John O. Brennan

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

"Where terrorists offer injustice, disorder and destruction, the United States and its allies stand for freedom, fairness, equality, hope, and opportunity."

"While the intelligence profession oftentimes demands secrecy, it is critically important that there be a full and open discourse on intelligence matters with the appropriate elected representatives of the American people."

"I do not - I never believed it's better to kill a terrorist than to detain him. We want to detain as many terrorists as possible so we can elicit the intelligence from them in the appropriate manner so that we can disrupt follow-on terrorist attacks."

"The actions that we take on the counterterrorism front, again, are to take actions against individuals where we believe that the intelligence base is so strong and the nature of the threat is so grave and serious, as well as imminent, that we have no recourse except to take this action that may involve a lethal strike."

"We are in this business, whether it be intelligence or the government, to protect freedom, democracy and liberty, not to violate that."
