The Three Musketeers pledged that an attack on one would be treated as an attack on all. Fiction gave them endless occasions to prove it. Treaties are rarely so obliging.

The newly signed Mecca Joint Defence Agreement between Saudi Arabia, Turkey and Pakistan borrows from the same language of solidarity. An armed attack on one signatory, it declares, will be regarded as an attack on all. Beyond that, the agreement says remarkably little. There are no explicit commitments, no operational framework, no NATO-style command structure.

On paper, it is a promise. In practice, its meaning remains deliberately open.

That ambiguity is precisely what makes the pact interesting. It is what allows three countries with very different threat maps—India for one, the PKK for another, Iran for the third—to sign the same document without promising each other anything specific.

The timing is no coincidence. Iranian missiles reaching Gulf energy infrastructure have shaken one of the oldest assumptions in West Asian security—that the American security umbrella is always open when it is needed. Saudi Arabia hosts American military assets, yet repeated attacks from Iran and the Houthis have raised uncomfortable questions about the reliability of that protection.

This is not the first defense understanding between Riyadh and Islamabad either. A bilateral pact already existed, yet Pakistan stopped well short of military intervention when Saudi Arabia came under attack. History suggests that these agreements are often more valuable as political signals than military guarantees. And that signal appears to be aimed less at Tehran than at Washington.

The agreement never mentions China; it does not have to.

Pakistan’s military is deeply intertwined with Beijing, relying on China for the overwhelming majority of its major defence imports. Turkey’s defence industry may look increasingly self-sufficient, but its sophisticated electronics and advanced weapons systems remain dependent on Chinese-controlled rare earth supply chains. At the same time, Ankara’s strategic drift toward BRICS, its engagement with the Shanghai Cooperation Organisation, and its role in linking the Belt and Road Initiative with the Middle Corridor all deepen China’s long-term stake in Turkish stability. Saudi Arabia, meanwhile, has quietly expanded its Chinese ties–buying armed drones and missile technology while Aramco invests billions in Chinese refineries. It is hedging on Beijing without abandoning Washington. Taken individually, these relationships are pragmatic. Viewed together, they begin to resemble something larger.

The Mecca agreement creates no formal Chinese alliance. Yet it quietly connects three countries whose strategic calculations increasingly intersect with Beijing’s interests. Every new layer of cooperation—whether in logistics, defense technology or regional diplomacy—widens China’s influence without requiring China to become a signatory. That may be the agreement’s most significant consequence.

The illustration draws on the image of the Three Musketeers. Three swords rise together, not to form a shield of their own, but to hold aloft an umbrella marked by a dragon. Above it circles an eagle—still present, still watching, but no longer certain where to perch.

Sometimes, the most revealing symbol in an alliance is not the people standing beneath it.

It is the hand that never appears, yet still holds the umbrella open.
