Riyadh. Saudi Arabia and its Gulf allies basked on Wednesday (09/05) in what they saw as a political victory over Iran, their rival for regional influence, after Washington withdrew from the international nuclear accord with Tehran.

Saudi Arabia, the United Arab Emirates (UAE) and Bahrain swiftly backed US President Donald Trump's decision to reimpose sanctions on Tehran, reflecting their concern about Iran's ballistic missile program and support for militant groups.

"Paris and London may not like Trump's decision, but how would the French or British feel if their capital cities came under direct threat by the Iranians?" editor-in-chief Faisal Abbas wrote in Saudi Arabia's English-language Arab News daily next to a headline that read: "The deal is dead."

In a coffee shop, Saudi businessman Ziad said the kingdom's leadership was correct to challenge a deal that had eased sanctions in exchange for Tehran taking measures that would prevent it being able to make a nuclear weapon.

"Every couple of days, we have missiles coming from Yemen and we see evidence that they are made by Iran ... It is interfering in Syria, Yemen, Morocco. Other countries may accept that, but here in Saudi Arabia we don't," he said.

An hour later, at least four loud blasts rocked Riyadh. Authorities said they had intercepted two ballistic missiles fired from Yemen, where a Saudi-led coalition is fighting to oust the Iran-aligned Houthi movement from the capital and large parts of the country.

Proxy Wars

The Sunni Muslim kingdom has been at loggerheads with Shi'ite Iran for decades, fighting a long-running proxy war in the Middle East and beyond that has influenced conflicts in Iraq, Syria, Lebanon and Yemen.

The Saudi Foreign Ministry accused Iran of using economic gains from the lifting of sanctions to develop ballistic missiles and support militants. It called for a "comprehensive view that is not limited to its nuclear program but also includes all hostile activities."

Anwar Gargash, UAE Minister of State for Foreign Affairs, tweeted that Iran had been emboldened by the nuclear deal, and "its ballistic missile program became both offensive & exportable."

Trump has employed similar arguments, criticizing the accord for failing to address Iran’s ballistic missile program, its nuclear activities beyond 2025, or its role in regional wars.

"He is supporting us not because we are Saudi Arabia or because we have oil, but because he thinks we are right," said Mohammed, another Saudi businessman.

Oman, which orchestrated secret US-Iran contacts that helped pave the way for the deal in 2015, was more measured.

"We believe the United States and the Islamic Republic of Iran are interested in realizing peace and stability in the region, and the choice of confrontation is not in the interest of either side," its foreign ministry said.

Kuwait said in a statement that it "understands and respects" Trump's decision.

Qatar, locked in a dispute with Saudi Arabia and other Arab states, meanwhile cautioned against a potential nuclear arms race in the region.

"It is in the interest of all parties to exercise restraint, wisdom and patience and to try to resolve differences through dialogue," its foreign ministry said.

Saudi Arabia, the UAE, Bahrain and Egypt imposed a trade and transport boycott on Qatar in June, accusing it of financing militant groups and cozying up to Iran -- charges it denies.

'Sinister Activities'

"The Omani, Qatari, and Kuwaiti governments have all sought to maintain pragmatic relations — economic more than political — with Iran," said Kristian Coates Ulrichsen from the Texas-based Rice University's Baker Institute.

"There is likely to be a feeling of jubilation in Riyadh and Abu Dhabi that the Trump administration — or at least the White House — has now come round to their thinking on Iran's threat to regional security."

In his speech on Tuesday, Trump condemned Iran's "sinister activities" including backing armed Islamist groups such as Hezbollah in Lebanon and Hamas in the Palestinian Gaza Strip.

Abdulaziz al-Sager, head of the Jeddah-based Gulf Research Centre, said the message was significant in that it reflected Gulf concerns. "We've always said our concern about this agreement in 2015 was that Iran should not take it as 'carte blanche' to go and expand its territorial influence."

Saudi Crown Prince Mohammed bin Salman, who serves as Saudi defense minister, told CBS News in March that his country would "without a doubt" develop nuclear weapons if Iran did so.

Iran had ruled out renegotiating the accord and threatened to retaliate if Washington withdrew.

It could do so by undermining the interests of Washington and its allies in the Middle East, perhaps by increasing support for Yemen's Houthis. The Saudi Arabia and Emirati forces fighting the Houthis both receive military backing from the United States and other Western allies.

"There is a real risk of escalation, especially between Iran and Israel. While the Gulf states may want to see the US and Israel try to cut Iran to size, I don't think they want to get dragged into a direct confrontation themselves. The consequences could be severe," said Joost Hiltermann, program director, Middle East and North Africa at the International Crisis Group.
