Change is never easy, but always possible.

I think that people are born with a certain makeup, and that we're all children of God.

One of the things that I've learned, and I think we've all learned, is that we are not going to get the kind of decisive, permanent victories in this fight against terrorism that we would get from fighting another country. We're not going to get that MacArthur/Emperor moment, because by definition, even after decimating Al Qaeda in the Fata, even after taking out [Osama] bin Laden there's still people there who have both the interest and the capacity if we don't maintain vigilance to strike against the United States.

One of the things I've learned about being president is that we'll work on issues for long periods of time, sometimes in obscurity.

Today we continue a never ending journey to bridge the meaning of those words with the realities of our time.

But do I think that our actions in anyway violate the War Powers Resolution, the answer is no.

Americans coming home, an Iran that has rolled back its nuclear program and accepted unprecedented monitoring of the program -these things are a reminder of what we can achieve when we lead with strength and with wisdom, with courage and resolve and patience. America can do and has done big things when we work together.
