Iran's Kamikaze Hormuz Threat
BY AFSHON OSTOVAR | JANUARY 9, 2012
When Iran's vice president, Mohammad Reza Rahimi, declared on Dec. 27 that "not a drop of oil will pass through the Strait of Hormuz" if Western countries followed through with threats of escalated sanctions over its nuclear program, the world sat up and took notice. Since then, tensions have run high in the Persian Gulf, with Iran holding naval exercises and U.S. Secretary of Defense Leon Panetta warning Iran that closing the strait would be a "red line" for the United States.
Newspaper headlines are warning of a possible conflict breaking out over one of the most important shipping lanes on the planet, through which almost 20 percent of the world's oil passes each day. Analysts and commentators can't seem to decide how seriously to rate this risk: They have generally argued that Iran's military (and especially naval) capabilities are either insignificant or extreme threats to U.S. and allied forces in the region. So which is it? Is the Iranian navy as dangerous as it claims to be? Can Iran really shut the Strait of Hormuz?
The truth is that Iran does possess a number of tools to harass, challenge, and even harm opposing naval forces, but its overall arsenal is limited, ramshackle, and untested in combat. Iran's military commanders know that their naval capabilities are ill-suited for direct engagement with U.S. forces. Iranian traditional naval vessels and aircraft are no match for their American counterparts, and Iran possess too few of both to endure any extended engagement. Unable to challenge U.S forces with equal strength and firepower, Iran's military planners have designed "asymmetric" tactics that utilize the greater speed and agility of their maritime assets.
Iran's small boats and midget submarines would be central to any Iranian naval engagement, and are likely the ones that would be the most difficult to initially counter. Iran has also produced thousands of naval mines, which could be littered throughout strategic sea lanes in the Persian Gulf or employed as defensive measures around key Iranian maritime infrastructure. The United States has the capability to effectively deal with naval mines, but their use by Iran would certainly complicate maritime traffic for a period of time.
This asymmetric approach to warfare, which is borne out of Iran's longstanding technological disadvantages vis-à-vis the United States and its allies, is the military basis for its particular threat to close the Strait of Hormuz. Iran cannot compete with U.S. forces directly, but the collective marshaling of its maritime assets (mines, small boats, midget subs, etc.) could severely test the United States' ability to maintain security in the Persian Gulf.

Closing the Hormuz strait -- or more likely, creating a hostile environment in the Gulf that leads to a drastic decline in maritime shipping through it -- is probably the most extreme and certainly the most politically and economically damaging act that Iran's maritime forces could achieve. While the impact this would have on Iran, the United States, and Arab states in the region, is debatable, Iran understands that few if any would like to find out. This is Iran's answer to the United States' "all options on the table," and for all of its saber-rattling and exaggerated bluster, is something its forces could accomplish.
Yet, as Chairman of the Joint Chiefs of Staff General Martin Dempsey recently stated, Iran's ability to keep the strait closed or constricted would likely be short lived. Because of the military operations that would be involved, and the damage it would do to the economies of the region, closing the strait would likely be considered an act of war against the United States and its Gulf allies. U.S. retaliation against Iran would thus be a near certainty, putting at risk much of Iran's maritime and littoral military assets. The United States could end up destroying much of Iran's navy, air force, and land based artillery just to clear the way for re-opening the strait. The United States might also take the opportunity to target Iran's nuclear sites, if not move to topple the Iranian regime altogether. Regional opinion (especially that of the United States' Arab allies) will most likely support military operations in such a context, and the international community will be hard-pressed not to support military action against an Iran that is willing to jeopardize world petroleum and gas markets for its own political purposes.
None of this means Iran's bluster should be dismissed. Iran has the capability to challenge U.S. naval forces and the ability to close the Strait of Hormuz, albeit for a limited period. There is no question that U.S. commanders take the threat that Iranian forces pose seriously. However, while Iran might have an advantage in limited, asymmetrical attacks, that advantage quickly dissipates in an open and extended conflict. A war with the United States -- especially if it included an Iranian attempt to close the Hormuz strait -- would have devastating effects on Iran's economy, military, regional relations, and international standing. Thus, initiating a conflict with U.S. forces, particularly a maritime conflict, would be a last-ditch, kamikaze act by the Iranians. Iranian leaders understand this, which is why their strategy up until now has been focused on preventing outright conflict with the United States.
Some Iranian military commanders, however, express confidence in Iran's ability to control Persian Gulf waters in a conflict scenario. Admiral Ali Fadavi, the commander of the Revolutionary Guards' navy, recently pointed to Iran's naval engagements during the so-called "tanker war" of the 1980s as proof that its forces could be successful against the United States. Yet the historical record really holds the opposite to be true.

| The weapon of choice in the Tanker War: Mirage F.1EQ-5, designed and built specially for the IrAF, launching an AM.39 Exocet during the trials in the Gulf of Biscay, in 1982. The IrAF started using the Exocet already in October 1981, six months before the Falklands War – and with slightly more success than the Argentineans. But, with the time and for a number of reasons – including the improved construction of modern merchant ships, introduction of improved countermeasures by Iranians, a highly effective convoy system, and poor Iraqi targeting procedures – this expensive weapon remained relatively ineffective, and could never seriously threat the flow of Iranian oil exports. Out of over 400 strikes in which some 600 Exocets were expended, some 250 hits were scored, causing a loss of 115 ships (less than 1% of all the ships which were underway through the Iranian side of the northern Persian Gulf between October 1981 and June 1988).

Although Iranian forces were able to attack and damage civilian shipping vessels during that period, and obstruct maritime traffic with naval mines, they proved to be outmatched by the mostly defensive countermeasures of the United States. What is more, Iran was far more desperate during this period, and the tanker war was effectively the last gasp of Iranian military ambition during a nearly eight-year war with Iraq. The United States was also trying to limit its participation in the conflict, and did not deem Iran a big enough threat to enter into a full-scale war against it.
The situation is obviously very different today. Iran's domestic problems and the intense pressure of international sanctions appear to be rattling the nerves of Iran's decision-makers. The United States is leading the sanctions effort against Iran and has made clear that it will not allow it to develop a nuclear weapon. However, even now, when tensions are acute, an Iranian-initiated war looks like a distant possibility, as does a preemptive U.S. strike. Yet, as opportunities for compromise evaporate, and as relations continue to sour, the likelihood of war is steadily increasing.
