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.

When I came into office, the world was divided. Iran was resurgent. Iran is at its weakest point, economically, strategically, militarily, then since - then in many years. And we are going to continue to keep the pressure on to make sure that they do not get a nuclear weapon. That's in America's national interest and that will be the case so long as I'm president.

I always believe that ultimately, if people are paying attention, then we get good government and good leadership. And when we get lazy, as a democracy and civically start taking shortcuts, then it results in bad government and politics.

Here in the United States, hopefully, what we're building are not just pyramids, are not icons to one pharaoh. What we're building is a culture and a way of living together that we can look back on and say, [This] was good, was inclusive, was kind, was innovative, was able to fulfill the dreams of as many people as possible.

I was pretty realistic to people about what we could get done, and the situation we were in, and trying to tamp down expectations. If you listen to my stump speeches, if you listen to what I said at Grant Park, I kept on saying, "Look, this is not just about me, this is not going to happen in one year, or one term, or even one presidency." And we tried to layer into everything we were saying a sense of hope, but also realism.

Tonight, I can report to the American people and to the world that the United States has conducted an operation that killed Osama bin Laden, the leader of al Qaeda, and a terrorist who's responsible for the murder of thousands of innocent men, women, and children.

All across the world, ...increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.
