Martha Crenshaw has been researching terrorist organizations since the late 1960s. In the wake of the U.S. military’s successful mission against Osama bin Laden, she comments on what happens to Al Qaeda now, and the challenges that remain.

CISAC: What does the death of Osama bin Laden mean for the world?

Crenshaw: The killing of bin Laden brings closure to a pursuit that began well before the 9/11 attacks. The successful raid demonstrated American tenacity as well as a somewhat surprising ability to keep a secret over the past several months as American intelligence agencies zeroed in on bin Laden's fortified compound in Abbottabad. Although most of the world thought he was hiding in the mountainous and inaccessible border regions of Pakistan, sheltered by local tribes, he was actually centrally located in a city not too far from Islamabad. It is often said that terrorism cannot be deterred because terrorists have no return address, but it turned out that bin Laden did. After years of patient intelligence work the U.S. finally found it. 

CISAC: What happens to Al Qaeda now?

Crenshaw: There are differing opinions. One is that bin Laden is a unique figure and that there's no other leader of a terrorist organization that has the kind of aura he has. People who joined Al Qaeda swore personal allegiance to him. He had this kind of bearing, and they respected his personal piety. It's hard to replace a leader like that. At the same time, that part of the organization affiliated with bin Laden is still a major actor. A lot of attacks, like the London bombing, are traced back toward them. A lot of the failed and foiled attacks in the U.S. were traced back there, too, suggesting he played an operational role as well as an inspirational role.

On the other side, even if Al Qaeda disappeared, other affiliates like Al Qaeda in the Arabian Peninsula are still extremely dangerous and capable. They can trade on his reputation and inspire others to join. They might make demands for revenge. There are also those who could replace bin Laden, not so much as an inspirational leader but in terms of operations. The central organization's more visible second in command, Ayman Al-Zawahiri, is free although he will be under intense pressure. There is also a second-tier leadership whose abilities and appeal are largely unknown. Local affiliates such as Al Qaeda in the Arabian Peninsula have often overshadowed AQ central, and in fact AQAP is currently considered to be the most serious threat to US security. 

CISAC: It sounds like there is likely to be jockeying for power.

Crenshaw: There certainly will be. Will Zawahiri necessarily step into the No. 1 role now? Or will he be challenged? It's possible. You can kind of see how little we know and how hard it is for the U.S. to piece it together by how long it has taken to find bin Laden. The U.S. has been looking for him since 1998.

CISAC: Does that make things more or less dangerous?

Crenshaw: There's a theory that the more fragmentation you have, the higher the level of violence. The way you get more resources and support is to be more audacious than your rivals. You could have violence from one faction against another. There's also the idea that you attack your enemy to show how dangerous you really are. Nobody wants to be seen as weak, so they feel that they have to do what the other side is doing.

Twenty-eight rising leaders from emerging democracies around the world have been named to the 2011 class of Draper Hills Summer Fellows on Democracy and Development at CDDRL.

This group represents the seventh class of Draper Hills Summer Fellows and is composed of democracy activists, development practitioners, academics, policymakers, journalists, and entrepreneurs representing societies where democracy is most threatened. The finalists were selected from a competitive pool of over 200 applicants and represent a dynamic cohort of mid-career professionals who are committed to improving or establishing democratic governance, economic growth, and rule of law in their home countries.

The program is funded by generous support from Bill and Phyllis Draper and Ingrid von Mangoldt Hills.

Some interesting statistics to illustrate the diverse nature of this class are as follows; 50 are women, the average age is 37 years, almost half hold graduate degrees, and Africa and the Middle East represent the largest geographical proportion of the incoming class.

Together, the Draper Hills Summer Fellows are helping to accelerate social and political change by developing multiparty democracy in Ghana, fighting for minority rights in Nepal, promoting good governance in Zimbabwe, training political parties in Iraq, and advocating for constitutional reform in Venezuela.

This group will convene at Stanford University July 25-August 12, for a three-week intensive executive education program led by an interdisciplinary team of leading faculty affiliated with CDDRL. During this time, the Draper Hills Summer Fellows will hear from distinguished speakers, engage in peer learning, and meet with executives of leading Silicon Valley companies and non-profit organizations to share best practices and expand their professional networks.

This high-impact program helps to create a broader community of global activists and practitioners, intent on sharing experiences to bring positive change to some of the world's most troubled regions.
