Iran Gulf Buildup Not Aimed At Challenging U.S., Cosgriff Says

Iran’s build-up of its naval forces in the Persian Gulf remains consistent and doesn’t suggest any short-term intent to confront the U.S. Navy or disrupt oil traffic, the head of U.S. naval forces in the Gulf said today.

Don’t `Hyperventilate’ …  Cosgriff urged the public, including oil-industry analysts, not to “hyperventilate” over such encounters.

“Put it into context — you should be able to see the difference between something really extraordinary and something where it looks like they got a little close and nothing really happened,” he said. “Don’t get hyperventilated over these things.”

Great example of applying the variation principle.  “Something really extraordinary” is a conceptual reference to a “Signal” or special cause of variation as opposed to normal (nothing unusual) common cause of variation.
