Growing up in Israel, how can I not be an optimist? When you remember what Israel was 50 years ago and you see Israel now, one of the most successful countries in the world, stable, democratic, with an enormously stable economy despite everything that has happened in the global economy in the last few years, how can I not be an optimist?

There is nowhere I encounter greater understanding for Israel's existential issues than in the Oval Office.

The military operation in Lebanon was the most successful military operation in recent Israeli history. Many in Israel don't recognise that.

From the end of 2006 until the end of 2008 I think I met with Abu Mazen more often than any Israeli leader has ever met any Arab leader. I met him more than 35 times. They were intense, serious negotiations.

Food is kind of my entry card into everything. Food kind of opens the doors... because food is peace. It's good; it's positive.

When I arrived in America, I experienced serious culture shock. For someone with a religious upbringing, the 1960s were an extremely difficult time.

From infancy, I had been accustomed to hear pro and con discussions of slavery and the American Civil War. Although the British government finally decided not to recognise the Confederacy, public opinion in England was sharply divided on the questions both of slavery and of secession.
