Türkiye's parliament ratifies Mecca defense pact with Saudi Arabia and Pakistan
Türkiye's parliament on Thursday ratified the Mecca Joint Defense Agreement with Saudi Arabia and Pakistan by 279 votes to 119, Al Jazeera reports, citing AFP and Reuters. The 10-year pact's collective-defense clauses commit the parties to assist one another if any is attacked, language observers compare to NATO's Article 5; it also deepens defense-industry and intelligence cooperation. Ankara signed in August as Saudi Arabia faces renewed Houthi strikes; Turkish officials say the aim is deterrence, not an automatic war with the Houthis, while critics ask how the pact sits beside Türkiye's NATO duties.

The Holy League before Lepanto
What happened then
In 1571 Pope Pius V brokered a Holy League whose core members were Spain, Venice and the Papal States, joined by other Italian powers and the Knights of Malta, to check Ottoman naval power in the eastern Mediterranean after the fall of Cyprus.
What caused it
Ottoman expansion and the loss of Venetian strongholds made separate Christian states look vulnerable; religious appeal and hard interest combined to produce a temporary coalition with a shared fleet command under Don John of Austria.
How it was resolved
On 7 October 1571 the allied fleet defeated the Ottoman navy in the Gulf of Patras near Lepanto. The victory was celebrated across Catholic Europe as providential, even though the League itself soon frayed and Ottoman power on land endured.
How it turned out
Lepanto showed both the strength and the limits of faith-framed mutual defense: it could unite rivals for a season and decide a battle, yet it did not end the deeper contest. Modern collective-defense pacts still wrestle with the same questions of solidarity, free-riding and entanglement.
What the philosophers say
In The Law of Nations, Vattel treated treaties of alliance as instruments of mutual security under the law of nature, binding because nations, like persons, must be able to trust promises. He insisted that alliances may be contracted across religious lines — peoples treat as nations, not as sects — and that offensive pacts for plunder are void, while defensive aid against unjust attack is legitimate. He also warned that a sovereign already bound cannot validly promise what would destroy prior duties. That frame fits a new collective-defense pact beside an older alliance system: the moral test is whether the promise is truly defensive, honest to existing obligations, and kept — not whether the signatories share a creed.
