The U.S. government issued a warning Oct. 3 advising Americans traveling to Europe to be “vigilant.”
European security forces are far better trained and prepared than their Indian counterparts, and such an attack would be unlikely to last for hours, much less days, in a European country. Still, armed assaults conducted by suicide operatives could be expected to cause many casualties and certainly create a dramatic disruption to economic and social life.
How to be Vigilant Against a Terror Attack
The first question to ask about the Oct. 3 warning, which lacked specific and actionable intelligence, is how someone can be vigilant against such an attack. There are some specific steps that people can and should take to practice good situational awareness as well as some common-sense travel-security precautions. But if you find yourself sleeping in a hotel room as gunmen attack the building, rush to your floor and start entering rooms, a government warning simply to be vigilant would have very little meaning.
The world is awash in intelligence about terrorism. Most of it is meaningless speculation, a conversation intercepted between two Arabs about how they’d love to blow up
The problem is that what appears quite obvious in the telling is much more ambiguous in reality. At any given point, the government could reasonably raise the alert level if it wished. That it doesn’t raise it more frequently is tied to three things. First, the intelligence is frequently too ambiguous to act on. Second, raising the alert level warns people without really giving them any sense of what to do about it. Third, it can compromise the sources of its intelligence.
The current warning is a perfect example of the problem. We do not know what intelligence the

Government Alerts on Terrorism Threats Serve Multiple Purposes
The alert serves another purpose beyond alerting the public. It communicates to the attackers that their attack has been detected if not penetrated, and that the risks of the attack have pyramided. Since these are most likely suicide attackers not expecting to live through the attack, the danger is not in death. It is that the Americans or the Europeans might have sufficient intelligence available to thwart the attack. From the terrorist point of view, losing attackers to death or capture while failing to inflict damage is the worst of all possible scenarios. Trained operatives are scarce, and like any strategic weapon they must be husbanded and, when used, cause maximum damage. When the attackers do not know what Western intelligence knows, their risk of failure is increased along with the incentive to cancel the attack. A government warning, therefore, can prevent an attack.
In addition, a public warning can set off a hunt for the leak within al Qaeda. Communications might be shut down while the weakness is examined. Members of the organization might be brought under suspicion. The warning can generate intense uncertainty within al Qaeda as to how much Western intelligence knows. The warning, if it correlates with an active plot, indicates a breach of security, and a breach of security can lead to a witch-hunt that can paralyze an organization.
Therefore, the warning might well have served a purpose, but the purpose was not necessarily to empower citizens to protect themselves from terrorists. Indeed, there might have been two purposes. One might have been to disrupt the attack and the attackers. The other might have been to cover the government if an attack came.
In either case, it has to be recognized that this sort of warning breeds cynicism among the public. If the warning is intended to empower citizens, it engenders a sense of helplessness, and if no attack occurs, it can also lead to alert fatigue. What the government is saying to its citizenry is that, in the end, it cannot guarantee that there won’t be an attack and therefore its citizens are on their own. The problem with that statement is not that the government isn’t doing its job but that the job cannot be done. The government can reduce the threat of terrorism. It cannot eliminate it.
Defeating Jihadist Terror Cells Cannot be Accomplished Defensively
This brings us to the strategic point. The defeat of jihadist terror cells cannot be accomplished defensively. Homeland security can mitigate the threat, but it can never eliminate it. The only way to eliminate it is to destroy all jihadist cells and prevent the formation of new cells by other movements or by individuals forming new movements, and this requires not just destroying existing organizations but also the radical ideology that underlies them. To achieve this, the

The idea of suppressing jihadist terrorism through direct military action in the Islamic world would be an idea Will Rogers would have appreciated. It is a superb plan from a policymaking perspective. It suffers only from the problem of technical implementation.

It would follow then that the West will have to live with the terrorist threat for the foreseeable future. This does not mean that military, intelligence, diplomatic, law-enforcement or financial action should be stopped. Causing most terrorist attempts to end in failure is an obviously desirable end. It not only blocks the particular action but also discourages others. But the West will have to accept that there are no measures that will eliminate the threat entirely. The danger will persist.
Effort must be made to suppress it, but the level of effort has to be proportional not to the moral insult of the terrorist act but to considerations of other interests beyond counterterrorism. The
