Over the past two weeks, Israel has begun a diplomatic campaign to thwart a resolution to subject its nuclear facilities to international supervision. The resolution, which is being pushed by Egypt and other Arab and Muslim states, will come up for a vote at the International Atomic Energy Agency’s General Conference in mid-September.

A senior Foreign Ministry official said he feared the recent nuclear deal between Iran and the six powers will make it hard for Israel to defeat the resolution.

The resolution, titled “Israeli nuclear capabilities,” has been repeatedly proposed by Egypt in recent years. It condemns Israel, demands that it open its reported nuclear facilities to IAEA inspection, and calls for an international conference on making the Middle East a nuclear-weapons-free zone.

Unlike Security Council resolutions, this one wouldn’t be binding. But it could still cause Israel great diplomatic damage, focus international attention on Israel’s nuclear program and prompt further IAEA action.

A few months ago, Egypt and Iran proposed a similar resolution at the Nuclear Nonproliferation Treaty (NPT) review conference, but the United States, Britain and Canada blocked it after Egypt refused to soften the language.

Though Egypt is the IAEA resolution’s chief sponsor, Iran seems likely to join the move. Iranian Foreign Minister Mohammad Javad Zarif indicated as much by publishing an article in The Guardian titled, “Iran has signed a historic nuclear deal – now it’s Israel’s turn.”

Zarif wrote that Israel must be pressured to join the NPT and advance an international conference on a nuclear-weapons-free Middle East. Israel, he wrote, has “an undeclared nuclear arsenal and a declared disdain towards non-proliferation, notwithstanding its absurd and alarmist campaign against the Iranian nuclear deal.”

For the last three years, Israel has succeeding in mustering a majority against Egypt’s IAEA resolution, thanks partly to proposals for a direct regional security dialogue with Arab states under UN auspices. Egypt and various other countries rejected these proposals, but they earned Israel considerable international credit.

The campaign to thwart the latest resolution began two weeks ago, when the Foreign Ministry sent a cable to all Israeli embassies and consulates instructing them to urge their host governments to oppose it.

“The resolution is fundamentally biased and mistaken, aimed at diverting global attention from the real dangers of nuclear proliferation in this region,” the cable’s talking points said. “This move will further politicize the IAEA and undermine the trust necessary for any regional dialogue on this issue.”

Israel has also sent personal envoys to several countries it considers key to winning the vote. For instance, former Foreign Ministry director general Nissim Ben Shitrit went to Argentina about 10 days ago, on the assumption that if Argentina doesn’t back the Arab proposal, other Latin American countries would likely follow suit.

Senior Israeli officials are divided over how the Iranian deal will impact the IAEA debate. Some argue that following the Iran agreement, America and other leading countries won’t want to raise the pressure on Israel even further. But others fear that with the Iran deal done, the international focus will shift to Israel’s nuclear program. They also fear Israel will enjoy less American support than in the past, due to the severe tensions with Washington over the Iran deal.
