I don't think we've ever lived in such a dangerous time, on a range of different levels. We also live in an extremely exciting time with a multitude of opportunities for each and every one of us to engage our individual voices, to engage more effectively collectively, to tackle some of these issues that would have seemed beyond our reach just a few years ago.

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 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.

When my father began to work with President John. F.Kennedy, we moved to Washington, D.C. I was fortunate in my pre-adolescent years, as my social and political consciousness was developing, to live at the epicentre of that dynamic, idealistic, and inspiring moment in U.S. political history, with its ethos of personal and civic responsibility, summed up so succinctly in his exhortation: "Ask not what your country can do for you, but ask what you can do for your country."
