Iranian Parliament Speaker Mohammad Bagher Ghalibaf has asserted that military threats and the potential for regional escalation forced the United States to lift a blockade immediately, bypassing a previously negotiated 30-day period. Ghalibaf claimed that following an attack on the southern suburbs of Beirut, he halted negotiations and warned of strikes against Israel, a stance he says compelled the U.S. to act.

As tensions persist, Ghalibaf has rejected further pressure from Washington for new concessions. He criticized U.S. Treasury Secretary Scott Bessent and Defense Secretary Pete Hegseth, stating that Iran will not exceed its original agreements. Ghalibaf indicated that Iran may continue to close the Strait of Hormuz until the United States fulfills specific obligations, including the release of frozen assets, the removal of oil sanctions, and the cessation of hostilities on all fronts.
