As news of a new “credible” threat swept across the nation on the 10th anniversary of 9/11, Americans were abruptly reminded that terrorism is always one bad day away from being issue No. 1.
In the latest case, one report said at least three people—one believed to be a U.S. citizen—entered the U.S. in August to plan a car-bomb attack against Washington, D.C., or New York. The suspected terrorists are thought to have come from Afghanistan or Pakistan, and at least two rental trucks are being sought nationwide. White House officials confirmed that President Obama had been briefed on the "specific" terrorism threat.
Too often, 10 years after the worst terrorist attacks in our nation’s history, we sometimes fall into a false sense of security as a degree of 9/11 amnesia takes hold; a desire to recast the attacks as a tragic isolated incident.
The facts tell a very different story. The record shows that there have been at least 45 jihadist terrorist attacks plotted against Americans since 9/11—each of them thwarted by a combination of intelligence work, policing and citizen participation.
And these are just the plotted attacks that we know about through public documentation—the real number of credible plots is no doubt much higher. No truly authoritative list exists because of the preponderance of classified information, although organizations such as the Heritage Foundation have published detailed lists in the past. An additional problem in coming up with a comprehensive list lies in consistently defining the parameters of thwarted attacks. The plots also are of varying degrees of seriousness, from some that were days from causing mass bloodshed to others that were twisted ambitions caught well before fruition.
The list published below comes as close as I could, using public sources and past lists—and it was reviewed by both government and academic organizations that track terrorist attacks.
Since 9/11, there have been devastating terror attacks in cities like London and Madrid. But America has so far batted 1,000 against the constant stream of civilian-targeted terror threats, though trends show the types of plots are changing to an increase of military targets (think the deadly shooting spree at Fort Hood by Army Maj. Nidal Malik Hassan) and Americans’ training overseas for the purpose of terrorism.
Professor Erik Dahl of the Naval Postgraduate School in Monterey, Calif., and the START program at the University of Maryland has compiled the most detailed list of attempted terrorists attacks to date, spanning a period of 25 years, in his paper “The Plots That Failed: Intelligence Lessons Learned From Unsuccessful Terrorist Attacks Against the United States,” recently published in the academic journal Studies in Conflict and Terrorism.
“Everyone in American national security is amazed that we haven’t had another 9/11 within America since 9/11. A lot of credit has to go to both the Bush and now the Obama administrations for keeping the country a lot safer than anybody expected. That’s the good news,” Dahl tells me. “But the bad news is that we do see this continuing, steady drumbeat of smaller-scale plots and attempted terrorist attacks. So the threat is definitely not gone.”
And what does Dahl believe has most accounted for the extraordinary Homeland Security record of success to date? “When it comes to domestic attacks and securing the homeland, what works is really good, old-fashioned policing—law enforcement, tips from the public, police informants—and not so much spies overseas or satellites run by three-letter government agencies.”
Interestingly, while compiling his list, Dahl found that “about 75 percent of the plots are associated with radical Islamists and about 25 percent are from right-wing domestic, anti-government militia movements.” But for the purposes of marking the 9/11 anniversary, this list focuses solely on the Islamist terrorist plots against Americans at home or on military bases outside war zones overseas.
An additional point of consideration is the cooperation that Muslim Americans have given to police that has helped stop many terrorist plots to date. “Local law enforcement and FBI officials have very good relations with the mainstream Muslim communities in various parts of America,” attests Dahl.
In the absence of another major terrorist attack on U.S. soil, it can be too easy to ignore the heroic efforts that have saved countless American lives over the past decade we have been at war.
It can also be easy to ignore the trends that have emerged, even after the welcome death of Osama bin Laden and the Obama administration’s successful escalation against al Qaeda. “We’re seeing more of an effort to attack U.S. military targets within the U.S., such as the Fort Hood shooting,” Dahl says. “These domestic lone-wolf attacks are not likely to be able to cause the amount of damage that a carefully planned and executed international plot, such as an al Qaeda plot, can do. But they can kill a lot of people.”
We now know that Osama bin Laden had long hoped for a 10th anniversary attack; and the threat of a lone wolf attack may be at the heart of this latest credible threat officials are investigating. But America’s first line of defense will be especially vigilant on this anniversary of the day when Islamist terrorists declared war on the U.S.
Looking to the future, Dahl sees a need to remain focused on the threats we face, while working to achieve the right balance “between reporting on things, the ‘see something-say something’ approach on the one hand, and respecting civil liberties and the rights of individuals to go about their daily lives. We still haven’t figured out just where that balance is in America.” But in our democratic republic’s response to 9/11 and subsequent civic debates we come ever closer to finding the right balance.
The bad news is that we see this continuing, steady drumbeat of smaller-scale plots and attempted terrorist attacks.
After the attacks of 9/11, we swore that we would never forget. And so, among the memorials on this 10th anniversary that honors the victims and heroes we lost, it is also appropriate to remind ourselves of the need to remain vigilant. We honor the dead from that day by resolving to do all we can to stop future 9/11s.
First responders have a saying: “Hope for the best; prepare for the worst.” The civic resilience of the United States in the wake of the attacks of 9/11 is a testament to the power that free people have to overcome the forces of fear. We have been both lucky and good, and—as this rogues’ gallery of foiled terrorist plots reminds us—we all owe the broader counterterrorism community our thanks. America is the land of the free because we are the home of the brave.
