Iran clearly stands to gain from this dynamic in the short term as it seeks to reshape the balance of power in the world's most active energy arteries
But Iranian power is neither deep nor absolute. Instead, Tehran finds itself racing against a timetable that hinges not only on the U.S. ability to shift its attention from its ongoing wars in the Middle East but also on Turkey’s ability to grow into its historic regional role.The Iranian Position
Iranian Defense Minister Ahmad Vahidi said something last week that caught our attention. Speaking at Iran’s first Strategic Naval Conference in Tehran on July 13, Vahidi said the United States is “making endeavors to drive a wedge between regional countries with the aim of preventing the establishment of an indigenized security arrangement in the region, but those attempts are rooted in misanalyses and will not succeed.” The effect Vahidi spoke of refers to the 
Iranian redefinition of Persian Gulf power dynamics, one that in Iran’s ideal world ultimately would transform the local political, business, military and religious affairs of the Gulf states to favor the Shia and their patrons in Iran.
From Iran’s point of view, this is a natural evolution, and one worth waiting centuries for. It would see power concentrated among the Shia in Mesopotamia, eastern Arabia and the Levant at the expense of the Sunnis who have dominated this land since the 16th century, when the Safavid Empire lost Iraq to the Ottomans. Ironically, Iran owes its thanks for this historic opportunity to its two main adversaries — the Wahhabi Sunnis of al Qaeda who carried out the 9/11 attacks and the “Great Satan” that brought down Saddam Hussein. Should Iran succeed in filling a major power void in Iraq, a country that touches six Middle Eastern powers and demographically favors the Shia, Iran would theoretically have its western flank secured as well as an oil-rich outlet with which to further project its influence.
So far, Iran’s plan is on track. Unless the United States permanently can station substantial military forces in the region, Iran replaces the United States as the most powerful military force in the Persian Gulf region. In particular, Iran has the military ability to threaten the Strait of Hormuz and has a clandestine network of operatives spread across the region. Through its deep penetration of the Iraqi government, Iran is also in the best position to influence Iraqi decision-making. Washington’s obvious struggle in trying to negotiate an extension of the U.S. deployment in Iraq is perhaps one of the clearest illustrations of Iranian resolve to secure its western flank. The Iranian nuclear issue, as we have long argued, is largely a sideshow; a nuclear deterrent, if actually achieved, would certainly enhance Iranian security, but themost immediate imperative for Iran is to consolidate its position in Iraq. And as this weekend’s Iranian incursion into northern Iraq — ostensibly to fight Kurdish militants — shows, Iran is willing to make measured, periodic shows of force to convey that message.
While Iran already is well on its way to accomplishing its goals in Iraq, it needs two other key pieces to complete Tehran’s picture of a regional “indigenized security arrangement” that Vahidi spoke of. The first is an understanding with its main military challenger in the region, the United States. Such an understanding would entail everything from ensuring Iraqi Sunni military impotence to expanding Iranian energy rights beyond its borders to placing limits on U.S. military activity in the region, all in return for the guaranteed flow of oil through the Strait of Hormuz and an Iranian pledge to stay clear of Saudi oil fields.
The second piece is an understanding with its main regional adversary, Saudi Arabia. Iran’s reshaping of Persian Gulf politics entails convincing its Sunni neighbors that resisting Iran is not worth the cost, especially when the United States does not seem to have the time or the resources to come to their aid at present. No matter how much money the Saudis throw at Western defense contractors, any military threat by the Saudi-led Gulf Cooperation Council states against Iran will be hollow without an active U.S. military commitment. Iran’s goal, therefore, is to coerce the major Sunni powers into recognizing an expanded Iranian sphere of influence at a time when U.S. security guarantees in the region are starting to erode.
Of course, there is always a gap between intent and capability, especially in the Iranian case. Both negotiating tracks are charged with distrust, and meaningful progress is by no means guaranteed. That said, a number of signals have surfaced in recent weeks leading us to examine the potential for a Saudi-Iranian accommodation, however brief that may be.
The Saudi Position
Not surprisingly, Saudi Arabia is greatly unnerved by the political evolution in Iraq. The Saudis increasingly will rely on regional powers such as Turkey in trying to maintain a Sunni bulwark against Iran in Iraq, but Riyadh has largely resigned itself to the idea that Iraq, for now, is in Tehran’s hands. This is an uncomfortable reality for the Saudi royals to cope with, but what is amplifying Saudi Arabia’s concerns in the region right now — and apparently nudging Riyadh toward the negotiating table with Tehran — is the current situation in Bahrain.
When Shiite-led protests erupted in Bahrain in the spring, we did not view the demonstrations simply as a natural outgrowth of the so-called Arab Spring. There were certainly overlapping factors, but there was little hiding the fact that Iran had seized an opportunity to pose a nightmare scenario for the Saudi royals: an Iranian-backed Shiite uprising spreading from the isles of Bahrain to the Shiite-concentrated, oil-rich Eastern Province of the Saudi kingdom.
This explains Saudi Arabia’s hasty response to the Bahraini unrest, during which it led a rare military intervention of GCC forces in Bahrain at the invitation of Manama to stymie a broader Iranian destabilization campaign. The demonstrations in Bahrain are far calmer now than they were in mid-March at the peak of the crisis, but the concerns of the GCC states have not subsided, and for good reason. Halfhearted attempts at national dialogues aside, Shiite dissent in this part of the region is likely to endure, and this is a reality that Iran can exploit in the long term through its developing covert capabilities.
When we saw in late June that Saudi Arabia was willingly drawing down its military presence in Bahrain at the same time the Iranians were putting out feelers in the local press on an almost daily basis regarding negotiations with Riyadh, we discovered through our sources that the pieces were beginning to fall into place for Saudi-Iranian negotiations. To understand why, we have to examine the Saudi perception of the current U.S. position in the region.
The Saudis cannot fully trust U.S. intentions at this point. The U.S. position in Iraq is tenuous at best, and Riyadh cannot rule out the possibility of Washington entering its own accommodation with Iran and thus leaving Saudi Arabia in the lurch. The United States has three basic interests: to maintain the flow of oil through the Strait of Hormuz, to reduce drastically the number of forces it has devoted to fighting wars with Sunni Islamist militants (who are also by definition at war with Iran), and to try to reconstruct a balance of power in the region that ultimately prevents any one state — whether Arab or Persian — from controlling all the oil in the Persian Gulf. The U.S. position in this regard is flexible, and while developing an understanding with Iran is a trying process, nothing fundamentally binds the United States to Saudi Arabia. If the United States comes to the conclusion that it does not have any good options in the near term for dealing with Iran, a U.S.-Iranian accommodation — however jarring on the surface — is not out of the question.
More immediately, the main point of negotiation between the United States and Iran is the status of U.S. forces in Iraq. Iran would prefer to see U.S. troops completely removed from its western flank, but it has already seen dramatic reductions. The question for both sides moving forward concerns not only the size but also the disposition and orientation of those remaining forces and the question of how rapidly they can be reoriented from a more vulnerable residual advisory and assistance role to a blocking force against Iran. It also must take into account how inherently vulnerable a U.S. military presence in Iraq (not to mention the remaining diplomatic presence) is to Iranian conventional and unconventional means.
The United States may be willing to recognize Iranian demands when it comes to Iran’s designs for the Iraqi government or oil concessions in the Shiite south, but it also wants to ensure that Iran does not try to overstep its bounds and threaten Saudi Arabia’s oil wealth. To reinforce a potential accommodation with Iran, the United States needs to maintain a blocking force against Iran, and this is where the U.S.-Iranian negotiation appears to be deadlocked.
The threat of a double-cross is a real one for all sides to this conflict. Iran cannot trust that the United States, once freed up, will not engage in military action against Iran down the line. The Americans cannot trust that the Iranians will not make a bid for Saudi Arabia’s oil wealth (though the military logistics required for such a move are likely beyond Iran’s capabilities at this point). Finally, the Saudis can’t trust that the United States will defend it in a time of need, especially if the United States is preoccupied with other matters and/or has developed a relationship with Iran that it feels the need to maintain.
When all this is taken together — the threat illustrated by Shiite unrest in Bahrain, the tenuous U.S. position in Iraq and the potential for Washington to strike its own deal with Tehran — Riyadh may be seeing little choice but to search out a truce with Iran, at least until it can get a clearer sense of U.S. intentions. This does not mean that the Saudis would place more trust in a relationship with their historical rivals, the Persians, than they would in a relationship with the United States. Saudi-Iranian animosity is embedded in a deep history of political, religious and economic competition between the two main powerhouses of the Persian Gulf, and it is not going to vanish with the scratch of a pen and a handshake. Instead, this would be a truce driven by short-term, tactical constraints. Such a truce would primarily aim to arrest Iranian covert activity linked to Shiite dissidents in the GCC states, giving the Sunni monarchist regimes a temporary sense of relief while they continue their efforts in trying to build up an Arab resistance to Iran.
But Iran would view such a preliminary understanding as the path toward a broader accommodation, one that would bestow recognition on Iran as the pre-eminent power of the Persian Gulf. Iran can thus be expected to make a variety of demands, all revolving around the idea of Sunni recognition of an expanded Iranian sphere of influence — a very difficult idea for Saudi Arabia to swallow.
This is where things get especially complicated. The United States theoretically might strike an accommodation with Iran, but it would do so only with the knowledge that it could rely on the traditional Sunni heavyweights in the region eventually to rebuild a relative balance of power. If the major Sunni powers reach their own accommodation with Iran, independent of the United States, the U.S. position in the region becomes all the more questionable. What would be the limits of a Saudi-Iranian negotiation? Could the United States ensure, for example, that Saudi Arabia would not bargain away U.S. military installations in a negotiation with Iran?
The Iranian defense minister broached this very idea during his speech last week when he said, “the United States has failed to establish a sustainable security system in the Persian Gulf region, and it is not possible that many vessels will maintain a permanent presence in the region.” Vahidi was seeking to convey to fellow Iranians and trying to convince the Sunni Arab powers that a U.S. security guarantee in the region does not hold as much weight as it used to, and that with Iran now filling the void, the United States may well face a much more difficult time trying to maintain its existing military installations.
The question that naturally arises from Vahidi’s statement is the future status of the U.S. Navy’s 5th Fleet in Bahrain, and whether Iran can instill just the right amount of fear in the minds of its Arab neighbors to shake the foundations of the U.S. military presence in the region. For now, Iran does not appear to have the military clout to threaten the GCC states to the point of forcing them to negotiate away their U.S. security guarantees in exchange for Iranian restraint. This is a threat, however, that Iran will continue to let slip and even one that Saudi Arabia quietly could use to capture Washington’s attention in the hopes of reinforcing U.S. support for the Sunni Arabs against Iran.
The Long-Term Scenario
The current dynamic places Iran in a prime position. Its political investment is paying off in Iraq, and it is positioning itself for negotiation with both the Saudis and the Americans that it hopes will fill out the contours of Iran’s regional sphere of influence. But Iranian power is not that durable in the long term.
Iran is well endowed with energy resources, but it is populous and mountainous. The cost of internal development means that while Iran can get by economically, it cannot prosper like many of its Arab competitors. Add to that a troubling demographic profile in which ethnic Persians constitute only a little more than half of the country’s population and developing challenges to the clerical establishment, and Iran clearly has a great deal going on internally distracting it from opportunities abroad.
The long-term regional picture also is not in Iran’s favor. Unlike Iran, Turkey is an ascendant country with the deep military, economic and political power to influence events in the Middle East — all under a Sunni banner that fits more naturally with the region’s religious landscape. Turkey also is the historical, indigenous check on Persian power. Though it will take time for Turkey to return to this role, strong hints of this dynamic already are coming to light.
In Iraq, Turkish influence can be felt across the political, business, security and cultural spheres as Ankara is working quietly and fastidiously to maintain a Sunni bulwark in the country and steep Turkish influence in the Arab world. And in Syria, though the Alawite regime led by the al Assads is not at a breakpoint, there is no doubt a confrontation building between Iran and Turkey over the future of the Syrian state. Turkey has an interest in building up a viable Sunni political force in Syria that can eventually displace the Alawites, while Iran has every interest in preserving the current regime so as to maintain a strategic foothold in the Levant.
For now, the Turks are not looking for a confrontation with Iran, nor are they necessarily ready for one. Regional forces are accelerating Turkey’s rise, but it will take experience and additional pressures for Turkey to translate rhetoric into action when it comes to meaningful power projection. This is yet another factor that is likely driving the Saudis to enter their own dialogue with Iran at this time.
The Iranians are thus in a race against time. It may be a matter of a few short years before the United States frees up its attention span and is able to re-examine the power dynamics in the Persian Gulf with fresh vigor. Within that time, we would also expect Turkey to come into its own and assume its role as the region’s natural counterbalance to Iran. By then, the Iranians hope to have the structures and agreements in place to hold their ground against the prevailing regional forces, but that level of long-term security depends on Tehran’s ability to cut its way through two very thorny sets of negotiations with the Saudis and the Americans while it still has the upper hand.
