Legal experts say a U.S. submarine’s deadly attack on an Iranian warship does not appear to have violated international or American military law. It's not clear to the experts, though, whether the sub took sufficient measures to rescue nearly three dozen survivors. Legal questions are swirling about the underpinnings for the entire U.S.-Israeli military operation against Iran and the aftermath of the torpedo attack on the IRIS Dena in the Indian Ocean. Eighty-seven people died and 32 Iranian sailors were rescued after the sub torpedoed the Dena in international waters near Sri Lanka.
