There is a prominent faction within the Israeli government that would just like to wipe out the Palestinians once and for all. From Chris Hedges at scheerpost.com:
When Jewish extremists, fanatic Zionists, religious zealots, ultranationalists and crypto-fascists in the apartheid state of Israel say they want to wipe Gaza off the face of the earth, believe them.

I covered the birth of Jewish fascism in Israel. I reported on the extremist Meir Kahane, who was barred from running for office and whose Kach Party was outlawed in 1994 and declared a terrorist organization by Israel and the United States. I attended political rallies held by Benjamin Netanyahu, who received lavish funding from rightwing Americans, when he ran against Yitzhak Rabin, who was negotiating a peace settlement with the Palestinians. Netanyahu’s supporters chanted “Death to Rabin.” They burned an effigy of Rabin dressed in a Nazi uniform. Netanyahu marched in front of a mock funeral for Rabin.
Prime Minister Rabin was assassinated on Nov. 4, 1995 by a Jewish fanatic. Rabin’s widow, Lehea, blamed Netanyahu and his supporters for her husband’s murder.
Netanyahu, who first became prime minister in 1996, has spent his political career nurturing Jewish extremists, including Avigdor Lieberman, Gideon Sa’ar, Naftali Bennett, and Ayelet Shaked. His father, Benzion — who worked as an assistant to the Zionist pioneer Vladimir Jabotinsky, who Benito Mussolini referred to as “a good fascist” — was a leader in the Herut Party that called on the Jewish state to seize all the land of historic Palestine. Many of those who formed the Herut Party carried out terrorist attacks during the 1948 war that established the state of Israel. Albert Einstein, Hannah Arendt, Sidney Hook and other Jewish intellectuals, described the Herut Party in a statement published in The New York Times as a “political party closely akin in its organization, methods, political philosophy and social appeal to Nazi and Fascist parties.”
