Even as the Donald Trump administration has struggled to rally the international community to respond to a series of alleged Iranian attacks in the Gulf that culminated in this month’s strike against a Saudi oil facility, the US is making another effort to forge a military alliance of Middle Eastern states.

Over the past several weeks, the State and Defense Departments have gathered a bloc of Gulf countries, including Saudi Arabia, the United Arab Emirates and Qatar, despite an ongoing blockade of Doha. Egypt exited the alliance last year.

In Washington last week, the Pentagon’s top Middle East policy official, Mick Mulroy, hosted the Middle East Strategic Alliance countries in an effort to organize the group’s security element, urging “whole of government cooperation across economic, security, energy and political spheres” in the wake of the Sept. 14 attacks on Saudi facilities at Abqaiq.

But after President Trump refused to retaliate against Iran after the Abqaiq strikes and the shootdown of a US drone, former US officials say that Gulf nations are becoming more wary of relying on the Pentagon for protection.
