Nobody seems to be mentioning that speedboat tactics are remarkably similar to the tactics employed by General Paul Van Riper when he whipped the Pentagon using lo-tech tactics during the Operation Millennium Challenge war game for the Gulf. Shystee wrote:

Van Riper was the commander of a fictional middle eastern state (Iraq, or possibly Iran) attempting to repel a US attack.

The games were designed to test experimental new tactics and doctrines advocated by the defence secretary, Donald Rumsfeld, and were referred to in Pentagon-speak as “military transformation”.
…
[Van Riper] sent orders with motorcycle couriers to evade sophisticated electronic eavesdropping equipment. When the US fleet sailed into the Gulf, he instructed his small boats and planes to move around in apparently aimless circles before launching a surprise attack which sank a substantial part of the US navy. The war game had to be stopped and the American ships “refloated” so that the US forces stood a chance.

More from the Guardian. The beauty part is that Rummy's Pentagon didn't like the outcome, so they rewrote the war game rules so Van Riper would lose and then ran the game again. Mission Accomplished!

I don't know whether the recent tapes of Iranian speedboats are real or fake or a combination of both.

Whatever, the tapes (and the event, if real) are clearly designed to send a message, and the results of Millenium Challenge have to be part of it.

But what's the message, and who's sending it?

The Mighty Quinn?
