President Obama has made it clear that the United States is determined to prevent Iran from acquiring nuclear weapons.

I'm not ideological. I think sometimes when people are ideological, the world's a lot easier. Because it falls into either right or wrong, or black or white, or whatever. To me, I'm still trying to figure out a lot of things.

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.

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

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.

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.

Yes, war is hell. It is awful. It involves human beings killing other human beings, sometimes innocent civilians. That is why we despise war.
