President Abbas, you've dedicated your life to advancing the Palestinian cause. Must this conflict continue for generations, or will we enable our children and our grandchildren to speak in years ahead of how we found a way to end it? That's what we should aim for, and that's what I believe we can achieve.

But so far, you know who's been violating the nuclear nonproliferation pact day and night? Those who signed it. Iran, Iraq, Libya and Iran violates it while calling for Israel's destruction and racing to develop atomic weapons to that end.

When I was mayor of New York, my views changed. I began as mayor of New York City thinking that I could reform the New York City school system. After two or three years, four years, I became an advocate of choice, of scholarships, and vouchers, and parental choice, because I thought that was the only way to really change the school system.

I don't want to go on stage with anger. And that's why I worked so hard to look within and change myself and evolve.

Network technology has irrevocably changed campaigning and elections. It has the potential to transform governance and the workings of our democracy for the better.
