I have made it a top priority for my administration to deepen cooperation with Israel across the whole spectrum of security issues - intelligence, military, technology.

Here in Europe some of the challenges have to do with structures that are so complicated. You've got Brussels, and you've got parliament, you've got councils and then you've got national governments. So people sometimes don't feel as if they know who's making decisions, and the more that we can bring people in and engage them, the better. Some of it is also cultural and social, people's sense of identity.

You don't know how it would have turned out if [kids] would grown up in Chicago instead, and a more normal environment.

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.

The challenge there is that ISIL doesn't have an air force, so the damage done there is not against ISIL, it's against the Syrian regime.

Part of what's changed in politics is social media and how people are receiving information.

For Democrats who are feeling completely discouraged, I've been trying to remind them, everybody remembers my Boston speech in 2004. They may not remember me showing up here in 2005 when John Kerry had lost a close election, Tom Daschle, the leader of the Senate, had been beaten in an upset. Ken Salazar and I were the only two Democrats that won nationally. Republicans controlled the Senate and the House, and two years later, Democrats were winning back Congress, and four years later I was President of the United States.
