British Prime Minister Tony Blair opened a global conference on Palestinian reform on Tuesday, saying that reinvigorating the peace process to end the Israeli-Palestinian conflict was the world's most pressing political challenge. "There is probably no more pressing political challenge than to move this process forward," Blair said. "The significance of this issue and the Middle East peace process, or frankly lack of it over the past few years, the significance of what we are discussing is not confined to Israel, to Palestine or even to the Middle East. It is something that concerns all the countries represented her today."
