Why Killing the Iran Deal Could Start the next War in the Middle East

The JCPOA is not to blame for Iran’s success in the regional power game, and reversing it will not deprive Iran of its gains.

There are troubling signs that the Trump administration is itching for a fight with Iran. While the White House recently certified that Tehran was complying with the nuclear deal, fresh sanctions and thinly veiled references to regime change should raise serious concern that the administration will be searching for any excuse to avoid recertifying Iran’s compliance come the next review in October. In fact, President Donald Trump tasked a team in the White House with coming up with reasons to withhold certification at the next opportunity. And in a July 25 interview with the Wall Street Journal Trump prejudged the October outcome, saying he fully expected Iran to be declared noncompliant.

Breaking the nuclear deal, presumably to keep a campaign promise, could put Washington on a slippery slope towards a military confrontation with Iran. Sabotage of the accord that Iran negotiated, not only with the United States, but also with Russia, China, the United Kingdom, France and Germany, would be received in Tehran as a message that Washington is preparing for military action, and that it must therefore prepare for the worst. This path towards confrontation would wreak havoc on an already unstable Middle East, undermine U.S. national security interests, and potentially put American lives at risk.

There are legitimate reasons for Washington to be alarmed about Iran’s behavior. Tehran has projected its influence deep into the Arab heartland using its al-Quds expeditionary force and through its patronage of militias like Hezbollah, the Iraqi popular mobilization units, the Houthis in Yemen and over 100,000 militiamen in Syria. Its game of tug-of-war with the United States in Iraq is intended to pull Baghdad more fully into Tehran’s political orbit and away from Washington. And provocatively it flexes it's muscle by conducting missile tests and arresting U.S. visitors to Iran.

But distinguishing fact from fiction on Iran is necessary, particularly amidst the bluster from the White House and Congress. It is true that Tehran’s influence in the region has been growing steadily, particularly since Russia entered Syria in 2015 to buttress President Bashar al-Assad, a goal shared by Iran. But it is false that the nuclear deal is somehow to blame for Iran’s success in the regional power game, and that reversing it will deprive Iran of that capability. What has given Iran the capacity to meddle isn’t the nuclear deal, but rather the large political vacuum that now exists smack in the center of the Arab world. The wars in Syria and Iraq in particular, as well as the conflict in Yemen, have hollowed out the center of the Arab world, creating a gaping security hole that has lured in Iran, but also Saudi Arabia and Turkey, into a kind of conflict trap from which it is easier to enter than exit.

Iran has inflamed these conflicts and efforts by Washington to counterbalance Tehran’s regional power make sense. But it is important to understand that the real threat to American national security interests isn’t Iran per se, but rather the vacuum created by the civil wars that allows Tehran and other regional powers to step in. It is the collapse of the regional order, with all the security risks this entails, that is the real threat to U.S. interests. The Syrian civil war, for example, spawned a new Al Qaeda affiliate, Hay’at Tahrir al-Sham, which could eventually take root elsewhere in the region. The conflicts in Syria, Iraq, Yemen and Libya make Trump’s campaign promise of permanently eradicating ISIS unrealizable. The longer the wars continue, the greater is the risk that already weakened countries like Jordan and Lebanon will succumb to civil war, and the greater the threat of instability becomes for Saudi Arabia. Plus, ongoing wars give Russia the opportunity to cement its position as the indispensable actor in the Middle East, a sub-optimal scenario for both the region and the United States.

It is these corrosive effects of the civil wars that represent the real threat to U.S. interests. It should be this overarching challenge, and not a singular focus on Iran, that energizes Washington’s role in the region.

Backing out of the nuclear deal risks further inflaming these civil wars that represent the real threat to U.S. interests in the Middle East. Here are how events could unfold and the regional situation deteriorate should Washington breach the nuclear deal. Tehran will interpret any moves to undermine the nuclear accord as a shot across the bow on the road towards regime change, and it will use all means at its disposal, including its assets in Syria, Iraq, Lebanon and Yemen, to beef up its deterrence and retaliatory capabilities. Under threat, Iran could stir up Shia restiveness in Bahrain and Saudi Arabia, increase support for the Houthis in Yemen, put Hezbollah on alert on Lebanon’s border with Israel, and sow more mischief in Syria and Iraq. Since these actions would take place not in Iran, but in the most volatile areas of the Middle East, they would likely lead to further escalation of the civil wars and greater instability in the region. They could also be sufficiently provocative to push the Trump administration towards military action and into the conflict trap.
