U.S. and Iran Exchange Revised Terms via Mediators Amid Deepening Diplomatic Impasse

Tehran insists indirect diplomacy is a 'continuous process' despite Washington's dismissal of the latest peace proposal as insufficient.

Diplomatic back-channels between Washington and Tehran remain active through Pakistani mediators, though both sides indicate that a breakthrough is not imminent. Iranian Foreign Ministry spokesperson Esmail Baqaei confirmed that Tehran has responded to the latest U.S. peace proposal with its own 'positions.' However, U.S. officials told Axios that the updated proposal does not represent a meaningful improvement, noting that Iran has yet to engage in substantive negotiations regarding its nuclear program. President Trump is expected to convene his national security team in the Situation Room early this week to assess potential military options should diplomacy fail. While the President recently told the New York Post that Iran knows 'what’s going to be happening soon,' Iranian officials continue to emphasize the importance of maintaining a 'shaky ceasefire.' Despite the heightened rhetoric, no fresh large-scale military actions or new sanctions packages were confirmed in the last 24 hours. The strategic focus remains on the Strait of Hormuz, where the ongoing threat of disruption continues to influence global energy markets. While the U.S. maintains that it will not offer sanctions relief without reciprocal actions from Tehran, Iranian leadership maintains that the current U.S. demands remain 'excessive.'
