The Mecca Defence Alliance faces its first practical test

The Mecca Defence Alliance, a new security pact between Saudi Arabia, Pakistan, and Türkiye, is facing its first major test amid escalating tensions with Houthi militias. The alliance has established an executive command and appointed a Pakistani general as its first secretary-general.
Why it matters
The formalization of this military bloc represents a significant shift in Middle Eastern and South Asian geopolitical power dynamics and regional security cooperation.
With almost a quarter of a billion people and a culture of healthy debate, there are not many topics in Pakistan that unite opinion, but Saudi Arabia is one. Whether from its political parties or from its 240 million people, there has been a rare and in many ways remarkable show of solidarity with Riyadh as its fight with the Houthi militia in Yemen escalated dramatically over recent weeks.
Together with Türkiye, the pair make up a triumvirate known as the Mecca Defence Alliance, which pledges mutual assistance if one of them is attacked. It was on this basis that the trio convened in an emergency session in Riyadh on 5 October, gathering foreign ministers, defence ministers, and top military commanders.
