The Obama administration has secured enough support in the Senate to ensure that the Iran nuclear deal will survive a congressional vote, but John Kerry warned remaining waverers that rejection of the agreement would be a “self-destructive blow” to US credibility.



Kerry was speaking in Philadelphia less than an hour after Democrat Barbara Mikulski became the 34th senator to support the deal, ensuring a landmark victory for the Obama administration’s efforts to prevent it being derailed.

Mikulski’s support for the agreement means that Obama has enough votes in the Senate to uphold his veto if Congress rejects the July deal as expected. But the adminstration is still hoping to amass 41 votes, which would spare Obama from having to use his veto and spend political capital.

Kerry said: “It’s hard to conceive of a quicker or more self-destructive blow to our nation’s credibility and leadership” than a vote against the agreement, known as the Joint Comprehensive Plan of Action (JCPOA). The secretary of state sought to dispel what he described as myths about the July deal which he said had begun to circulate “even before the ink was dry”.

At the top of his list was the belief that the agreement was based on trust.

“There is a not a single sentence or paragraph in this whole agreement that depends on promises or trust. Not one,” Kerry said. Instead, he insisted, Iranian compliance would be monitored by an unprecedented and hi-tech surveillance regimen installed by the UN nuclear watchdog, the International Atomic Energy Agency (IAEA).

Mikulski said she was convinced that the agreement blocked all four possible pathways to a nuclear bomb and created “the most robust and extensive verification system ever provided” by the IAEA.

“The conditions for the lifting of sanctions are strict and verifiable, and with continued international support, sanctions could snap back,” Mikulski said. “The lifting of the sanctions comes more quickly than I would like, and snapback will require continued international support. But after considering the alternatives, I will support this agreement.”

The 34-senator milestone represents a resounding defeat for efforts by the Republicans and the Israeli government to derail the agreement, but it is by no means the end of the political struggle.

The threshold means that Obama’s supporters could stop his veto being overridden if he needed to use it against a congressional vote of disapproval on the JCPOA, agreed with Iran, the US and five other world powers in July. Democrats are now trying to reach 41 votes, enough to block the disapproval vote in the Senate by filibuster, and spare Obama from having to spend political capital on a veto.

The result is already a stinging blow for the deal’s principal opponents, the Republican leadership, the American Israel Political Affairs Committee lobby group – which spent tens of millions of dollars campaigning against the JCPOA – and the Israeli prime minister, Binyamin Netanyahu, who waded into US politics to an extraordinary degree in an attempt to block it.

Diplomats say Wednesday’s milestone removes the more significant near-term threat to the survival of the agreement, which has already been endorsed by a UN Security Council vote. It is likely to accelerate preparatory steps on all sides to implement the deal, particularly in Iran, which has a long list of tasks to carry out under the JCPOA to limit the capacity of its nuclear programme before it can benefit from sanctions relief.

“The Iranians will be making certain their technical capabilities are up to scratch,” a western diplomat said. “But they’re not going to press the go button prematurely. They will [be] sure to figure out quickest, safest way to do the steps they have to under the agreement.”



The spectacle of the furious US political battle has also helped convince some sceptics in the Iranian leadership of the Obama administration’s determination to honour its side of the deal. Trita Parsi, the head of the National Iranian American Council, an advocacy group backing diplomacy with Tehran, said: “With the deal now being confirmed, there is a stronger expectation now that [Supreme Leader] Khamenei will come out and endorse it.”

Now that the deal has been secured in Washington, attention will shift to Tehran. President Hassan Rouhani argued that the JCPOA does not need approval from Iran’s parliament, the Majlis. The deal has been submitted for review, but ultimately nobody expects the Majlis to defy the supreme leader on such a crucial issue.

“Even the most ardent anti-American politicians in Tehran now realize that the US is no longer monolithically hostile towards Iran. What is less certain in their eyes is whether this amounts to a strategic shift or a ephemeral phenomenon that ends with Obama’s presidency,” Ali Vaez, an Iran expert at the International Crisis Group, said.



The real struggle in Iranian politics will be over whether the JCPOA will lead to a more general thaw in relations with the US. It has been a battle fought out in the past few days on the wall of the former US embassy, where the “Death to America” slogans that had been there since the 1979 Islamic revolution were painted over this week – only to be replaced by a plaque engraved with anti-American slogans put up by ultra-conservative students.

Conservative elements in the regime have been kept at bay by the Rouhani government, bolstered by the Obama administration’s success to date in keeping American hardliners in check. But that balance is precarious, as opponents of the JCPOA plan new unilateral sanctions aimed at sabotaging the agreement.



“Most worrying is that lobbyists have already begun circulating drafts for new legislation that would impose new waves of sanctions against Iran unilaterally without due regard for the conflict resolution process entailed under the deal,” said Ellie Geranmayeh, of the European Council on Foreign Relations.



“If such proposals become law in the course of the next few months when Iran begins to implement its commitments under the deal, Congress would in effect kill the agreement. Imposing US unilateral nuclear-related sanctions would force Iran to walk away from the deal; China and Russia are likely to do the same – and Europeans would be placed in a dilemma scenario.”

In his remarks on Wednesday, Kerry said he was prepared to work with Congress on sanctions “which are consistent with the agreement”. But the text on sanctions in the JCPOA explicitly notes: “Iran has stated that it will treat … such an imposition of new nuclear-related sanctions, as grounds to cease performing its commitments under this JCPOA in whole or in part.”

Therefore, new congressional sanctions, nuclear-related or otherwise, could still sink the agreement, and the US president could have to use his veto repeatedly to protect it, in turn raising concerns in Tehran and among US allies in Europe about the fate of the JCPOA after the Obama era comes to an end in January 2017.

Diplomats said that any disputes about new sanctions would hopefully be resolved by a joint commission including Iran and major powers, specially designated by the JCPOA as a means of conflict resolution.

Kelsey Davenport, the director for non-proliferation policy at the Arms Control Association, argued that prompt and complete Iranian compliance could have an effect on the continuing American debate. “Establishing a solid record of compliance will help thwart attempts to sabotage the agreement and demonstrate to US skeptics that Tehran is serious about restricting its nuclear program,” she said.
