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.

I think there's something very dark in the South African psyche. I think we live a lot of the time in a state of a very low-grade civil war; the levels of violence in South Africa are extremely high. In a way, the civil war that never happened is being played out in a covert way, so we live with a lot of very ugly things.

This is not Johnson's war. This is America's war. If I drop dead tomorrow, this war will still be with you.

Growing up during the Cold War, I remember the seemingly imminent threat of nuclear war. In primary school we were taught to 'duck-and-cover' for protection. But even as children hiding under wooden desks, we recognized the inadequacies of this strategy.

Only by addressing the root causes of conflict and disputes can we hope to find lasting peace in a just and equitable world.
