WASHINGTON — The Defense Department views increased partnerships between Arabian Gulf state allies as key to expanding security in the region, according to the Pentagon’s top international security adviser.

The Pentagon’s top priority is ensuring that “all have the capabilities that we agree they need to defend themselves,” Derek Chollet, the assistant secretary of defense for international security affairs, said at the DefenseOne conference in Washington Nov. 14. But to make that process happen, the Pentagon is focused on encouraging the sharing of military capabilities between allies.

“What we’re trying to do is help them all lift themselves up even more in terms of capabilities on the military side, but also to find ways that they can work more closely together,” Chollet said. “That’s often difficult, but it’s a project we’ve had some modest success on, and I think there’s enough to build on. That’s the biggest shift I would say over the last several years, the work to have them work together.
