US Secretary of State Rubio called for direct negotiations between the US and Iran during an interview with US media on the 22nd local time, and stated that the US is prepared to engage in dialogue with Iran on the 23rd. Rubio reiterated that Iran is allowed to have a civilian nuclear program but is not permitted to conduct uranium enrichment. Rubio indicated that Iran had rejected the US proposal and disappeared for 10 days before the US launched military action against it. Despite Iran's continuous efforts to send messages to its interlocutors, it did not even engage in direct talks with the US.
