What could the Mecca defence pact mean for the US role in the Middle East?

The pact, termed the Mecca Joint Defence Agreement, was signed in the Saudi city of Mecca on Friday.

“The agreement is intended to strengthen collective deterrence against any act of aggression, and stipulates that any armed attack against any one of the three states shall be regarded as an attack against them all,” a statement from the meeting reads.

“It further provides for the enhancement of all aspects of defence cooperation among the three states.”

While it is not yet clear what such an agreement might look like in practice, analysts say the pact points to growing questions about the durability of US security guarantees.

“Regional states have harbored growing doubts about the reliability of the US security partnership for more than a decade,” Kristian Coates Ulrichsen, a Middle East fellow at Rice University’s Baker Institute for Public Policy, told Al Jazeera over email.

“Both the decision to begin military operations against Iran and the subsequent conduct of the war and the on-off attempts to resolve it have only intensified those concerns and accelerated efforts to diversify security and defence relations.”

But, Ulrichsen added, building new defence pacts is likely not intended “to replace or supplant the US, but to provide additional strategic and policy options”.

While the administration of US President Donald Trump has yet to weigh in on the pact, analysts say the agreement is an effort by the three countries to reorient themselves after the turmoil of the Iran war.

“This is one of the first major geopolitical signs that the regional order is being reshaped by the US-Israeli war on Iran,” Sina Toossi, an analyst at the Center for International Policy, told Al Jazeera.

“The significance is less about a formal military alliance than about what it says regarding how regional states are reassessing security.”

Toossi pointed to the long-running alliance between the US and Saudi Arabia. For decades, the two countries have enjoyed a strong relationship, hinged on shared security interests. But the pact could be a sign that Saudi Arabia is looking to expand its security alliances.

“Rather than relying primarily on Washington, Saudi Arabia appears to be broadening its security partnerships and laying the groundwork for more intra-regional security arrangements,” Toossi explained. “That is arguably the most important takeaway.”

Media reports have also indicated that US partners in the Middle East were frustrated that the Trump administration had launched February’s war against Iran with little apparent thought to the impact on allies in the region.

Iranian forces have launched waves of missile and drone strikes against US military facilities in the Middle East, causing bystander casualties. Iran has also targeted civilian infrastructure, including energy and desalination plants.

Tehran’s decision to close the Strait of Hormuz, a key conduit for the region’s energy exports, has also imposed a steep cost on local economies.

Despite heavy strikes by the US and Israel, Iran has largely maintained its ability to restrict traffic through the strait, and Washington has struggled to provide partners with sufficient air defence munitions, many of which went to Israel.

Under the circumstances created by the war, the longstanding reliance on Washington for security in the region has become more strained.

“It’s a fluid, tabula rasa era in the Middle East,” Brett McGurk, a key architect of Middle East policy under former US President Joe Biden, wrote in a social media post.

But analysts note that Friday’s security pact is best understood as an effort to supplement regional security cooperation with other countries and deter Iran.

“These countries are all US partners, and they recognise that there is no framework that can replace the United States,” Yasmine Farouk, an analyst at the International Crisis Group, told Al Jazeera.

Farouk added that it would also be a mistake to see the pact as a step towards greater confrontation with Iran.

She noted that all three countries involved have generally called for mediation and de-escalation since the US and Israel first launched their attacks on Iran in late February.

“What these countries have in common is that they are not seeking regional escalation,” she said, underscoring that the importance of the agreement might be something closer to “normative deterrence”.

Iran, she explained, has emerged from the war hardened and more confident in its ability to use force to advance its goals.

“There is a long-term perspective here on strategic cooperation, not just a deterrent effect.”
