Research note: The report argues that the Mecca Joint Defense Agreement could grow into a regional deterrence structure by combining Türkiye's defense-industrial and operational capacity, Pakistan's military weight and Saudi financial resources. It is equally clear about what the pact does not yet have: a joint command, integrated planning or a defined mechanism showing how military assistance would be authorized and delivered after an attack.
Edited by Ayhan Sarı and written by eight contributors, the 77-page report draws on official documents, defense-capability assessments, trade and financial data, and reviews of Israeli and Arab media. It does not contain a standalone methodology section explaining how sources were selected or how the chapters were brought under a common research design.
Its economic chapter is among the strongest parts of the study. Rather than treating trade among the three members as the main payoff, it asks whether a functioning security arrangement could lower war-risk premiums, shipping costs and the price of disruption around Hormuz and the Red Sea. The focus is on logistics, transit, insurance and sustained maritime access.
Strategic relevance: The pact still has only the beginnings of an institutional structure. Ahead of the Aug. 31 Istanbul meeting, the first Strategic Political and Defence Committee session put implementation, political-military coordination and the emerging institutional structure on the agenda. The meeting produced a Riyadh-based secretariat under an initial Pakistani secretary-general and a commitment to deepen collective deterrence and defense cooperation.
Expansion is already being discussed. Foreign Minister Hakan Fidan identified Egypt as the clearest prospective additional member, while Pakistan has said the framework is open to states willing to accept its obligations.
The study's economic argument also intersects with the current Hormuz shipping and exclusion-zone file. If the pact is supposed to reduce regional risk, its credibility will depend on whether the three states can keep routes open, contain disruption costs and move personnel and equipment quickly enough when a crisis starts.
Bosphorus News reading: The report is less persuasive when it moves from Pakistan's possession of nuclear weapons to the claim that the other members effectively gain an extended nuclear guarantee. Its executive summary speaks of Pakistan giving the structure "nuclear depth," while another chapter describes the members' security as reinforced by a Pakistani nuclear guarantee.
The public agreement contains no nuclear clause. It commits the three countries to collective deterrence and says an armed attack on one will be regarded as an attack on all. Pakistan has described the accord as defensive and its operationalization as being at an early stage. Pakistan's nuclear arsenal is not in question. A Pakistani nuclear umbrella over Türkiye and Saudi Arabia is not established by the published agreement.
One passage also appears to merge separate historical episodes. The report says a 1998 India-Israel attempt against Pakistan's nuclear capability operated under the name "Operation Shakti" and was thwarted by Pakistani intelligence. Indian government records use Operation Shakti for India's own Pokhran-II nuclear tests in May 1998. Pakistan did warn that month of a possible Indian-Israeli strike on its nuclear facilities, an allegation Israel denied. Reports of joint Indian-Israeli planning against the Kahuta facility are generally associated with the early 1980s. The report does not establish a 1998 joint strike operation carrying the Operation Shakti name.
That does not undo its useful work on logistics, command arrangements or the economics of deterrence. It does mean the more expansive nuclear claims should be separated from what the agreement and public record actually establish.
The study is most useful as a measure of the distance between the pact's ambition and its present capacity. Its strongest contribution is not the nuclear-umbrella thesis, but the gaps it identifies in command, crisis decisions, maritime protection and sustained financing.
