The Israeli left is increasingly waking up to the disturbing reality that their country is surrounded by people with genocidal intent, and historian Benny Morris is a case in point: Running out of Solutions.

On an overcast afternoon in early April, unsmiling men with big guns and earpieces patrol the sidewalk in front of Israeli Prime Minister Benjamin Netanyahu’s private residence in the upscale Jerusalem neighborhood of Rehavia. A short walk up the road on Azza Street, Benny Morris sits outside a cafe, radiating despair. “Iran is building atomic weapons at least in part — maybe in large part — because it intends to use them. The people there are religious fanatics,” he says in a rapid staccato. “Israel is under existential threat, and that is how Israel’s military and political leaders must see the situation.” In a 2007 essay, Morris, a professor of history at Ben-Gurion University, imagined a “second holocaust”: nuclear-tipped Iranian missiles raining down on Haifa and Tel Aviv. “A million or more Israelis … will die immediately,” he predicted.

That is not the sort of language one expects from an icon of the left and an intellectual lodestar for supporters of the Palestinians. But Morris, 60, like much of the Israeli left, has grown ever more cynical about the prospects for a two-state solution and for peace. In his new book, One State, Two States: Resolving the Israel/Palestine Conflict, Morris argues that the Palestinian national movement has never in fact reconciled itself to Israel’s existence as a Jewish state. His shift from Oslo Accords optimist to embittered pessimist is emblematic of the disappointment and frustration that has ravaged the Israeli left since the second intifada. “Morris is a one-man microcosm of what many Israeli Jews of the Labor-Zionist strain have undergone in the past decade,” says David B. Green, opinion editor at Ha’aretz’s English edition. “They recognize that we’re not on the verge of peace, that this conflict may not be resolvable, and that they were naive to think that was the case.”
