As we've seen, deploying large armies abroad won't always be our best offense. Countries typically don't want foreign soldiers in their cities and towns.

By the time President Obama took office, Guantanamo was viewed internationally as a symbol of a counterterrorism approach that flouted our laws and strayed from our values, undercutting the perceived legitimacy - and therefore the effectiveness - of our efforts.

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.

I think the rule should be that if we're going to take actions overseas that result in the deaths of people, the United States should take responsibility for that.

I think we do have to take off the gloves in some areas, but within balance, and at the right time and the right way, and for the right reason and with full understanding of what the consequences of that might be.

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.

I will not, nor will I ever, publicly divulge sensitive intelligence sources and methods. For when that happens, our national security is endangered and lives can be lost.

If a person is a U.S. citizen, and he is on the battlefield in Afghanistan or Iraq trying to attack our troops, he will face the full brunt of the U.S. military response.

In full accordance with the law - and in order to prevent terrorist attacks on the United States and to save American lives - the United States government conducts targeted strikes against specific al-Qa'ida terrorists, sometimes using remotely piloted aircraft, often referred to publicly as drones.

It's not that the system is broken, but clearly there are ways to improve the system, strengthen it, to make sure that we can put together the various bits and pieces of information in a way that allows us to stop every single terrorist out there.

Obviously, the death of Usama Bin Laden marked a strategic milestone in our effort to defeat al-Qa'ida. Unfortunately, Bin Laden's death, and the death and capture of many other al-Qa'ida leaders and operatives, does not mark the end of that terrorist organization or its efforts to attack the United States and other countries.

Our counterterrorism tools do not exist in a vacuum. They are stronger and more sustainable when the American people understand and support them. They are weaker and less sustainable when the American people do not.

Our democratic values also include - and our national security demands - open and transparent government. Some information obviously needs to be protected. And since his first days in office, President Obama has worked to strike the proper balance between the security the American people deserve and the openness our democratic society expects.

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. But President Obama has made it a priority to renew American leadership in the world, strengthening our alliances and deepening partnerships.

Simply stated, the need for accurate intelligence and prescient analysis from CIA has never been greater than it is in 2013 - or than it will be in the coming years.

Since taking office, President Obama has worked to restore a positive vision of American leadership in the world - leadership defined, not by the threats and dangers that we will oppose, but by the security, opportunity and dignity that America advances in partnership with people around the world.

Sometimes there are actions that we are forced to take, but there need to be boundaries beyond which we are going to recognize that we're not going to go because we still are Americans, and we are supposed to be representing something to people in this country and overseas.

Terrorism needs to be fought against and certainly delegitimized or attacked, but some of the underlying grievances that might in fact lead individuals astray to terrorism cannot be ignored.

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.

The CIA has acknowledged that it has detained about 100 terrorists since 9/11, and about a third of them have been subjected to what the CIA refers to as 'enhanced interrogation tactics,' and only a small proportion of those have in fact been subjected to the most serious types of enhanced procedures.
