Saudi Arabia united the Arab world against Iran. That means conflict could be one step closer

Jeddah, Saudi Arabia (CNN)King Salman of Saudi Arabia has pulled off in Mecca what many had thought unlikely — getting 20 or so disparate Arab nations to unite in a common position against Iran.
And while this achievement came without bellicose threats or new red lines, it is an important milepost on a road that may yet lead to regional conflict.
In middle-of-night, back-to-back summits at Islam’s holiest of sites, the aging but still-attentive Saudi monarch got a double endorsement of his claims that Iran is destabilizing the Middle East and a backing of his call for “the international community to shoulder its responsibility. The six-nation Gulf Cooperation Council and 21 Arab League nations present called for Iran to stop “interfering in the internal affairs” of its neighbors and denounced Tehran’s “threat to maritime security” in the Persian Gulf. For its part, Iran hit back, criticizing the allegations as “baseless” and accusing Saudi Arabia of promoting an “American and Zionist” agenda. Still, Tehran appeared tone-deaf to not one, but two unifying summit communiques urging it to change its behavior.

US pressure was applied to get Qatar to send a high-level delegation to the summits. When the country’s prime minister, Sheikh Abdullah bin Nasser al-Thani, showed up, he was the only leader not to get a customary kiss from the King. While he didn’t get much eye contact from some of the leaders gathered around the GCC table, al-Thani did back the Saudi monarch, saying: “Our participation comes from our support to join Arab and Islamic work and our common security and stability.” It marked the sign of a possible thaw in relations, but also the reemergence of Saudi Arabia from pariah to regional power broker again, which is good timing for its key ally, US President Donald Trump, as he doubles down on sanctions and pressure on Iran.. King Salman himself admitted that “failure to take a firm position against the Iranian regime” in the past had “led to the escalation we see today.”
What we saw in Mecca was a mark being set, that the status quo with Iran will no longer be tolerated by Saudi and its allies. What happens next is in Iran’s court. Talks are an option, but terrorism, insofar as it is perceived as such by Tehran’s neighbors, is not.
