In January, U.S. forces conducted two operations to stop vessels smuggling lethal aid from Iran to Yemen. The interdictions took place against a backdrop of ongoing Houthi missile and drone attacks against ships in the Red Sea, highlighting the role Iran has played in enabling the Houthis' assault on global commerce.
The advanced state of Iran's nuclear program has raised concerns that the country could become "the next North Korea." But the North Korean case also holds lessons that may assist the United States in its use of diplomacy, sanctions, and other tools to prevent Iran from building nuclear weapons or to contain it if it does.
How quickly could Iran get enough fissile material for a small nuclear arsenal? This timetable estimates how quickly Iran could amass enough weapons-grade uranium for five bombs. Once it has the enriched uranium, however, it could take at least several months to turn it into a working weapon.
Weapon Program Background Report
In recent years, Iran has developed and deployed centrifuge models that can enrich greater amounts of uranium with fewer machines relative to its original IR-1 design. This table sets out the number of installed and operational centrifuges at Iran's enrichment sites, as well as the capacity and primary materials of each centrifuge model.
