Iran Bluster Is about Red Lines, Not War

In the past week, American-Iranian tensions flared to heights not seen since the Reagan years, when U.S. and Iranian ships and planes faced off in the Persian Gulf. Not only have Iranian irregular forces apparently sabotaged four ships off the major Emirati port of Fujairah with either magnet bombs or underwater drones, but a subsequent drone attack on a Saudi pipeline amplified tensions to a new level.Even on the best of days in hyper-partisan Washington, there are enough polemics to go around.
