Mecca Joint Defense

A Saudi-led initiative for collective defense and counterterrorism cooperation in the Islamic world, with Mecca as its symbolic center.

Mecca Joint Defense

Overview

Mecca Joint Defense (메카 공동방위) is an initiative that places Mecca, the holiest site in Islam, at the symbolic and geographic center of security and seeks to institutionalize collective defense and counterterrorism cooperation among Islamic countries under Saudi Arabian leadership. The discussions took concrete shape through the establishment of the Islamic Military Counter Terrorism Coalition (IMCTC) in 2015 and the Mecca Declaration in 2019, and it became a key axis in reshaping the Gulf regional security order in response to threats from the Houthi rebels in Yemen and Iran. However, the prevailing assessment is that conflicts of interest among participating countries and the absence of a permanent command structure have prevented it from reaching the stage of a substantive collective defense treaty.

Key Details

Background: Security of the Holy Sites and the Legitimacy of the Monarchy

Mecca and Medina are areas that draw millions of pilgrims annually, and maintaining security there is directly linked to the religious legitimacy of the Saudi monarchy. The 1979 Grand Mosque seizure and the 1987 Mecca pilgrimage clashes are cases showing that a failure to secure the holy sites can immediately lead to a regime crisis. Accordingly, Saudi Arabia chose a strategy of drawing military cooperation from the entire Islamic world under the cause of defending the holy sites, and this became the starting point of the Mecca Joint Defense discourse.

Relationship with the Islamic Military Counter Terrorism Coalition (IMCTC)

In December 2015, an Islamic military alliance involving 34 countries was announced in Riyadh, and the name was later finalized as the Islamic Military Counter Terrorism Coalition, with its secretariat located in Riyadh. The Mecca Joint Defense initiative is understood as an attempt to elevate this coalition beyond a simple counterterrorism network into an alliance with a collective defense clause. In fact, at the time of its founding, the Saudi side raised the need for a clause treating an attack on one member state as an attack on all, but it could not be codified due to opposition from many member states.

Points of Contact with the Gulf Cooperation Council (GCC) Defense System

Since its founding in 1981, the GCC has operated a joint force called Peninsula Shield, but it suffered a blow to its credibility when it failed to respond substantively during Iraq's invasion of Kuwait in 1990. The 2017 Qatar diplomatic crisis exposed rifts among member states, and this became the background for pushing the Mecca Joint Defense initiative as a separate track to replace or complement the GCC.

Participating Countries and Military Composition

Saudi Arabia, the United Arab Emirates, Egypt, Jordan, Pakistan, Turkey, and others are mentioned as core participating countries, while non-Arab Islamic countries such as Malaysia, Indonesia, and Nigeria are also partly involved. Militarily, discussions include a plan for an integrated command headquartered in Riyadh, an intelligence-sharing platform among member states, joint special operations and explosive ordnance disposal training, and operations for maritime blockade and protection of navigation through the Strait of Hormuz. Saudi Arabia's advanced air defense network, the UAE's air power, and Pakistan's ground force personnel are assessed as complementary assets.

Financial and Logistics Support Structure

A division-of-labor structure is characteristic: Saudi Arabia and the UAE bear a significant portion of the funding, while countries with relatively weaker military power but larger populations provide troops. This structure is criticized both as a means of exercising political influence over beneficiary countries and for creating human rights and control problems in the militaries of vulnerable states.

Controversies and Limitations

First, the biggest weakness is that Iran cannot be designated as an explicit enemy state. As long as it claims Islamic solidarity, it is difficult to exclude a Shia state. Second, many member states have separate security relationships with India, the United States, and others, creating a dual alliance problem. Third, as controversy over civilian casualties caused by the Saudi-led coalition in the Yemeni civil war grew, the alliance's moral legitimacy weakened. Fourth, because there is no permanent command, joint budget, or mandatory participation clause, automatic intervention in an actual crisis is difficult to expect.

Recent Trends

In March 2023, as Saudi Arabia and Iran agreed to normalize relations through Chinese mediation, the anti-Iran character of Mecca Joint Defense was partly diluted. Instead, the alliance's center of gravity shifted toward protecting Red Sea shipping lanes and responding to drone and missile threats from the Houthi rebels. After 2024, attacks on commercial vessels in the Red Sea continued, increasing the need for multinational maritime defense, and Saudi Arabia maintained a cautious attitude by separating the defense of its own territory from maritime operations.

In 2024–2025, as public opinion in the Islamic world intensified due to the prolonged Gaza war, what stance the Islamic military alliance would take toward Israel emerged as a new test. However, most participating countries are in a position where they must maintain security cooperation with the United States, so they are passive about turning the alliance into an anti-Israel military bloc. In addition, as easing regional tensions is prioritized for the implementation of Saudi Vision 2030, the trend is for joint defense to be reorganized around institutional improvement and intelligence and defense industry cooperation rather than expansion. Joint development projects aimed at Gulf defense industry self-reliance and the integration of drone and air defense systems are an extension of this trend.

In conclusion, Mecca Joint Defense can be defined not as a completed military alliance but as an evolving project that seeks to secure Saudi Arabia's centrality in the Islamic world's security order by leveraging the symbolism of the holy sites.
