Iran threatens to mine the Strait of Hormuz, petroleum markets react, world economies take notice, and more U.S. and allied naval forces are sent to the region, upping the ante for Tehran and the U.S. Navy.
Iran’s top naval commander, Adm. Habibollah Sayyari, late last year warned that closin the strait would be “easier than drinking a glass of water.” The Obama administration publicly dismissed the threat as “aber rattling,” but also privately informed Tehran that attempting to close the strait would trigger a U.S. military response.
“The laying of mines in international waters is an act of war,” Vice Adm. Mark Fox, commander of the U.S. Navy’s Fifth Fleet, said in a Feb. 12 interview.
“We would, under the direction of the national leadership, prevent that from happening. We always have the right and obligation of self-defense and this falls in self-defense. If we did nothing and allowed some mining,” he noted, “it would be a long and difficult process to clear them.”
Whether an “act of war” or not (the international rules — admittedly more honored in their breach than observation— do allow for peacetime mining of high-seas areas under certain strict conditions. Iranian officials have threatened to close the Strait of Hormuz in response to U.S. and international sanctions over its nuclear program.
