I confess that I've always thought the likelihood of foreign troops conducting military operations in the United States was extremely unlikely. And here a U.S. Marine says that, if people "mess" with one of them, they mess with all of them, presumably referring to SOF from multiple countries. It takes me back to the National Guardsman interviewed during Katrina who said he may have to shoot Americans.

This sort of thing, if people were to learn of it beforehand--they are usually announced, as evidenced by the spectators in the parking garage in the photo--would make a great first dance.
