This morning during a Senate hearing on the Iran nuclear deal, Secretary of State John Kerry tried to pour cold water on the notion that friends of Israel are obligated to oppose the pact. Citing a Washington Post op-ed titled “How the Iran deal is good for Israel, according to Israelis who know what they’re talking about,” Kerry treated the piece that cites the opinions of a few retired officials that agree with him as proof that his claim that the result of his two years of negotiating with Iran would benefit the Jewish state as well as the United States. A similar piece in the Forward by J.J. Goldberg quotes some of the same figures. Taken together, they seem to make a strong case that the pro-Israel community ought to either sit out the Iran deal fight in Congress or even support the agreement. But the two articles leave out a couple of important facts about Israeli opinion about the Iran deal. One is that most of those quoted are either disgruntled former officials who hold a grudge against Prime Minister Netanyahu for not keeping them in office, or ideological opponents of the man who has won three consecutive elections. The other is that while Netanyahu’s political foes in the Knesset are as sharply critical of the prime minister as the Obama administration, they have joined him in forming a united front against the Iran deal as a deadly threat to the country’s future. That’s a point that any American that claims to be a friend of Israel needs to consider before they consider backing the administration’s push for détente with the Islamist regime.

As Jeffrey Goldberg, who has been the administration’s unofficial mouthpiece on Israel issues and their dutiful amanuensis when it comes to smears of Netanyahu, noted in The Atlantic last week, the man that Washington desperately wanted to win the Knesset election in March has turned on Obama. Labor Party leader Isaac Herzog was the darling of the White House earlier this year as the administration moved heaven and Earth in a failed attempt to influence the Israeli electorate to reject Netanyahu’s bid for a third straight term as prime minister. As Goldberg wrote, Herzog’s line on the Iran negotiations last winter was that he trusted Obama to get a “good deal” with Tehran. But rather than continuing his effort to cozy up to the administration, Herzog now completely agrees with Netanyahu’s evaluation of the deal. As Goldberg wrote:

In a telephone call with me late last night, Herzog’s message was very different. The deal just finalized in Vienna, he said, “will unleash a lion from the cage, it will have a direct influence over the balance of power in our region, it’s going to affect our borders, and it will affect the safety of my children.”

Iran, he said, is an “empire of evil and hate that spreads terror across the region,” adding that, under the terms of the deal, Iran “will become a nuclear-threshold state in a decade or so.” Iran will take its post-sanctions windfall, he said, and use the funds to supply more rockets to Hezbollah in Lebanon, more ammunition to Hamas in Gaza, and “generally increase the worst type of activities that they’ve been doing.”

The other major figure in the Israeli opposition, Yair Lapid, the leader of the Yesh Atid Party has also chimed in with harsh criticism of the agreement with Iran. In fact, the administration has achieved something that is generally considered impossible: uniting the Zionist parties of the Knesset from right to left. Netanyahu, Lapid, and Herzog and the leaders of the other parties normally can’t agree on anything. But Obama and Kerry have brought them together to denounce a deal that all know makes their region more dangerous while also presenting an existential threat to Israel’s future.

As I noted earlier this week, there is nothing in the deal that will prevent Iran from using the vast windfall it gets from sanctions relief to help fund its terrorist auxiliaries and allies that face off against Israel. Both Hezbollah in Lebanon and Hamas in Gaza can expect to get a share of the flood of cash that President Obama is allowing Tehran. Kerry’s claims that such transfers won’t be allowed are absurd since even National Security Director Rice conceded, it will be their money.

Nor is anyone of stature in Israel’s political establishment on either side of the left-right divide buying the idea that the loose restrictions that will soon expire can do anything to stop an Iranian bomb. Like American critics of the Iran deal, they consider the administration’s arguments that there are no alternatives to their appeasement policy short of war to be a self-fulfilling prophecy. Having discarded all the enormous political and economic leverage it held over Iran in 2013, it is disingenuous, if not completely dishonest of Obama and Kerry to say that theirs is the best option. Having effectively spiked a the chances that tougher sanctions would bring Iran to its knees when they began bowing to Iranian dictates in the talks, their current claim that opponents are warmongers has no credibility.

Some Israelis, Lapid in particular, do criticize Netanyahu for his strident opposition to Obama’s Iran strategy over the last two years. Seeking to make political hay out of this catastrophe for Israel, they argue that if Netanyahu had been nicer to Obama or at least not criticized him publicly, the U.S. might not have signed such a horrible deal.

This is nonsense. Netanyahu may have made some tactical mistakes in the last few months, in particular his decision to address Congress in March. He gave a great speech but it did nothing to stop Obama and even served the administration’s interests by diverting attention away from their policies and allowing Democrats to rally ’round their “insulted” president. But President Obama has been determined to create a new détente with the Islamist regime since the day he entered office. In doing so, he has discarded every other U.S. interest in the talks including the need to stop Iranian support for terrorism, its anti-Semitism, its determination to destroy Israel, its quest for regional hegemony and its ballistic missile program, in order to get a deal at any price. Netanyahu had no chance to alter Obama’s course.

But Israel’s rare political unity on the issue should influence Americans who care about the Jewish state. If Netanyahu, Herzog and Lapid all agree that the deal is terrible, no member of the Congress or the Senate who wishes to present themselves as friends of Israel should be allowed to get away with claiming that he knows better than these leaders, no matter how many disgruntled retired Israeli spooks can be assembled to contradict them.

Efforts by the administration’s left-wing allies to undermine the unity of the pro-Israel community should be dismissed out of hand. The deal is a clear and present danger to Israel’s future and should be treated as a litmus test of backing for Israel as well as reliability on U.S. security. All members of the House and Senate — especially those, like Senator Chuck Schumer that have staked their reputations as being guardians of Israel’s security — should be put on notice that they must choose between loyalty to Obama and what is right.
