Defense Tech reports that Iran plans to establish a "powerful force" off the U.S. eastern seaboard.
While this propaganda is probably for internal consumption, if followed through it could pose a threat to states on the Gulf of Mexico. The main problem with this is the range factor, as the eastern seaboard is over 6,000 kilometers from Iran's major naval base at Bandar Abbas. However, Iran does have some friends in the region, Venezuelan dictator Hugo Chavez is a friend of Iran's and would probably offer Iran the ability to refuel at a Venezuelan port. And of course there is always Cuba, which is stilled ruled by the old fool named Fidel Castro, who would also probably offer Iran the ability to refuel at a Cuban port.
While it is highly unlikely that Iran will mount a naval expedition to the U.S. eastern seaboard, if they do it could pose a threat to the many Oil Rigs in the Gulf of Mexico. Along with the massive fishing fleet that works the Gulf. As this continues to develop it will be interesting to see if Iran actually attempts this. If so, how do you say "live fire exercise" in Farsi?
