The US Navy seems to have undergone a bit of an attitude adjustment in the last four years.
The naval force under Obama in January of 2016 suffered through the humiliation of having several American sailors taken prisoner by the Iranians in the Persian Gulf. After permitting the Iranians to board their vessel without a shot fired, the U.S. personnel were forced on their knees, hands behind their heads. The pictures of such were spread around the world. It was a snapshot reminiscent of the Iranian hostage drama of 1979-81.

Our fleet now has a different Commander-in-Chief and it shows. The Iranians were reminded of that fact on Sunday, as the USS Normandy searched one of their innocent looking smuggling vessels, a dhow, and viola, made a nice catch of the day.
