yet until the introduction of the atomic bomb, the terror strategy failed, just as it had failed in both Germany and Britain. Rather than destroying faith in the government, the bombing of civilian areas rallied the public to support the war effort. The attacks inspired outrage while making it easy for the targeted governments to portray the consequences of defeat as being too horrible even to contemplate. If the enemy was willing to go to such lengths to divert resources during a war simply to kill civilians, imagine what they would do when the war was over. Terror made it easy to demonize the enemy and made surrender unthinkable.

In conventional warfare, terror is delivered by massed force. But terror also can be delivered through a covert operation by a very small number of individuals: a commando attack. These operations were once generally confined to assassinations, but after the invention of high explosives—and force multipliers for high explosives, such as airliners—commando terrorism focused on civilian targets with the goal of producing casualties as an end in itself.

It is important here to distinguish carefully between commandos whose goals are military and those whose targets are civilian and whose purpose is terror. The French Resistance in 1944 attacked German transport facilities in an attempt to undermine their invader’s ability to wage war directly. The terror commando’s goal, however, is not to harm the enemy’s military but to undermine enemy morale by generating a sense of vulnerability. Sometimes the audience isn’t even the target country but public opinion elsewhere, as with the attacks of September 11.

By generating fear, helplessness, and rage, terrorism transforms public opinion, which then demands that the government provide protection from terrorists and punish such people for their actions. The more effective the terrorist attack is, the more frightened the population is, and the more compelled the government is to respond aggressively and visibly. Once again, in the face of terror, the president must convince the public that he shares their sentiments while taking actions that appear to satisfy their cravings both for security and for revenge.

One such largely symbolic action taken since September 11 has been the attempt to bolster the airport security system. Despite billions of dollars and untold measures of passenger frustration, a terrorist with training can still devise any number of ways to get explosives or other devices through the system. Some terrorists might be deterred, and the system will find others. But while increased airport security can decrease the threat, it cannot stop it.

There is simply no security system that is both granular enough to detect terrorists reliably and efficient enough to allow the air transport system to function. El Al, Israel’s airline, is frequently held up as an example, but El Al has thirty-five planes. According to the Bureau of Transportation Statistics, the combined American air fleet has nearly eight thousand planes and over twenty-six thousand takeoffs per day. The Transportation Security Administration says it screened 1.8 million passengers per day on average in 2009. These are staggering numbers.

What the limitations of airport screening tell us is that if al Qaeda failed to strike the United States again during the first decade of the twenty-first century, it was not because of security precautions per se. It is even doubtful that the people who design the airport security system expect it to work. Their real objective is to calm the public by ostentatiously demonstrating that steps are being taken. The greater the ostentation and inconvenience, the more comforting the system appears.

But the increasing sophistication of explosives makes it possible to kill dozens of people with a device carried by an individual, hundreds of people with a device hidden in a car or truck, and thousands of people with an aircraft that acts as an explosive. The world is awash in such explosives, and the borders of the continental United States are about nine thousand miles long. The United States is also a trading country, and ships and planes and trucks arrive daily. Any one of those conveyances could contain people and explosives prepared to kill other people. It is also true that among 300 million Americans, there could be any number of homegrown terrorists preparing to strike at any time.

For these reasons, true homeland security in a country like the United States is impossible, and the task will remain impossible in the next decade. There are no silver bullets. Eliminating Islamist terrorism is similarly impossible. It is possible to reduce the threat, but the greater the reduction we hope to achieve, the greater the cost. Given unlimited possibilities and limited resources, it is safe to say that there will continue to be terrorist attacks on the United States, regardless of the efforts being made.

The president of the United States must know this with crystal clarity, and he must always act on the basis of what he knows, but he must never admit these limits to the public. He must constantly demonstrate that he is doing all he can to destroy the enemy and to protect the homeland, and he must always convey a sense that the elimination of Islamist terrorism is possible, all the while knowing that it is not.

As we embark on the policy decisions of the next decade, the larger point is that turning all American resources to an end that is unobtainable, against a threat that can and will have to be endured, is not only pointless but something that can create windows of opportunity for other enemies and other assaults.

While terrorism can kill Americans and can create a profound sense of insecurity, the obsessive desire to destroy terrorism can undermine—as it already has undermined—the United States strategically. This is an important point for the leaders of the next decade to consider. This is why even though thousands of Americans might be killed by terrorists—myself and my loved ones among them—terrorism should not be elevated to the status of an issue towering above all others. At all times, strategy must remain proportional to the threat.

TERROR AND WEAPONS OF MASS DESTRUCTION

Another unpleasant reality that will loom over the next ten years, which needs to be considered separately, is weapons of mass destruction. The existence of such weapons will occasionally prompt severe responses from the presidents who lead us. The damage that a nuclear device might do would dwarf that of conventional terrorism. Whereas conventional terrorism is rarely strategic, weapons of mass destruction can have a profound effect on the material condition of the country.

To turn our attention back to Bush, there was in fact more to his response to September 11 than simply stopping conventional terrorism. After that day, the Bush administration received intelligence that a nuclear device—a Soviet-era suitcase bomb, to be specific—had been stolen and might be in the hands of al Qaeda. Thus the specter that haunted the administration in the closing months of 2001 was that at any moment an American city might be destroyed by a nuclear weapon.

It was this threat that defined the Bush administration’s initial efforts. The president and vice president were never in the same city at the same time, and all intelligence and security services were directed to find the weapon. It would appear that they never found it, or it may never have existed. After years of mishandling, it may have malfunctioned, or it may have been intercepted and the government chose not to reveal its existence.

Regardless, weapons of mass destruction, particularly nuclear devices, represent a class of threat that cannot be tolerated. It would take many nuclear weapons to actually destroy the infrastructure and population of the United States, but a single attack by a nuclear weapon could destabilize public morale to such an extent that it would paralyze the country for an extended period of time.

In a small terrorist attack in which dozens die, like the suicide bombings in Israel, the probability that any one individual out of a population of 300 million will be a victim is small. The probability of dying from an ordinary accident or from disease in the next year is far higher than that of being killed in a suicide bombing. The events of September 11 distorted the perception of danger for a while, and people avoided flying, and perhaps avoided crowded places and landmark buildings. But as time passed, the sense of being subject to attack declined. The danger was on most people’s minds when they went to the airport, and perhaps when they entered the Sears Tower or the Empire State Building or the Capitol. But over time, the perceived risk of being in the wrong place at the wrong time was assimilated into the general background noise. As this happened, for many people the demand that all steps be taken to guard against terror turned to dismay at what they regarded as excesses, inconveniences, and intrusions.

With weapons of mass destruction, the probabilities and the persistence of fear are different. Assume that an American city were destroyed by a nuclear device. Once a WMD attack had destroyed one city, the number of targets a terrorist might want to hit next would be relatively small, but for anyone living in one of the major cities, there would be the immediate, reasonable fear that the enemy had more such weapons and that at any instant they might strike again.

From a terrorist’s perspective, wasting a nuclear weapon on Spokane, Washington, or Bangor, Maine, makes no sense. It is the major cities that are the centers of political, economic, and social life. For them to be evacuated by frightened citizens would bring not only chaos but abandonment of entire economic and communications systems while millions of refugees fled to nowhere in particular. This response to the fear of mass annihilation from a completely random threat would be the ultimate objective of terrorism using WMDs.

Terrorists of many stripes—Palestinian, European, Japanese—have been operating since the late 1960s, and most of these groups would have jumped at the chance to inflict the kind of damage a weapon of mass destruction can engender. Many of these groups have been technically far more sophisticated than al Qaeda. So why has there never been an effective attack with a weapon of mass destruction?

The simple answer is that while constructing and deploying a WMD is easy to imagine, it is very difficult to execute. Existing weapons are relatively few, heavily guarded, difficult to move, and likely to kill the terrorist well before the terrorist gets a chance to kill anyone else. There have been many reports of Soviet-era nuclear weapons, and biological and chemical weapons, being available on the black market, but most of the offers were made by intelligence agencies trying to lure terrorists into a trap. If you were a terrorist offered a suitcase nuke by a former Soviet colonel, how could you possibly tell whether what you were looking at was the real thing or just a box stuffed with wires and blinking lights? The same uncertainty would have to hold for chemical or biological weapons as well. Intelligence services don’t have to know who is selling real WMDs in order to scare away the customers, and the allure of acquiring these weapons contracted considerably when the number of intelligence officers offering them for sale as entrapment outnumbered legitimate offers by one hundred to one.

There is, of course, the option of making such a weapon yourself, and every year some undergraduate posts a diagram of how to build a nuclear device. Between that sketch and success are the following steps: acquiring the fissile material, along with all the necessary circuitry and casings; acquiring the machinery needed to machine the fissile material to the precise tolerances needed in order to detonate it; engaging the experts who could actually do these things once you had the material and the equipment; finding a very secure facility where these experts could work and live, and so on. The chances of being detected are compounded at each stage of this torturous process. Even if you could acquire the highly guarded fissile material, the machines needed for producing a nuclear weapon are highly specialized, and their manufacturers are few and far between. When a private individual shows up with his American Express card to order one of these machines, the chances that he will be detected are very good indeed.

With biological and chemical weapons, you add to these same risks the likelihood that the only person you’ll kill will be yourself and your immediate accomplices. Chemical and biological weapons carry an extra layer of complexity in that they have to be dispersed. When a Japanese group released sarin, an extremely deadly nerve gas, in a Tokyo subway, the contamination remained localized and only a few people were killed, not the substantial numbers the terrorists had hoped for. People always speak of how a speck of this or that could wipe out an entire city. Certainly—but first you have to figure out how to spread it around.

Only one country ever produced a nuclear weapon from scratch, and that was the United States. The British got their nukes in compensation for their contribution to the American research effort. The French also acquired the technology from the Americans, which they then regifted to Israel. The Russians stole the knowledge from the Americans, then transferred it to both the Chinese and the Indians. The Chinese gave the technology to the Pakistanis. The point is, the development of these weapons through an independent research program is enormously difficult, which is why Iran is still struggling and North Korea has never gotten it quite right.
