Escalating Yemen Conflict Tests Saudi Defence Pacts
As Houthi forces secure key Red Sea ports, questions grow over why allied nations have not intervened despite formal treaties.
The strategic landscape of the Red Sea has shifted dramatically in the past two weeks, with Yemen’s Iran-aligned Houthis achieving their most significant territorial gains in years. According to reporting from GN auto geopolitics/middle-east: Yemen conflict, the militia captured the port of Mocha on September 10 and has since consolidated control over much of Yemen’s western coastline. This expansion places the group in a position to directly disrupt Saudi oil exports, a critical concern for Riyadh as global energy prices surge past $100 per barrel.
The escalation has raised sharp questions regarding the efficacy of Saudi Arabia’s recent defence agreements. Despite formal pacts with the United States, Pakistan, and Turkey, these allies have not deployed combat forces to the region. While Saudi Arabia has responded to Houthi missile attacks with airstrikes, the absence of broader military support highlights a disconnect between treaty commitments and operational reality on the ground.
Ambiguity in trilateral defence commitments
The Makkah Joint Defence Agreement, signed in August 2026, stipulates that an armed attack on any signatory is considered an attack on all. However, public details regarding the operational structure of this treaty remain scarce. Neither Pakistan nor Turkey has specified what constitutes a trigger for collective military response, nor have they outlined the escalation ladder that would obligate them to deploy troops. This lack of clarity allows both nations to maintain a diplomatic stance while avoiding direct combat involvement.
Turkish officials have noted that their parliament has not yet formally approved the defence treaty, further complicating any immediate military action. Meanwhile, Pakistan has emphasized that it stands ready to assist Saudi Arabia but has not defined the scope of that support. Defence Minister Khawaja Muhammad Asif stated that the agreement would be activated if territorial integrity is threatened, yet he declined to specify how that would be fulfilled against the Houthis, citing the need to keep strategic details confidential.
Diplomatic channels preferred over combat
Both Islamabad and Ankara are currently prioritizing diplomatic mediation over military intervention. Pakistan has reportedly engaged with Iran, the primary patron of the Houthi militia, urging them to restrain their allies. This approach reflects a broader regional strategy aimed at de-escalation rather than confrontation. By focusing on dialogue, these nations seek to prevent the conflict from spiraling into a wider regional war that could destabilize the entire Gulf area.
The reluctance to engage militarily also stems from the complex nature of the Houthi threat. While the group has targeted Saudi energy infrastructure, their primary objective appears to be political leverage within Yemen. For Pakistan and Turkey, intervening in a civil war with deep sectarian and geopolitical undercurrents poses significant risks to their own national interests. Consequently, both countries are maintaining a posture of conditional support, reserving the option of military aid for more extreme scenarios.
US restraint under prior understanding
The United States, despite its 2025 Strategic Defense Agreement with Saudi Arabia, has reportedly declined requests for direct military intervention. This stance is consistent with a 2025 understanding reached with the Houthis, in which the US ceased bombing campaigns in exchange for a commitment not to target American vessels. Although the Houthis are currently targeting Saudi ships, the US is wary of breaching this accord, which serves as a critical stabilizing factor in the Red Sea.
Washington faces a delicate balancing act. The Houthis possess the capability to disrupt global navigation in the Red Sea, a chokepoint vital for international trade. However, direct US military involvement could provoke a wider conflict with Iran and destabilize other parts of the Middle East. For now, the US is likely to continue monitoring the situation, providing intelligence and defensive support to Saudi Arabia without committing ground or air assets to offensive operations against Houthi positions.
