Arriving in Washington, D.C., Joshua walks along Pennsylvania Avenue with a cool detachment that sets him apart from the bustling crowds. Under ordinary circumstances, he would seem wrapped in his own thoughts.

This is the most difficult mission Joshua has undertaken--a plan to unite Arab and Jewish Americans and to work with them to resolve the problems of the Middle East.
