I wrote previously that we had sent two aircraft carriers and their battle groups to join two battlegroups already in the Persian Gulf, and about the significance of this move. At the time I theorized that the move was related to a move against Iran, but then later thought that perhaps we have advance knowledge of the strike on Georgia. Turns out, not only was I right on both counts, but what I then termed as \”not a trivial chess piece in a global chessboard\” is just the tip of the iceberg.
There is a massive naval fleet heading for the gulf, most of which just completed Operation Brimstone, a joint US/UK/French/Brazil naval wargame. From descriptions of Operation Brimstone, it appears it concentrated on international cooperation to conduct military operations in littoral waters. All handy skills to have if one is planning a international naval blockade of another country.
Previously, I was aware of only the USS Theodore Roosevelt, the USS Ronald Reagan and their battle groups heading for the Gulf. Now it appears they are joined by the USS Iwo Jima, an amphibious assault ship (similar to the Peleliu), the UK Royal Navy HMS Ark Royal aircraft carrier, and her battle group, along with assorted French naval assets including the nuclear attack submarine Amethyste and French Naval Rafale fighter jets on-board the USS Theodore Roosevelt. By virtually any measure, that is a massive amount of firepower, especially combined with the forces already in the Gulf. Forces which include the USS Abraham Lincoln and her battlegroup, the USS Peleliu and her battle group, at least one US nuclear attack sub and miscellaneous other forces. This is the largest buildup of US allied naval forces in the Gulf since the invasion of Iraq.
There are several possible reasons for this buildup of forces:
1) The US and several allies have decided to enforce at least a partial naval blockade of Iran
2) The US and several allies are preparing for an Israeli and/or US strike on Iranian nuclear facilities
3) The US and several allies are preparing for an invasion of Iran.
Option #3 is the least likely, as this buildup is happening absent any major redeployment of air and ground forces. Both of these would be necessary for an invasion. Also with it\’s easily deployed ground forces already committed in Iraq and Afghanistan, and with the potential of action in Georgia. The timing of this, make option #3 severely unlikely.
Option #2 while possible, has become increasingly unlikely. Israel certainly has the capability. And if they feel the US isn\’t gonna do it, then they may feel the need to step up. And they may very well be at that stage. However, the US just rejected a request from Israel for military equipment necessary to make a strike on Iran. So clearly the Israelis lack some equipment necessary to make a strike. Even if they could manufacture it themselves, they are clearly not at a stage were a strike on Iran is imminent hence no need for a force buildup.
Which leaves us option #3, which I think it increasingly likely, especially considering that a majority of the forces involved just participated in a training exercise practicing precisely this. Plus a naval blockade would be a likely next step in the escalation of force to get Iran to comply with UN demands. While Iran is rich in oil, it has limited domestic refining capability. Which means while it exports lots of oil, it also has to import benzene in massive quantities. So a naval blockade would cripple their economy and that tends to draw attention.
Now certainly a much smaller force would certainly be capable of a naval blockade. The fact that such a large force is being arrayed also says quite a bit about the operational planning that went into this, and tends to imply two different possibilities.
First that it was considered possible that such a blockade would be resisted either by Iran or others (i.e. Russia). In the latter case, this formidable force would likely be intended to make intervention seem futile, or at least impractical. While Russia does have forces in the area, most notably the carrier Admiral Kuznetsov, in the Mediterranean, it\’s aircraft would have to pass over Iraq, and the US forces deployed there, in order to reach this flotilla.
Almost certainly the Iranians would attempt to resist as well, through quite a few different methods. Air attacks from land based aircraft would seemingly be met by aircraft from the four different carriers. Helicopters from the amphibious assault ships would likely be tasked to anti-sub detail. And the numerous warships in the battlegroups would fend of the Iranian Revolutionary Guard high-speed boats, functioning as suicide boats, similar to the attack on the USS Cole.
Almost certainly there would be an attempt by Iran to close the oil route chokepoint (only 21 miles wide) of the Strait of Hormuz, since one side is controlled by Iran, and the other by US allies United Arab Emirates and Oman. With the forces currently being positioned in the Gulf, it seems very likely that the US would be able to keep this route open, and prevent any attempts by Iran to break through the blockade.
Of course, a naval blockade is generally considered an act of war. So it\’s unlikely that everything will be just this simple. The board is set, the chess pieces are moving. This game is about to get interesting.
