This is not some distant problem of the future. This is a problem that is affecting Americans right now. Whether it means increased flooding, greater vulnerability to drought, more severe wildfires - all these things are having an impact on Americans as we speak.
If we're not there making the argument then the cultural gulf that Republicans try to exploit saying, "Ah, these city slickers: they're all looking down on you, they don't care about you. They're just trying to help out their various special interest constituencies," that argument ends up being successful.
Since taking office, I've made it clear that the United States was prepared to begin a new chapter of engagement with the Islamic Republic of Iran. We offered the Iranian government a clear choice. It could fulfill its international obligations and realize greater security, deeper economic and political integration with the world, and a better future for all Iranians. Or it could continue to flout its responsibilities and face even more pressure and isolation.
For the sake of our economy, our security, and the future of our planet, I will set a clear goal as President: in ten years, we will finally end our dependence on oil from the Middle East.
We learn from our mistakes, we do some reflection, we lick our wounds, we brush ourselves off - then we go forward, with the presumption of good faith in our fellow citizens.
If condoms and potentially microbicides can prevent millions of deaths [from AIDS], they should be made more widely available. I know that there are those who, out of sincere religious conviction, oppose such measures. And with these folks, I must respectfully but unequivocally disagree.
I think it's very important to remember that so much of the work that gets done between countries is not done at the level of presidents, but is done within various agencies, whether it's law enforcement or economic ministries. And when they establish relationships and systems of communications and shared projects and shared visions, those structures continue even after any particular president is gone. It builds trust and understanding between countries that are critically important.
From the first moment a woman dared to speak that hope - dared to believe that the American Dream was meant for her too - ordinary women have taken on extraordinary odds to give their daughters the chance for something else; for a life more equal, more free, and filled with more opportunity than they ever had. In so many ways we have succeeded, but in so many areas we have much work left to do.
We [USA] don't have diplomatic leverage to eliminate every vestige of a peaceful nuclear program in Iran. What we do have the leverage to do is to make sure that they don't have a weapon.
We have come from a time of the large-scale, planned, Al Qaeda-style attacks, to the encouragement of lone wolves: Fort Hood, Chattanooga. To the encouragement of people to act on their own.
I began feeling the way I imagine an actor or athlete must feel when, after years of commitment to a particular dream...he realizes that he's gone just about as far as talent or fortune will take him. The dream will not happen, and he now faces the choice of accepting this fact like a grownup and moving on to more sensible pursuits, or refusing the truth and ending up bitter, quarrelsome, and slightly pathetic.
I was never great, but I was a good [basketball] player, and I could play seriously. Now I'm like one of these old guys who's running around, and the guys I play with, who are all a lot younger, they sort of pity me and sympathize with me. They tolerate me, but we all know that I'm the weak link on the court. And I don't like being the weak link.
The president does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation. As commander in chief, the president does have a duty to protect and defend the United States. In instances of self-defense, the president would be within his constitutional authority to act before advising Congress or seeking its consent.
