I've said consistently that I always reserve the right, in conjunction with a broader international effort, to prevent genocide or any wholesale slaughter than might happen inside of Iraq or anyplace else.

The biggest threat that we face right now is not a nuclear missile coming over the skies. It's in a suitcase. This is why the issue of nuclear proliferation is so important. It is the - the biggest threat to the United States is a terrorist getting their hands on nuclear weapons.

Don't let your failures define you.

I face the world as it is and cannot stand idle in the face of threats to the American people. For make no mistake, evil does exist in the world.

And there’s been drift in Afghanistan over the last couple of years. That’s something that we intend to fix this.

America, we weaken our ties when we allow our political dialogue to become so corrosive that people of good character aren't even willing to enter into public service; so coarse with rancor that Americans with whom we disagree are seen not just as misguided but as malevolent. We weaken those ties when we define some of us as more American than others, when we write off the whole system as inevitably corrupt, and when we sit back and blame the leaders we elect without examining our own role in electing them.

...I believe deeply that we canot solve the challenges of your time unless we solve them together - unless we perfect our union by understanding that we may have differnt stories, but we hold common hopes; that we may not look the same and we may not have come from the same place, but we all want to move in the same direction - towards a better future for our children and our grandchildren. This belief comes from my unyielding faith in the decency and generosity of the American people.
