Several undesirable consequences are becoming more likely.
This week, a set of Iran sanctions previously lifted under the Iran nuclear deal will snap back into effect as part of President Trump’s complete violation of the accord. Thus far, Iran has avoided rash action, instead seeking to secure concessions from Europe, Russia, and China that could reduce the sanctions’ impact. The cautious response may have lulled the Trump administration into thinking its approach is working, but several potential consequences loom on the horizon.
Renewed proliferation: Before the nuclear deal was signed in 2015, Iran’s heavy-water reactor at Arak was close to going online; it could have produced weapons-grade plutonium for several nuclear weapons per year. Moreover, the deeply buried Fordow facility was already being used to enrich uranium. However, under the nuclear accord Iran destroyed the core of the Arak reactor and agreed to redesign it with international partners so that it would not produce significant amounts of weapons-grade plutonium. Similarly, international partners in collaboration with the Atomic Energy Organization of Iran, or AEOI, are working to turn Fordow into a research-and-development facility, ensuring that Iran experiments with zinc or other benign materials instead of uranium at the site.
