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.

If we have Osama bin Laden in our sights and the Pakistani government is unable or unwilling to take them out, then, I think that we have to act and we will take them out. We will kill bin Laden. We will crush al Qaeda. That has to be our biggest national security priority.

As I travel around the world, it's fascinating; European leaders, Asian leaders, they all say to me, America is actually poised to be the world leader for another century - if we can fix some of this political dysfunction. ... We've got a lot of national security challenges, but if we get our economy together, and if we can get our political system to work well, I am really confident about our future.

I hope we can all agree that, instead of continuing to subsidize yesterday's energy sources. We need to invest in tomorrow's.

it’s important to make sure that we’re talking with each other in a way that heals, not in a way that wounds." - Barack Obama, 44th U.S. President
