How Oman went from mediator to silent Saudi partner in Yemen fight

Oman has shifted from its traditional role as a neutral mediator in the Yemen conflict to becoming a silent partner of Saudi Arabia. Muscat provided intelligence and cooperated on military strikes against the UAE-backed Southern Transitional Council (STC) in Yemen’s al-Mahra region. This change was prompted by the STC's advance on Oman's border, raising concerns about a potential secessionist movement and evoking memories of the Dhofar insurgency. The joint Saudi-Omani action successfully countered the STC's advance, strengthening the relationship between Riyadh and Muscat.
