There has been much commentary about the U.S. airstrike last weekend against three key nuclear sites deep inside Iran: Natanz, Fordow, and Isfahan. The attack—President Donald Trump’s boldest use of military force to date—was designed to stunt if not destroy Iran’s nuclear program and bring Iran back to the nuclear negotiating table in a much weaker position. As the dust settles over the American missile and bomb craters, questions continue to swirl about the effectiveness of the U.S. strikes and their impact on the region more broadly.
Operation Midnight Hammer was designed to destroy and degrade the key bottleneck in Iran’s nuclear program: its enrichment capacity, including its most advanced and large-scale centrifuge cascades. The lion’s share of Iran’s operational IR-6 centrifuges were believed to be housed in the three facilities struck by the United States last weekend. Iran’s near nine-hundred pound stockpile of 60 percent enriched Uranium, which can fit in the equivalence of the trunks of ten cars, remains unaccounted for. But this stockpile will be of little use for any Iranian nuclear weapons program in the near term if their enrichment capabilities were wiped out.
The battle damage assessment remains murky. Though Trump has repeatedly claimed the country’s nuclear program is “completely and totally obliterated,” comprehensive assessments of the damage take time. Neither the United States nor Israel has released a final assessment on the strikes’ consequences for the nuclear program. It’s still early days. Earlier this week, a preliminary classified report by the Defense Intelligence Agency (DIA), the Pentagon’s intelligence arm, estimated that the program had been delayed, albeit no more than six months. The director general of the International Atomic Energy Agency (IAEA) Rafael Grossi said that the centrifuges at Fordow are “no longer operational” and that there was “no escaping significant physical damage.” U.S. Chairman of the Joint Chiefs of Staff General Dan “Razin” Caine also emphasized that the United States had every reason to believe the strike was successful, while adding that the defense department had been preparing to destroy Fordow for more than a decade.
