Iran’s decision to resume 20 percent uranium enrichment at its Fordow underground nuclear facility is likely to exacerbate already heightened U.S.-Iran tensions and poses a new hurdle to the incoming Biden administration’s hopes of reviving the moribund Iran nuclear deal.
Even with renewed tensions between the two countries, top Biden advisors said the incoming administration plans to reopen negotiations with Iran to curb its nuclear program. During the Trump administration, which pulled out of the Iran deal in 2018, Iran has resumed enrichment and gotten closer to being able to build a nuclear weapon—despite the Trump administration’s so-called “maximum pressure” strategy.
