In 1994, Shimon Peres won the Nobel Peace Prize together with Yitzhak Rabin and Yasser Arafat for the peace talks that produced the Oslo Accords. Peres participated in these talks as the Israeli Foreign Minister, under Prime Minister Rabin. During his career, he has represented five parties in the Knesset (Mapai, Rafi, the Alignment, Labour and Kadima), and has led two of them (the Alignment and Labour).
I'm guessing he sucks up to the Arabs.
