Although the death of Osama bin Laden on May 2, 2011, marked a triumphant day for the United States, the death of the charismatic leader of al-Qaeda did not mark the end of his terrorist organization.

Al-Qaeda continues to operate globally and still poses a severe threat to international and homeland security. Of particular interest to the United States is how al-Qaeda has exploited the political weakness and instability in the horn of Africa and the Arabian Peninsula:

Terrorist organizations need several things to be effective: an ideological platform, financial wherewithal, and physical space to train, equip, and plan operations. Counter-terrorism efforts focus on denying both financial support and physical space, while simultaneously attempting to undermine terrorist ideology.

During the past two decades, the shifting organizational structure within terrorist organizations, from large units to smaller more autonomous cells, has made their identification and targeting more difficult. These cells and their networks operate globally. Therefore, counter-terrorism efforts must be global.

Effectively targeting cells requires an understanding of what conditions a terrorist organization is likely to prosper in. These conditions include corruption, lack of economic prosperity, and a weak central government. Corruption, whether sanctioned culturally or governmentally, allows terrorists to pay for operational freedom. Lack of economic prosperity — generally coupled with a lack of education — allows terrorists to exploit the local population. Finally, a weak central government is an invitation for terrorist organizations to take advantage of and gain a foothold within a country.

While these conditions are not required for terrorist groups or cells to exist — after all, many terrorist cells operate within stable, prosperous countries — they allow for a better incubation, and thus increased effectiveness, of a terrorist organization.

Of particular concern to us will be Somalia and Yemen.

Al-Qaeda’s connection to Yemen, through the bin Laden family, began before the terrorist organization even took shape: The bin Laden family hails from southern Yemen. It moved to Saudi Arabia in the 20th century, where the family made its fortune in construction.
