Trump Opens Strait of Hormuz Naval Blockade, Links Talks’ Collapse to Iran Nuclear Refusal
President Trump ordered a naval blockade of the Strait of Hormuz after 21-hour Islamabad talks collapsed, saying Iran refused to give an “affirmative” pledge not to pursue a nuclear weapon despite agreement on most points; two U.S. destroyers transited the strait to begin clearing IRGC-laid mines as initial implementation. Trump claimed his April 7 threats had forced Tehran into talks and predicted further pressure would yield concessions, while Pakistan and Oman urged extending the ceasefire and negotiations and analyst Rob Malley warned both sides’ belief they hold the upper hand makes meaningful compromise unlikely.
