Avigdor Liberman, head of the Yisrael Beiteinu party (on most issues, to the right of Likud), has quit the Netanyahu-led coalition government, leaving it with barely enough seats to remain in power. At fault for this sudden instability, argues Haviv Rettig Gur, is not the personality of either Liberman or Netanyahu, but the Israeli political system:

In the end, Netanyahu’s manipulative management style and Liberman’s peculiar brand of political tantrum are both symptoms of a larger malaise: the stark fact that no Israeli politician or party can actually win an Israeli election. Even after doing better at the ballot box than any ruling party in a decade, Netanyahu can still find his coalition brought down to an untenable one-seat majority by the political maneuvers of a single Avigdor Liberman. . . .

A political system cannot be built on the assumption that every one of its actors will always pursue the common good. Liberman’s withdrawal, with all the havoc it is wreaking to the right and to the elected prime minister, is probably the most strategically wise move open to him, given his party’s collapsing electoral standing. While his stated reasons for the move may be questionable, there is nothing immoral in Liberman’s decision to leave.

The real culprit is the architecture of Israel’s politics, which allows a single Liberman or [Jewish Home leader Naftali] Bennett or [Shas leader] Aryeh Deri to topple a prime minister who—by any measure—is the nation’s preferred choice to run the executive branch.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
