Despite formal agreements and vast financial resources, Saudi Arabia has largely failed to integrate the various armed groups in Aden and southern Yemen under one national security sector. This adds to Riyadh’s ineffectiveness in establishing military-political influence in southern Yemen or in limiting the UAE’s continuing leverage. In an effort to boost its influence, since late 2022 Saudi Arabia has established new armed formations in Aden and nearby governorates, such as the Nation Shield Force.
