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.

My dad was in the army. World War II. He got his college education from the army. After World War II he became an insurance salesman. Really, I didn't know my dad very well. He and my mother split up after the war. I was raised by my maternal grandmother and grandfather, and by my mother.

The accounting of the sacrifice is, more than anything else, the attitude toward war memorials in our time.

Many problems are so complex that even if we had the money to fix them, we wouldn't know how to do it. Fixing inner-city schools, reducing obesity, creating peace in the Middle East are just a few examples.

When we have done our best, we should wait the result in peace.
