I pretty much always feel gratitude. I thank God throughout the day.

We came together [with King Hussein of Jordan] because of a shared sense of idealism, of the value of service to a community far greater than ourselves, and the conviction that each and everyone of us can meaningfully contribute to solving even the most seemingly intractable problems.

I did feel a sense of duty. I felt that it could be a great asset to the future of Jordan, and those continuing the process of building the country, to concentrate on that humanitarian, peace-building legacy.

Everyone I knew, including my new friends in Jordan, expressed horror at the realities of the Holocaust. But they resented, as I was growing to, how Arabs were cast as the aggressors in the dispute between Israel and the Arab countries, when it was their land that had been seized to resolve a European political problem.

King Hussein of Jordan dedicated his life - I witnessed it in his sleeping as well as waking hours - to trying to break through the impasses keeping people apart. He understood that the security and prosperity of any one of us in this world depends on the security and prosperity enjoyed by others. As Martin Luther King said, "Injustice anywhere is a threat to justice everywhere." In the Middle East, nothing could be more true.

King Hussein never lost his faith, no matter how difficult and unbearable and cruel the circumstances could be. I always remember that. It helps me get through everything. It's a way of trying to keep that positive spirit alive for as many people as we can touch. I think that's good for the world.

I have witnessed firsthand the anguish of this humanitarian tragedy - in Palestine, Iraq, Syria, Pakistan, and other conflict and post-conflict zones. The destruction of lives and hopes, the emotional trauma, and the economic, social, and political marginalization of the displaced, the human insecurity, with real and potentially devastating consequences over generations, in ever-widening arenas of conflict. We can and must ensure the human rights of the displaced. That begins by making their voices heard.
