(JTA) — World leaders encouraged Israel and the Palestinians to move the peace process forward in the opening events of Israel’s Presidential Conference.

The conference, dubbed “Facing Tomorrow,” is a gathering of world leaders, celebrities and leading thinkers hosted by Israeli President Shimon Peres in Jerusalem. The conference began on Tuesday with a celebration of Peres’s upcoming 90th birthday, where Peres issued his familiar call for Israel to push toward a two-state solution.

“The yesterday between us and the Palestinians is full of sadness,” he said. “I believe that the Israel of tomorrow and the Palestine of tomorrow can offer our children a ray of hope. The advancement of peace will complete the march of Israel towards the fulfillment of its founding vision.”

Peace took center-stage again on Wednesday morning, where Peres conferred Israel’s Presidential Medal of Distinction – the nation’s highest honor – on former United States President Bill Clinton. Clinton, who worked closely with Peres on Israeli-Palestinian negotiations in the 1990s, also stressed the need for peace in his acceptance speech.

“There are no perfect solutions to the Israel-Palestine conflict,” he said, adding that “Somebody else’s idiotic, negative, crazy behavior should not” lead to a similarly negative response by Israel.

The conference will continue through Thursday.
