You are seriously funny. The Iranians have just proven that they can take an oil tanker if they want to do so. So please, tell me, how exactly does risking the lives of our military men to take it back prevent them from doing it again? And again. And again.
Somali pirates used to take huge tankers and those guys had nothing but small arms.
Policy from tanker owners usually prohibit fighting back. Thats changing and thats why huge ships near Somalia are not being taken - ex SAS and SEALS kill the pirates.
Tomahawks and other weapon systems are unmanned so no risk to US lives.
Not all fights require US lives put at risk.
