The war in Yemen is spinning out of control again. If you look at the map right now, Iran-aligned Houthi forces are pushing hard toward the critical Bab al-Mandab strait, threatening global shipping lanes and Saudi oil infrastructure. Riyadh is sweating.
Yet, instead of a united front, the two primary powers driving the anti-Houthi coalition—Saudi Arabia and the United Arab Emirates—spent much of this year working at cross-purposes. Back in January, tensions exploded into the open when Saudi forces confronted and defeated a major UAE-backed separatist force, the Southern Transitional Council (STC), effectively driving the Emirates out of active military coordination in Yemen.
Now, international pressure is mounting. Washington, regional diplomats, and strategic analysts are telling Riyadh straight: you cannot push back the Houthis without burying the hatchet with Abu Dhabi and bringing UAE-trained southern forces back into the fold. But doing that is easier said than done.
The Cost of Deep-Seated Regional Fractures
You can't understand the current military collapse in southern Yemen without looking at the fundamental split between Saudi and Emirati goals. Riyadh wants a unified Yemen under the internationally recognized government, fearing that any partition of the country will leave a hostile, heavily armed Houthi mini-state right on its southern border.
Abu Dhabi took a different bet early on, heavily backing southern separatists who want to revive an independent south. When Saudi forces moved to crush the STC in January to squash that independence bid, the partnership fractured. The UAE pulled back its direct military footprint, leaving anti-Houthi defenses vulnerable.
That vulnerability turned into an operational disaster in September. Houthi fighters swept south, shattering pro-government positions, including the National Resistance Forces led by Tareq Saleh. Now, Houthi units are trying to smash their way into Taiz while hammering the vital Red Sea chokepoints.
Can the Giants Brigades Save the Day?
Out on the frontlines, everyone knows the most reliable, battle-hardened ground forces capable of stopping the Houthi advance are the Giant Brigades—southern troops trained and equipped by the UAE.
There is just one massive catch. The STC and southern leaders are telling these brigades not to merge fully with the Riyadh-backed government army unless they get a genuine political guarantee regarding self-determination. Khaled Alyemany, a former Yemeni foreign minister and supporter of the southern cause, pointed out the obvious flaw in the current setup. If southern fighters are expected to bleed and die to retake Sana'a for a government that refuses to discuss independence, they aren't going to give it their all.
As long as the UN-recognized government derives its legitimacy entirely from Saudi checks rather than popular local support, military cohesion remains an illusion.
The Diplomatic Scramble and External Players
Behind closed doors, frantic diplomatic maneuvers are underway. Recently in Abu Dhabi, leaders met to hash out a path forward, featuring high-level representation from Gulf states, regional players, and international figures. Rumors even swirled of unconventional intelligence-sharing proposals involving private security or external tech, though Riyadh historically balks at anything that looks too close for comfort.
Meanwhile, Prince Khalid bin Salman, the Saudi defense minister, sat down in Riyadh with UAE Vice President Mansour bin Zayed Al Nahyan to test the waters of reconciliation. Both sides know they have mutual interests in energy security and regional stability, but bridging the Yemen gap requires hard compromises.
The Houthis are watching this internal friction and smelling blood. According to data from the World Health Organization, hundreds have been killed and thousands injured in the latest surge of violence. Independent analysts note that the Houthis view the current fight as an existential contest where they hold the momentum, expecting Riyadh to seek de-g escalation under pressure just as it has done in past rounds with Iran.
What Happens Next on the Ground
Saudi Arabia's parliament has sanctioned a general mobilization of the population to block the Houthi consolidation. But empty appeals for volunteer mobilization won't stop disciplined, drone-equipped insurgent forces without heavy armor, air cover, and unified command structures.
If Riyadh wants to keep its energy installations safe from persistent drone and missile attacks, it has to decide what matters more: preventing southern separation or surviving the Houthi onslaught. Reconciling with the UAE means swallowing pride, opening the door for the Giant Brigades to fight effectively, and giving southern politicians a seat at the table.
Time is running out. Either the Gulf powerhouses learn to share the chess board, or the Houthis will write the final chapter of the war on their own terms.
