I have somehow, continued to miss Oktoberfest so that's probably something that is better for me to do as a former president rather than as president, I'll have more fun.

There are problems that just end up being really hard and by definition the only problems that come to my desk are the ones that nobody else can solve.

I want people around the world to hear me. To all those who would do us harm, no act of terror will go unpunished. It will not dim the light of the values that we proudly present to the rest of the world. No act of violence shakes the resolve of the United States of America.

I think since the systematic emergence of terrorism and the assassination attempts, everything has tightened. My hope is that it loosens back up once I leave.

The good news is that the Paris Agreement is not just a bilateral agreement between the United States and some other country. You have 200 countries who came together. It's an international agreement.

What is true, though, is now we've got a bunch of videos that whatever side of the issue you're on, raises the temperature on these issues and makes people really focused .

Part of what we have to do a better job of, if our democracy is to function in a complicated diverse society like this, is to teach our kids enough critical thinking to be able to sort out what is true and what is false, what is contestable and what is incontestable. And we seem to have trouble with that. And our political system doesn't help.
