IRGC Navy broadcasting on international maritime Channel 16, the channel every ship in the world monitors, to declare the Strait of Hormuz closed and personally insult the president of the United States. "We'll open it by the order of our leader Imam Khamenei, not by the tweets of some idiot." "All vessels that have a connection with our enemies will be targeted if they try to pass." This is not a press release. This is a live radio call to shipping traffic in one of the most critical chokepoints on earth.
