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.

I think there are many experts who say, in fact, the most powerful nations on earth are more vulnerable today than the weaker nations because they're the targets of so many of these groups that are trying to steal, to buy, to build nuclear weapons.

For all its considerable merits and inspirational principles, the American system is based upon a continuous uninterrupted process of election campaigns, stretching out year after year. Lost in the perpetual scramble is any long-term vision.

I spent the first years working in Jordan trying to learn as much as I could about what was taking place in the country, about where there were gaps in the development process that needed attention.

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.

All depend upon the engagement of as many people as possible on all levels, from civil society to national leaders, to advocate for the kind of national and international commitments, legislation, and public/ private partnerships that can make the difference.

What keeps me awake at night is just, Am I making the best use of the time that remains for me, to both be as good an example as I can in my own daily life, and as compelling as possible a voice for the ways in which we can all work together to tackle these issues.
