(Roosevelt said something about walking softly and carrying a big stick. Indeed. Old, but gotta love F-14s)
The pointless posturing of our title is by the Iranian regime. So it seems the Iranians backed down, and then having backed down, told the US Navy that it couldn't operate it's aircraft carriers in the Persian Gulf (or, if you want to annoy the Iranians, the Arabian Gulf - isn't language funny.)
The US Navy gave Iran a stern ignoring. Quelle surprise.
And it will carry on until the Iranians need another external mini-crisis for internal political pressures. At least President Obama doesn't have to (although the GOP do, it seems).
Good going USN.
