PREVIOUS APPEARANCES ON THE TIME 100: 1
PRO: More than a decade after leading a fact-finding mission focusing on the Arab-Israeli conflict, the respected diplomat has been drafted to help bring peace (or some semblance of peace) to the fractured region.
CON: Peace in the Middle East has always been a near impossible task, and growing anti-U.S. sentiment is only going to make it harder.
