That is the title of book (which I have not read) by Omer Bartov. Dr. Bartov was born in Israel, raised in a Zionist household, served four years in the IDF, and currently teaches at Brown University where he is a professor of Holocaust and genocide studies.
Bartov says that Zionism had two faces: one that was liberating and pluralist; the other was ethnonationalist. Since the founding, he says, the emancipatory element has receded while the ethnonationalist element has become a “state ideology.”
A country founded as a refuge from intolerance has acquired the traits of an increasingly remorseless ethnonationalism. He is pessimistic about the future, noting that neither Israel nor the Palestinians have leadership capable of getting out of this morass.
I probably should read the book, but the Sunday Times review by Jennifer Szalai sounds absolutely depressing to anyone who hopes for peace in the Middle East.
