Public life = onion

Headlines vs. Trendlines

    "Whenever you are tying to evaluate policy you should try to ask yourself: is there is a difference between story and the storyline. Always look for the story. Sometimes it's in the storyline and sometimes it's not. There is a difference between headlines and the trend lines. Typically for perfectly understandably reasons, bad news makes better news than good news. But sometimes the trend lines are better than headlines."

    Background music

    "For me personally always had a pretty simply purpose.

Are things coming together rather than being torn apart? To me all the rest is background music."

And the only thing is, you can't disagree with them or they'll kill you as we've seen."

    'Why this negotiation with Iran is so important'

    "I think you live in an exciting time. I think that is unlikely these ideological driven conflicts we're having now with non state actors will be fully resolved -- I hope and pray that we will leave behind a system that we can say with some confidence that we could keep really big, bad things from happening, that is why this negotiation with Iran is so important."
