Reality has a way of asserting itself.

One of the things I've learned about being president is that we'll work on issues for long periods of time, sometimes in obscurity.

FDR, JFK, LBJ [all Democratic presidents ] we have a pretty long list of presidents who maybe were not entirely forthcoming with intelligence information before they went to war, so I'd be cautious against making legal cases against the administration.

What I consistently say to young people - I say it in the United States, but I'll say it here in Germany and across Europe: Do not take for granted our systems of government and our way of life. I think there is a tendency, because we have lived in an era that has been largely stable and peaceful, at least in advanced countries, where living standards have generally gone up, there is a tendency I think to assume that that's always the case.

If we can’t puncture some of the mythology around austerity, politics or tax cuts or the mythology that’s been built up around the Reagan revolution, where somehow people genuinely think that he slashed government and slashed the deficit and that the recovery was because of all these massive tax cuts, as opposed to a shift in interest-rate policy - if we can’t describe that effectively, then we’re doomed to keep on making more and more mistakes.

What is a danger is that we stay stuck in a new normal where unemployment rates stay high, people who have jobs see their incomes go up, businesses make big profits. But they're learned to do more with less, and so they don't hire.

The next phase and this is part of what I'm interested in doing after I get out of the presidency is to make sure that I'm working with that next generation so that they understand you can't just rely on inspiration. There's a little perspiration involved in bringing about change too. That you have to be organized, that you have to vote even when it's not exciting.
