On Nov. 4, 2022, just after the current far-right Israeli government coalition won election, I wrote a column with this headline: “The Israel We Knew Is Gone.” It was meant to be a warning flare about just how radical this coalition is. Many people disagreed. I believe events have proved them wrong — and the situation is now even worse: The Israel we knew is gone, and today’s Israel is in existential danger.

Israel is up against a regional superpower, Iran, that has managed to put Israel into a vice grip, using its allies and proxies: Hamas, Hezbollah, the Houthis and Shiite militias in Iraq. Right now, Israel has no military or diplomatic answer. Worse, it faces the prospect of a war on three fronts — Gaza, Lebanon and the West Bank — but with a dangerous new twist: Hezbollah in Lebanon, unlike Hamas, is armed with precision missiles that could destroy vast swaths of Israel’s infrastructure, from its airports to its seaports to its university campuses to its military bases to its power plants.

But Israel is led by a prime minister, Benjamin Netanyahu, who has to stay in power to avoid potentially being sent to prison on corruption charges. To do so, he sold his soul to form a government with far-right Jewish extremists who insist that Israel must fight in Gaza until it has killed every last Hamasnik — “total victory” — and who reject any partnership with the Palestinian Authority (which has accepted the Oslo peace accords) in governing a post-Hamas Gaza, because they want Israeli control over all the territory between the Jordan River and the Mediterranean Sea, including Gaza.

And now, Netanyahu’s emergency war cabinet has fallen apart over his lack of a plan for ending the war and safely withdrawing from Gaza, and the extremists in his government coalition are eyeing their next moves for power.

They have done so much damage already, and yet not President Biden, the pro-Israel lobby AIPAC, nor many in Congress have come to terms with just how radical this government is.

Indeed, House Speaker Mike Johnson and his fellow G.O.P. mischief makers decided to reward Netanyahu with the high honor of speaking to a joint meeting of Congress on July 24. Pushed into a corner, the top Democrats in the Senate and the House signed on to the invitation, but the unstated goal of this Republican exercise is to divide Democrats and provoke shouted insults from their most progressive representatives that would alienate American Jewish voters and donors and turn them toward Donald Trump.
