"In light of recent developments, some have suggested that now is not the right time to pursue peace. I disagree," he said, according to remarks prepared for delivery.
"I believe that now is precisely the right time to begin these negotiations, for a number of reasons."

"Today, Palestinians and Israelis each understand that helping the other to realise their aspirations is the key to realising their own - and both require an independent, democratic, viable Palestinian state.
"Such a state will provide Palestinians with the chance to lead lives of freedom, purpose and dignity, and such a state will help provide Israelis with something they have been seeking for generations - to live in peace with their neighbours." © 2007 Australian Broadcasting Corporation
