[Ed. – Call it “naval distancing.” I know this will sound good to a lot of people. The Navy has always avoided stating a distance for this purpose, because setting it in stone is just a bad idea. It invites hovering at the declared perimeter and can lead to complacency. It can also be misleading in terms of our reactions; it may be preferable for self-defense to react to a potential threat when it’s further away. If that’s necessary, the stated “100 meters” isn’t something the American taxpayers’ Navy is going to hold ourselves to. We’re bringing every sailor and Marine and your $1 billion warship back in one piece, and hang the paper antes on distancing. But we’ll see how it goes.]
In an alert that appeared aimed squarely at Iran, the U.S. Navy issued a warning on Tuesday to mariners in the Gulf to stay 100 meters (yards) away from U.S. warships or risk being “interpreted as a threat and subject to lawful defensive measures.”
The notice to mariners, which was first reported by Reuters, follows U.S. President Donald Trump’s threat last month to fire on any Iranian ships that harass Navy vessels.
“Armed vessels approaching within 100 meters of a U.S. naval vessel may be interpreted as a threat,” according to the text of the notice …
A U.S. official, speaking on condition of anonymity, said the new notice to mariners was not a change in the U.S. military’s rules of engagement.
