Yesterday, France, Germany, and Britain moved to renew a UN embargo on Tehran’s import and export of missiles and missile technology, which was set to expire in October. Richard Goldberg, writing before the decision was made, explains the importance of this step:

Over the last year, Iran has transferred hundreds of armed drones to Russia for use inside Ukraine with thousands more planned. These drones have inflicted enormous damage and terrorized civilian populations. Russia is reportedly now domestically producing Iranian drones as well. When the missile embargo expires, Iran may consider transferring short-range ballistic missiles, too.

Ukrainian leaders may not believe these UN restrictions matter much, but they do. Believe it or not, Russian and Iranian propaganda rely heavily on international law to claim legitimacy in their illicit conduct.

Russia and Iran seek to chisel away at longstanding international norms of conduct and replace them with new ones that legitimize otherwise illicit conduct. They aim to establish a new accepted reality in which the independence of smaller states takes a back seat to their imperial ambitions. In this respect, they are not only waging a war against Ukraine on the ground and in the skies; they are waging political warfare, too. Allowing the UN missile embargo to expire is a victory for Moscow and Tehran, plain and simple. Keeping it and restoring the conventional arms embargo, too, would be a big win for Ukraine.

The European powers, however, decided not to reinstate sanctions on the Iranian nuclear program—which, Goldberg goes on to argue, is a mistake.

The Mossad’s heist of a vast Iranian nuclear archive in 2018 provided abundant evidence that Tehran was not adhering to its commitments; it also provided an enormous amount of actionable intelligence. Two years later, Israel responded to international inspectors’ condemnation of the Islamic Republic’s violations by using this intelligence to launch a spectacular campaign of sabotage—a campaign that is the subject of Target Tehran, by Yonah Jeremy Bob and Ilan Evyatar. David Adesnik writes:

The question that remains open at the conclusion of Target Tehran is whether the Mossad’s tactical wizardry adds up to strategic success in the shadow war with Iran. The authors give a very respectful hearing to skeptics—such as the former Mossad director Tamir Pardo—who believe the country should have embraced the 2015 nuclear deal with Iran. Bob and Evyatar reject that position, arguing that covert action has proven itself the best way to slow down the nuclear program. They acknowledge, however, that the clerical regime remains fully determined to reach the nuclear threshold. “The Mossad’s secret war, in other words, is not over. Indeed, it may never end,” they write.

Which brings us back to Joe Biden. The clerical regime was headed over a financial cliff when Biden took office, thanks to the reimposition of sanctions after Washington withdrew from the nuclear deal. The billions flowing into Iran on Biden’s watch have made it that much easier for the regime to rebuild whatever Mossad destroys in addition to weathering nationwide protests on behalf of women, life, and freedom. Until Washington and Jerusalem get on the same page—and stay there—Tehran’s nuclear ambitions will remain an affordable luxury for a dictatorship at war with its citizens.
