Iran could make enough material for one nuclear bomb in ‘about 12 days,’ a top US Defense Department official warned on Tuesday, a dramatic fall from the estimated one year it would have taken while the 2015 Iran nuclear deal was in effect.

Under Secretary of Defense for Policy Colin Kahl made the comment to a House of Representatives hearing when asked why US President Joe Biden’s administration had sought to revive the the Joint Comprehensive Plan of Action (JCPOA) deal.

‘Because Iran’s nuclear progress since we left the JCPOA has been remarkable. Back in 2018, when the previous administration decided to leave the JCPOA it would have taken Iran about 12 months to produce one bomb’s worth of fissile material.
