[Our troops in Iraq and Afganistan] does give us the ability to make sure that we are strengthening those folk who are interested in building up their countries rather than destroying them, and doing so in a way that is sustainable and doesn't put a constant burden on the amazing men and women that we've got in uniform.

Part of the reason that our politics seems so tough right now and facts and science and argument does not seem to be winning the day all the time is because we're hardwired not to always think clearly when we're scared. And the country's scared.

The fear among economists across the political spectrum that was - was that we were rapidly plummeting towards a second Great Depression. So, in the weeks and months that followed, we undertook a series of difficult steps to prevent that outcome. And we were forced to take those steps largely without the help of an opposition party, which, unfortunately, after having presided over the decision-making that had led to the crisis, decided to hand it over to others to solve.

When we helped prevent the massacre of civilians trapped on a distant mountain, here's what one of them said: "We owe our American friends our lives. Our children will always remember that there was someone who felt our struggle and made a long journey to protect innocent people." That is the difference we make in the world.

I believe in evolution, scientific inquiry, and global warming; I believe in free speech, whether politically correct or politically incorrect, and I am suspicious of using government to impose anybody's religious beliefs -including my own- on nonbelievers.

Our unalienable right to life and liberty and the pursuit of happiness, those rights were stripped from college kids in Blackburg and Santa Barbara, and from high schoolers at Columbine. And, and from first graders in Newtown, first graders.

There's no one who I believe has ever captured the soul of America more profoundly than Abraham Lincoln has.
