Diplomatic efforts to resolve the conflict between the United States and Iran have entered a critical phase as Tehran begins reviewing Washington’s latest position on ending the war. President Donald Trump has indicated a willingness to wait a few days for a response but has cautioned that the U.S. is prepared to resume military actions if an agreement is not reached. This diplomatic track is being supported by regional intermediaries, including Turkish President Tayyip Erdogan, who recently held a call with President Trump to endorse a ceasefire extension, and Pakistani officials who are facilitating back-channel communications. Despite these talks, military and economic pressure continues to mount. U.S. Central Command confirmed that the U.S. military boarded the Iranian-flagged tanker M/T Celestial Sea in the Gulf of Oman on Wednesday for allegedly violating a blockade. Concurrently, the Islamic Revolutionary Guard Corps (IRGC) has issued a stern warning, suggesting that any further attacks on Iranian soil will result in a war that expands "beyond the Middle East," signaling a shift toward threats of global retaliation. On the ground in Iran, the situation for civilians is becoming increasingly difficult. The country is currently experiencing its longest and most intense internet blackout in history, which is combined with a worsening economic crisis. Reports indicate that the Iranian government is attempting to manage internal dissent and control the flow of information while its military sources claim to possess modern, untested weaponry ready for use if the ceasefire fails.
