Iran has intensified its rhetoric and military posturing against the United States, with reports suggesting unconventional tactics like deploying mine-equipped dolphins to counter the US maritime blockade. The Wall Street Journal cited Iranian officials on April 30, 2026, revealing this strategy amid a prolonged blockade disrupting shipping in the Persian Gulf and Strait of Hormuz since February 2026. Iranian military advisor Mohsen Rezaei escalated threats on May 3, warning the US that Tehran would "send ships and troops to the cemetery." Meanwhile, Foreign Ministry spokesperson Bagheri called for Gulf countries to strengthen regional cooperation, emphasizing reduced external influence.Asahi Shimbun+2
Iran is reportedly considering using trained dolphins armed with mines to target US forces, reviving Cold War-era military animal programs. The IRGC has simultaneously intensified control over the Strait of Hormuz, submitting a formal complaint to the International Maritime Organization about US actions endangering maritime safety. Recent explosions in Tehran and uranium enrichment tensions further complicate the crisis.Asahi Shimbun+2
President Masoud Pezeshkian reiterated that Persian Gulf security requires regional cooperation, dismissing unilateral US measures. The blockade has driven oil prices to $126 per barrel, with Iran accusing the US and Israel of threatening global economic stability. Bagheri's May 4 statement emphasized creating a regional mechanism to safeguard mutual interests while reducing external power influence.Huanqiu+2
The US maintains the blockade targets Iranian oil shipments, but Iran predicts its failure, citing political motivations. Analysts like Oliver McTernan note Iran "will not capitulate," calling US actions a miscalculation. With Iran promising military responses and the blockade now in its third month, the stalemate risks broader economic and security repercussions.France 24+2
The dolphin mine tactic traces back to Cold War programs where the US and USSR studied marine mammals for military use. While the US Navy denies offensive deployment, Iran's potential adoption marks a significant escalation in asymmetric warfare. The blockade has pushed Tehran toward increasingly unconventional countermeasures.Asahi Shimbun+1
