GWEN IFILL:

We look at Rabin's legacy today, two decades later, with Dennis Ross, a longtime Middle East peace envoy, who served in Republican and Democratic administrations, Daoud Kuttab, a Palestinian journalist based in Amman, Jordan, and Ari Shavit, an Israeli columnist and author.

Ari Shavit, 20 years later, do you wonder whether things could have been different had Yitzhak Rabin not been killed?

ARI SHAVIT, Israeli columnist: Yes, I think there is a chance they would have been different, but I think that the romantic approach that we would have had a perfect ideal peace is somewhat flawed.

Let me say, first of all, as an Israeli, that Rabin's murder is a traumatic experience in our nation's history. In the way, it's a combination of the murder of Abe Lincoln, John Kennedy, and Martin Luther King.

Rabin wasn't a saint. He wasn't a sacred man. He had flaws. But he had an amazing — he wasn't only courageous, intelligent, and authentic person, but he really tried to end the conflict, the tragedy of the conflict. And he represented a benign, decent, benevolent Israel, something we all yearn for so much today.
