[Ed. – Recall that, although the U.S. withdrew from the JCPOA and Iran said she would no longer be limited by it, the centrifuge activity is prohibited by UNSCR 2331, which has not been rescinded. So Iran is technically in breach of an instrument deemed to have force. Of course, the UNSC will do nothing about it, starting with the U.S.]
Iran on Saturday started up advanced uranium enrichment centrifuges in breach of its commitments under the Joint Comprehensive Plan of Action (JCPOA) to curb its nuclear program.
The new move is a direct challenge to the US, after talks began last week aimed at reviving the 2015 nuclear deal. Washington said it had offered “very serious” ideas on rescuing the agreement, which collapsed in 2018 when the US withdrew, but was waiting for Tehran to reciprocate.
Tehran’s response came on Saturday, when President Hassan Rouhani inaugurated a cascade of 164 IR-6 centrifuges for producing enriched uranium, as well as two test cascades of 30 IR-5 and 30 IR-6S devices at the Natanz uranium enrichment plant, in a ceremony broadcast by state television.
