President Trump, presaging a potential dénouement within the ensuing 48 hours, intimated substantive advancements in the dialogue with Iran concerning its nuclear dossier, a sanguine assessment juxtaposed against the circumspect evaluation proffered by the Omani intermediary, who characterised the yields of the fifth Roman parley as "incremental, yet indecisive"; notwithstanding this divergence, Trump underscored the "palpable headway" realised during the weekend's deliberations, conducted under the auspices of the Omani Embassy in Rome and featuring Mideast Envoy Steve Witkoff and Michael Anton, the State Department’s policy planning director, as American plenipotentiaries, the crux of the negotiation being the attenuation of Iran's nuclear ambitions in return for a calibrated revocation of extant U.S. economic strictures.
