Al-Qa'ida does not follow a traditional command structure, wear uniforms, carry its arms openly, or mass its troops at the borders of the nations it attacks. Nonetheless, it possesses the demonstrated capability to strike with little notice and cause significant civilian or military casualties.

When we uphold the rule of law, our counterterrorism tools are more likely to withstand the scrutiny of our courts, our allies, and the American people.

As a matter of international law, the United States is in an armed conflict with al-Qaida, the Taliban, and associated forces, in response to the 9/11 attacks, and we may also use force consistent with our inherent right of national self-defense.

You always, I think, debate with yourself about whether or not you made the right decision. And you have to then give the person that you’re working for - in my instance, the president - your best judgment based on your understanding of the facts, but also the calculus you use to make a determination about what’s the best way to go forward.

President Obama is determined that our foreign and national security policies not play into al-Qa'ida's strategy or its warped ideology. Al-Qa'ida seeks to terrorize us into retreating from the world stage.

I want to be very clear - whenever it is possible to capture a suspected terrorist, it is the unqualified preference of the Administration to take custody of that individual so we can obtain information that is vital to the safety and security of the American people.

Poverty does not cause violence and terrorism. Lack of education does not cause terrorism.
