U.S. Blockade Halts Iran Port Traffic as Maritime Tensions Rise

The U.S. naval blockade of Iranian ports has effectively halted shipping traffic in its first 24 hours, with U.S. Central Command reporting that six merchant vessels turned back and over a dozen warships are enforcing the restrictions. Tehran has characterized the blockade as 'piracy' and warned that no port in the Persian Gulf or Arabian Sea remains safe, signaling a potential expansion of maritime hostilities beyond the Strait of Hormuz. In Iraq, the conflict is increasingly involving Iranian-backed militias, which have launched attacks on U.S. targets. The Trump administration has responded with retaliatory strikes on Iraqi soil, heightening fears of a regional spillover. French President Emmanuel Macron intervened on Wednesday, calling for immediate negotiations between Washington and Tehran to prevent the seven-week conflict from devolving into a broader war. Despite the military escalation, backchannel diplomatic discussions have reportedly narrowed some gaps regarding Iran's nuclear program. Significant hurdles remain, as the U.S. demands a 20-year suspension of nuclear activities and the removal of enriched materials, while Iran has proposed a timeline of three to five years. Vice President JD Vance noted that deep mistrust continues to hinder progress toward a comprehensive sanctions relief agreement.
