The Saudi-UAE proxy war in Yemen

The Saudi-UAE proxy war in Yemen

Force in Play

Former coalition partners clash over southern separatists and regional power

January 10th, 2026: Supreme Military Committee Formed Under Saudi Command

Overview

Two former allies just fought a proxy war in Yemen—against each other. Saudi Arabia bombed a UAE arms shipment in January 2026 after UAE-backed separatists seized Aden and Yemen's oil fields. Within a week, Saudi-backed forces crushed the rebellion, forcing the separatist leader to flee. The STC announced dissolution on January 9, but immediately rejected its own announcement, exposing deep fractures between members in Riyadh and those loyal to Abu Dhabi.

What started as a joint intervention against Houthi rebels in 2015 has fractured into a power struggle over Yemen's future. Saudi Arabia wants territorial integrity on its southern border. The UAE wants southern independence to expand influence from the Horn of Africa to the Red Sea. Even after military defeat, thousands rallied in Aden on January 10 waving South Yemen flags, proving the separatist dream survives despite losing every battle.

Historical Context

1994 Yemen Civil War: Southern Secession Crushed

May-July 1994

What Happened

Four years after unification, southern Vice President Ali Salem al-Beidh declared independence as the Democratic Republic of Yemen, citing northern domination and appropriation of southern oil resources. No country recognized the breakaway state. Northern forces captured Aden within two months, crushing the secession and forcing southern leaders into exile.

Outcome

Short Term

Northern Yemen established military dominance, reduced southern representation in parliament, and abolished power-sharing arrangements.

Long Term

The defeat created lasting grievances that fueled the Southern Movement and eventually the STC. Many 1994 fighters, including al-Zubaidi, became 2017 separatist leaders.

Why It's Relevant Today

The 2026 STC collapse mirrors 1994: a southern independence bid crushed by superior forces, leaders fleeing to exile, and separatist dreams deferred but not extinguished.

Saudi-Qatar Crisis 2017-2021: Gulf Alliance Fractures

June 2017 - January 2021

What Happened

Saudi Arabia, UAE, Egypt, and Bahrain severed ties with Qatar, imposing a land, air, and sea blockade over allegations of supporting terrorism and ties to Iran. The quartet demanded Qatar close Al Jazeera, shut down a Turkish military base, and align foreign policy with Saudi/UAE positions. Qatar refused all demands. The U.S. attempted mediation while maintaining military ties with all parties.

Outcome

Short Term

Qatar deepened relationships with Turkey and Iran, undermining the blockade. Kuwait and Oman remained neutral, exposing GCC disunity.

Long Term

The crisis ended in January 2021 with Saudi-Qatar reconciliation, but UAE remained distant from Doha. The blockade demonstrated Gulf states could pursue divergent regional strategies.

Why It's Relevant Today

The Qatar crisis showed Gulf unity is fragile and UAE-Saudi interests can sharply diverge. The 2026 Yemen clash suggests an even deeper rift, as the two largest Gulf powers now back opposing forces in armed conflict.

Soviet-Afghan War: Proxy Turned Enemy

1979-1989

What Happened

The U.S. and Saudi Arabia funded mujahideen fighters to resist Soviet occupation of Afghanistan, funneling billions through Pakistan's intelligence services. The coalition succeeded in forcing Soviet withdrawal in 1989. However, the power vacuum and lack of post-war planning led to civil war, eventually bringing the Taliban to power and providing safe haven for al-Qaeda.

Outcome

Short Term

Soviet defeat represented a major Cold War victory for Western and Gulf state sponsors of the resistance.

Long Term

Former CIA-backed fighters turned against their sponsors. The Taliban harbored terrorists who attacked the U.S. on 9/11, leading to two decades of American military presence.

Why It's Relevant Today

Yemen illustrates similar risks when regional powers create proxy forces without exit strategies. The UAE built the STC as an anti-Houthi proxy, but the separatists pursued independence, threatening Saudi interests and turning allies into adversaries.
