In October, shortly before stepping down, Secretary of Energy Rick Perry announced that talks over providing Riyadh with American assistance in developing its civilian nuclear capabilities had reached an impasse over Saudi reluctance to pledge not to enrich uranium. Once a country can enrich uranium itself, it can produce not only the low-enriched fuel used for civilian purposes but also the high-enriched form necessary for nuclear weapons. For decades, the American-led nonproliferation regime has allowed nations to purchase the former while forbidding them to enrich it themselves. But the Obama administration’s recognition of an Iranian “right to enrich” has overturned that standard. Yoel Guzansky notes the consequences:

The kingdom’s interest in nuclearization is nothing new, [but] in March 2018, [the] Saudi crown prince Mohammad bin Salman said publicly—and explicitly—for the first time that if Iran acquired military nuclear capabilities, the Saudis would follow suit without delay.

It’s possible that a dangerous nuclear loop has been established between Iran and its neighbors: Iran’s nuclear efforts are motivating the states that feel threatened by Iran to nuclearize, and attempts by Saudi Arabia—and Turkey—to nuclearize do nothing to convince Iran to stop its nuclear program. At some point, Iran and its neighbors’ progress on nuclear infrastructure and knowledge could pass the point of no return.

Israel has an interest in preventing even Arab countries with which it cooperates, whether openly or in secret, from nuclearizing. This is because of the concern over a regional dynamic of nuclearization, which could push Iran to step up its own nuclear work; concern over dissemination of nuclear information; and concerns about a future change to the alignment of regional players or changes to friendly nations—for example, if a regime were to fall.

This week, there have been numerous unconfirmed reports about the fate of Esmail Qaani, who is the head of the Quds Force, the expeditionary arm of Iran’s Revolutionary Guards. Benny Avni writes:

On Thursday, Sky News Arabic reported that Mr. Qaani was rushed to a hospital after suffering a heart attack. He became [the Quds Force] commander in 2020, after an American drone strike killed his predecessor, Qassem Suleimani. The unit oversees the Islamic Republic’s various Mideast proxies, as well as the exporting of the Iranian revolution to the region and beyond.

The Sky News report attempts to put to rest earlier claims that Mr. Qaani was killed at Beirut. It follows several reports asserting he has been arrested and interrogated at Tehran over suspicion that he, or a top lieutenant, leaked information to Israel. Five days ago, the Arabic-language al-Arabiya network reported that Mr. Qaani “is under surveillance and isolation, following the Israeli assassinations of prominent Iranian leaders.”

Iranians are desperately scrambling to plug possible leaks that gave Israel precise intelligence to conduct pinpoint strikes against Hizballah commanders. . . . “I find it hard to believe that Qaani was compromised,” an Iran watcher at Tel Aviv University’s Institute for National Security Studies, Beni Sabti, tells the Sun. Perhaps one or more of [Qaani’s] top aides have been recruited by Israel, he says, adding that “psychological warfare” could well be stoking the rumor mill.

If so, prominent Iranians seem to be exacerbating the internal turmoil by alleging that the country’s security apparatus has been infiltrated.
