NATO member states have shown no inclination toward collective or unilateral ground deployments in Yemen, with recent escalations instead prompting limited defensive assistance to Saudi Arabia under bilateral or trilateral arrangements. The October 2026 launch of Yemen's government offensive near the Bab al-Mandeb Strait drew Saudi airstrikes and support from Turkey and Pakistan via their Mecca defense pact, yet Turkish officials explicitly ruled out sending forces into Yemeni territory for combat. The United States has supplied intelligence and refueling while rejecting direct strikes, and the United Kingdom has offered similar defensive refueling, consistent with NATO's focus on European deterrence rather than Middle East expeditionary operations. This pattern of restraint sustains the 95.6% implied probability against NATO troops fighting in Yemen before 2027, though a sharp regional escalation involving alliance-wide threats to shipping or allies could still prompt reconsideration.
