Introduction
On 7 August 2026, in a palace in Mecca, the leaders of Saudi Arabia, Turkey and Pakistan signed a defence pact declaring that an armed attack on any one of them would be treated as an attack on all three — language modelled deliberately on Article 5 of the NATO treaty. Three weeks later, Israel announced its single largest arms deal with a European state in years: a $3.5 billion agreement to help Greece build a multi-layer air-defence network called “Achilles Shield,” anchored by Rafael’s David’s Sling interceptor system, IAI’s Barak MX and a battery of surveillance radars. Israeli officials, Greek officials and most of the commentary that followed have framed these as separate stories — one a Middle Eastern realignment, the other a European rearmament decision shaped by the war in Ukraine and generic anxiety about Russia. Read side by side and in sequence, they look considerably more connected than that framing allows, and the connection runs directly through Ankara.
What actually got signed in Mecca
The Mecca Joint Defence Agreement, as it has since been formally named by its three signatories, did not appear from nowhere. It extends a bilateral Strategic Mutual Defence Agreement that Pakistan and Saudi Arabia signed in Riyadh in September 2025, adding Turkey to a collective-security arrangement at a moment when the region was already gripped by the wider war between the United States, Israel and Iran that had begun that February. On paper, the numbers are formidable: the three states together field close to 1.4 million active military personnel, some 3,400 aircraft, 6,000 tanks and more than 340 naval vessels according to the 2026 Global Firepower Index, and the grouping combines Turkey’s status as NATO’s second-largest army, Saudi Arabia’s oil wealth, and Pakistan’s position as the only nuclear-armed state in the Muslim world. Steven Cook of the Council on Foreign Relations called it a “major change” in Middle Eastern geopolitics and the first institutional security arrangement of its kind in the region; the Atlantic Council’s analysts were similarly struck by the symbolism, even while flagging how thin the substance underneath it still is.
That thinness matters and should not be glossed over. The text of the agreement has never been released. There is no joint command structure, no standing combined force, and no specified trigger mechanism for when the mutual-defence clause would actually be invoked — a gap that became visible almost immediately, when Pakistan and Turkey offered no military response after Saudi Arabia was struck by Iranian drones in the opening phase of the Iran war, despite the kingdom being a founding party to the pact. When officials from the three countries met again in Istanbul at the end of August to begin turning the political declaration into something operational, under a newly created Strategic Political and Defence Committee, they were candid that the institutional architecture — how the clause would actually function, who would decide when it applies — remains undefined. Analysts at the Arab Center in Washington have concluded that the pact’s political language carries more weight than its operational content, at least for now, with its more consequential near-term impact likely to run through defence-industrial cooperation rather than any actual collective-defence trigger: reports point to deepening the existing co-production of Baykar’s Akinci drone with Saudi Arabian Military Industries, and advanced Saudi-Turkish discussions over participation in Turkey’s Kaan fighter jet programme, both of which would help Riyadh toward its target of localising more than half its defence procurement spending by 2030.
None of that operational thinness, however, is the point from Athens’s perspective. A declaratory Article 5-style commitment between Turkey, a nuclear-armed Pakistan and an oil-rich Saudi Arabia does not need a functioning joint command to change how a neighbouring state calculates risk. It only needs to exist on paper, backed by three governments with genuine capability, to shift the baseline assumption against which Greece’s own defence planners size their air-defence requirements.
Why the timing lines up
Greek officials have publicly framed the Achilles Shield decision around lessons drawn from the war in Ukraine — the value of layered, combat-proven interception against drones, cruise missiles and long-range rockets in an era when high-intensity conflict has made air and missile defence look newly indispensable across NATO’s eastern flank. That framing is genuine, and it fits a pattern visible across the alliance generally. But it sits awkwardly with the specific timing and the specific systems Greece chose to acquire. David’s Sling, SPYDER and Barak MX are not primarily designed with Russian long-range ballistic missiles in mind; they are systems Israel developed and repeatedly combat-tested against exactly the mix of threats — short- and medium-range rockets, loitering munitions, drone swarms — that a state facing Turkey’s Aegean-based drone and stand-off strike capability would need most. Greece has already deployed Israeli-origin Drone Dome systems specifically to protect its Aegean islands from Turkish aerial threats, well before the Mecca pact existed. What the pact adds is not a new category of threat but a reason to treat the existing one as more urgent: Turkey’s drone and missile capability, expanding for years on its own trajectory, now sits inside a formal collective-security architecture that includes a nuclear weapons state, however incomplete that architecture’s institutional machinery remains.
That is also the more coherent explanation for why the Greece-Israel deal and the parallel push toward closer Greece-Cyprus-Israel security coordination — discussed at a trilateral summit in Jerusalem in December 2025 and revisited since — has accelerated specifically in 2026 rather than in any of the previous years when Aegean tensions were also high. Turkey’s capabilities were already growing before August; what changed is the alliance structure around Turkey, and a Greek government watching Ankara gain, at least on paper, the backing of a nuclear state and a wealthy Gulf patron has an obvious incentive to lock in its own countervailing partnership while Israel’s defence industry, flush with wartime orders and export reform, is actively looking for exactly this kind of long-term industrial relationship rather than one-off sales.
A market shifting east, not just toward Europe
It is worth correcting one assumption embedded in the standard account of Israel’s export boom, because the actual 2025 figures complicate it. Israel’s Ministry of Defence confirmed in June 2026 that total defence exports reached a record $19.2 billion for the year, up nearly 30 percent from $14.8 billion in 2024 — an unambiguous surge. But Europe’s share of that total actually fell, from 54 percent of all exports in 2024 to 36 percent in 2025, even as the value of European deals likely still grew in absolute terms given the size of the overall increase. What overtook it was Asia-Pacific demand, which very nearly doubled year on year, from about $3.4 billion to $6.1 billion, driven by countries seeking the same combat-tested missile and air-defence systems that are now anchoring the Greek deal. Europe remains, in absolute dollar terms, Israel’s largest single regional market, and the Greece and Finland deals are genuinely significant within it. But the narrative that European demand is what is “driving Israel’s export growth,” as is often assumed, understates how much of the recent surge is actually coming from buyers further east — a detail that matters for judging how central European goodwill really is to Israel’s defence-industrial strategy going forward, versus how replaceable any one European market might become if political relations sour.
The France counterexample, and why it is now more than friction
The Israel-France relationship supplies the clearest illustration of how far “friction” can travel before it becomes rupture, and the scale of that rupture by 2026 goes further than intermittent exhibition disputes. France barred Israeli firms from Eurosatory in 2024, only for a French commercial court to overturn the ban; Israeli companies were then blocked from the 2025 Paris Air Show after refusing to remove offensive-weapons displays, and Eurosatory 2026 saw a fourth restriction, this time confining Israeli exhibitors strictly to air- and missile-defence systems — a limitation Israel’s Defence Ministry called discriminatory and, in blunter Israeli commentary, “anti-Semitic.” What distinguishes 2026 from the earlier rounds is that Israel stopped merely protesting and reciprocated structurally: in April, Defence Ministry Director-General Amir Baram ordered a halt to all Israeli defence procurement from France, choosing to rely instead on domestic production and purchases from “friendly countries” rather than continue buying from a government it now regards as consistently hostile. That is a materially different posture from Spain’s 2025 contract cancellations or Italy’s 2026 decision not to renew certain agreements, both of which represent one side declining to buy or sell rather than a mutual severing of the relationship. France and Israel, on the 2026 evidence, are disengaging from each other’s defence-industrial base in both directions — which suggests the France relationship should be read less as a data point on a shared European spectrum of “friction” and more as a genuine outlier at the far end of it.
A sharper way to read the map
The standard account of Israel-Europe defence ties — deep cooperation persisting despite political friction over Gaza and settlements — is accurate as far as it goes, but it flattens a distinction that the 2026 evidence draws quite sharply. The states moving toward deeper, structural defence-industrial integration with Israel — Greece, Cyprus, Finland, and the Central and Eastern European buyers such as Romania, Serbia, Estonia, Slovakia and the Czech Republic — are disproportionately states with acute, specific, named threat perceptions: Turkey for Greece and Cyprus, Russia for Finland and the eastern flank states. The states moving toward restriction — France, Spain, Italy, the UK, the Netherlands, Norway — are, not coincidentally, states more geographically insulated from those particular threats and more exposed to domestic political and legal pressure generated by the war in Gaza and the West Bank. The Mecca pact does not create that divide, but it sharpens it considerably for one specific pair of states, by handing Ankara a formal, if still institutionally hollow, collective-security architecture that includes a nuclear-armed partner — and by doing so just weeks before Greece signed the largest Israeli arms deal in years. Reading that sequence as coincidence requires ignoring exactly the kind of alliance-politics logic that has driven Israeli-European defence cooperation for decades: partners buy from Israel not because they have resolved their political disagreements with Jerusalem, but because a specific, named threat has just become more concrete than the disagreement.
What would actually test this reading
If threat-specificity really is the variable doing the work here, rather than a generic split between “pragmatic” and “principled” European capitals, a few things should follow over the next year or two. Finland’s extension of cooperation through 2034, and its reported involvement in roughly twenty separate defence projects with Israeli firms, should keep deepening regardless of how the Gaza conflict’s diplomatic fallout evolves, because Helsinki’s calculus is anchored to its border with Russia rather than to any view of the Middle East. Greece and Cyprus’s trilateral coordination with Israel should continue to outpace whatever domestic political friction exists in Athens — where persistent public criticism of Israel’s conduct in Gaza remains real, and where a 2027 electoral cycle could yet complicate the pace of formal trilateralisation — precisely because the Turkish variable does not go away regardless of who governs Greece. And the Mecca pact itself should be watched less for whether it produces genuine collective military action, which its current design makes unlikely, than for whether its defence-industrial track — Baykar-SAMI drone co-production, the Kaan fighter jet talks — actually matures into the kind of localisation Riyadh wants by 2030, because that would represent Turkey and its new partners building an alternative supply chain to the Western and Israeli one, rather than merely declaring solidarity against a shared external threat. Should that industrial track advance, the countries currently deepening ties with Israel over Turkish-linked threat perceptions would have even more reason to entrench those partnerships rather than reconsider them — a self-reinforcing dynamic that the standard “friction versus pragmatism” framing, focused as it is on Gaza-related political sentiment, is not well equipped to anticipate.
