The Middle Eastern Cold War: Two Blocs, One Iron Curtain

The Strait of Hormuz has closed without a formal declaration. Iran accomplished this not with minefields but with a calibrated campaign of missile and drone strikes that collapsed commercial transit volumes by 90 percent according to RUSI tracking. The vessels that still pass navigate under Iranian supervision along prescribed corridors. Roughly 60 percent of residual traffic is Iranian-flagged or tied to Iranian commercial networks. The world’s most critical petroleum corridor now operates under de facto Iranian management.

That is the backdrop. The story is something else.

A structural realignment has produced two coalitions across the Middle East. Turkey, Saudi Arabia, and Pakistan form a northern arc. Israel and the UAE form a southern axis. The old Sunni-Shia frame does not explain it. The Iran-centric frame does not explain it. Turkey wants a unified Syria under a Sunni-led government aligned with Ankara; Israel wants a fragmented Syria where Iranian land corridors to Hezbollah are permanently severed. These objectives are mutually exclusive — Turkey needs Assad gone, Israel needs Iranian supply lines cut regardless of who holds Damascus. Syria is the primary theater of the Israel-Turkey cold war: Israel conducts 200+ annual strikes on Iranian and Hezbollah targets in Syria per ISW, while Turkey occupies northern Syria (Idlib, Afrin, Ras al-Ayn) and backs SNA factions that occasionally clash with SDF/US partners Israel quietly supports.

At the same time a new Iron Curtain descends from the Arctic through the Baltic states, Belarus, Ukraine (the Donbass/Crimea line), the Black Sea, the Caucasus (Georgia’s frozen conflicts, Armenia’s CSTO trap), the Caspian, into Central Asia — a continuous Russian security perimeter that NATO expansion (Finland 2023, Sweden 2024) has extended by 1,300 km of direct border. The Middle Eastern cold war and the Iron Curtain are not separate systems. They intersect at the chokepoints. They share the same great-power anchors. The Caspian has become a contact line between wars.

Ankara-Riyadh-Islamabad: The Northern Tier Reassembled

In February 2024 Turkey and Saudi Arabia signed a defense cooperation framework at the World Defense Show in Riyadh. The agreement included Bayraktar TB2 drone technology transfer and joint production talks. Saudi Arabia has since expressed interest in procuring Turkish Bayraktar Akinci and Kizilelma drones; negotiations reported in 2024-2025 point to a potential deal worth over 3 billion dollars. Erdogan visited Pakistan in 2024 and Azerbaijan in 2023, signing defense MOUs that include Turkish-Pakistani joint production of next-generation fighter components and Azerbaijani integration into Turkish drone supply chains.

Pakistan and Turkey are co-developing the MILGEM-class corvette for Pakistan Navy (four ships planned, the first commissioned in 2023) alongside joint naval exercises (TURGUTREIS, AMAN) and Turkish TF-X fighter participation discussions. Pakistan, Turkey, and Azerbaijan conducted trilateral military exercises (Three Brothers) in 2021, 2023, and 2024, institutionalizing a security coordination format that includes intelligence sharing and joint procurement planning. The Saudi-Pakistan-Turkey defense triangle is operational: Saudi Arabia funds, Pakistan provides manpower and a nuclear umbrella, Turkey provides drones and naval platforms. The 2024 Moscow defense show featured Bayraktar TB2/Akinci displays for Saudi procurement teams alongside Pakistani JF-17 Block 3 and Turkish TF-X mockups.

Pakistan’s TF-X (Kaan) participation discussions with Turkish Aerospace Industries would give Islamabad a fifth-generation pathway independent of Chinese J-35/FC-31 or American F-35 denial. Pakistan Aeronautical Complex already co-produces MILGEM corvettes and hosts Turkish engineers for drone assembly. India-China border clashes (Galwan 2020, Tawang 2022) pushed New Delhi toward Israel-UAE security cooperation while Pakistan-China military integration (J-10C, HQ-9B, Gwadar naval base) deepens; the subcontinent rivalry now maps onto the Middle Eastern cold war. India’s IMEC participation directly counters China’s BRI and Pakistani Gwadar port; Modi’s government has deepened defense ties with Israel (Barak-8, Heron drones, Spike ATGMs) and UAE (strategic partnership 2022) while maintaining strategic autonomy via SCO/BRICS membership and Russian S-400/oil imports.

Jerusalem-Abu Dhabi: The Abraham Architecture

The Israel-UAE axis runs through economic-security fusion. The India-Middle East-Europe Economic Corridor announced at the G20 in 2023 links India, UAE, Saudi Arabia, and India through maritime trade routes — explicitly bypassing Iranian chokepoints (Hormuz, Bab el-Mandeb) and Turkish-controlled straits. Israeli naval deployments to the Red Sea operate in coordination with UAE bases. Rafael-UAE joint ventures on SPYDER air defense and Elbit Systems UAE partnerships create a defense-industrial layer beneath the diplomatic one. The Abraham Accords were framed as normalization. They are functioning as coalition-building.

The UAE has provided financial and material support to the Sudanese Armed Forces (SAF) under al-Burhan since the April 2023 war outbreak, including drone shipments (Wing Loong II variants) and gold-for-arms deals via Abu Dhabi-linked firms, per UN Panel of Experts reports. The UAE backs the Southern Transitional Council (STC) in Yemen with training, funding, and Emirati-run security belts in Aden and Socotra, creating a parallel southern security structure independent of the internationally recognized Hadi/PLC government. The UAE recognized Somaliland in January 2024 via a MoU granting Ethiopia naval access to Berbera in exchange for Somaliland recognition, aligning with Israel which has maintained covert security ties with Hargeisa since the 1990s including reported Mossad presence and Berbera port intelligence sharing.

Morocco normalized relations with Israel in December 2020 (US recognition of Western Sahara sovereignty as quid pro quo); Rabat now hosts Israeli liaison offices, purchases Barak MX air defense and Skylark drones, and coordinates maritime surveillance in the Strait of Gibraltar — a NATO chokepoint. Morocco’s Western Sahara autonomy plan aligns with the Israel-UAE axis: both oppose Turkish-backed Islamist movements in the Sahel and both view Iranian influence in West Africa (via Hezbollah fundraising networks) as a shared threat.

The Maritime Front: Bab el-Mandeb, Hormuz, Caspian

The battlefield is the water.

At Bab el-Mandeb the Houthi blockade of Saudi ports imposed on July 20 2026 forced at least seven vessels to divert. The Institute for the Study of War and Critical Threats Project tracked attacks on two Saudi oil tankers two days later. The US-UK-Israeli-UAE response coordinates maritime domain awareness. Turkey refused to join Operation Prosperity Guardian. Saudi Arabia limited its participation to diplomatic statements.

At Hormuz Iran has introduced a model where access depends on political alignment. The Persian Gulf Strait Authority requires permission and charges fees up to two million dollars per passage. Ships linked to Russia, China, India, and Pakistan move. The rest wait or reroute around the Cape of Good Hope.

In the Caspian Sea Ukrainian drone strikes in July 2026 hit the Molnyia, Port Olya 2, and Begey. RFE/RL reported the targets as vessels ferrying military cargo between Iran and Russia. Tehran said one sailor was killed and summoned Ukraine’s charge d’affaires. ISW assessed this as a direct escalation in the Russia-Iran-Ukraine war fusion. The Iranian vessel Ana (IMO 8934491) was among the vessels struck according to Ukrainian intelligence though registered sources verified report the Molnyia, Port Olya 2, and Begey instead.

Russia-Iran trade volumes rose 40 percent from 2022 to 2024 according to Russian customs data. Russia absorbed Iranian tanker capacity via its shadow fleet. The shadow fleet now operates with its own flags, its own insurers, and its own naval coordination.

Several Baltic Sea undersea infrastructure elements including the Balticconnector gas pipeline, Estlink 2 power cable, and fiber-optic cables between Lithuania-Sweden and Finland-Germany were damaged between October 2023 and December 2024. Russia had both capability and incentive to use maritime assets to probe or sabotage critical seabed infrastructure.

Russia and Iran signed a 20-year comprehensive strategic partnership in January 2025. The agreement deepens military-technical cooperation including Su-35 deliveries, air defense integration, and Caspian Sea naval coordination that directly enables Iranian drone production used against Ukraine and Gulf targets.

Moscow-Tehran: The Enabler Behind Both Curtains

The external power makes both regional axes possible. Russia supplies the advanced air frames (Su-35). Iran supplies the drone volume (Shahed). The Caspian becomes a contact line between wars. Iran and Russia’s 20-year strategic partnership includes Caspian naval coordination, North-South Transport Corridor (Astara-Rasht-Qazvin rail), and joint sanctions evasion — linking the Middle Eastern cold war’s southern flank to the Iron Curtain’s eastern anchor.

Russia’s shadow fleet (600+ tankers, per KSE Institute) now operates with Russian-flagged insurers (Rosgosstrakh, Ingosstrakh), Iranian crews, and UAE-transit financial clearance — a parallel maritime order connecting the Baltic Iron Curtain to the Gulf cold war through the Suez and Cape routes.

Turkey/NATO Politics

Turkey is NATO’s second-largest army and controls the Turkish Straits (Montreux Convention), giving it veto power over Black Sea access. Ankara blocked Swedish/Finnish NATO accession (2022-23), purchased Russian S-400 (triggering CAATSA sanctions and F-35 expulsion), and threatens Greek islands while hosting US nuclear weapons at Incirlik. Turkey’s defense industry (Baykar, TAI, Aselsan, Roketsan) now exports to 60+ countries including NATO allies (Poland TB2, Romania TB2, UK naval systems) while simultaneously developing indigenous TF-X fighter and ballistic missiles (Tayfun, Cenk) that reduce US dependency. NATO’s Article 5 commitment to Turkey constrains any anti-Turkish alignment; the alliance’s southern flank strategy still treats Ankara as the indispensable Black Sea gatekeeper regardless of Erdogan’s oscillations.

The Caucasus: Where the Curtain Meets the Cold War

Georgia’s 2024 “foreign agents” law and EU candidacy freeze reflect Russian pressure on the Caucasus southern flank. Azerbaijan leverages its energy corridor (TANAP/TAP) and Turkish alliance (Shusha declaration 2021) to balance Russia-Iran-Armenia, while Armenia’s CSTO membership and Pashinyan’s EU pivot create a three-way trap. Azerbaijan’s 2023 lightning offensive in Nagorno-Karabakh used Turkish Bayraktar TB2, Israeli Harop/Loitering munitions, and Pakistani JF-17 (reported) — a three-axis weapons demo that showcased the Turkey-Israel-Pakistan defense supply chain in combat.

The Chokepoint Calculus

The India-Middle East-Europe Economic Corridor creates an economic architecture that bypasses Iranian chokepoints. The Russian shadow fleet creates a parallel maritime order with its own flags and insurers. Iran gates access at Hormuz through the Persian Gulf Strait Authority.

Three systems competing for the same water. Maritime access has become the strategic currency.

This connects to the core logic of sea power. Geographic access to the global commons (the shared ocean and shipping lanes that cross it) is the primary determinant of great power longevity. Command of the sea must be re-earned continuously. Economic elasticity (the capacity to finance military operations long after initial mobilization peaks) not territory lets a coalition out-endure a land empire.

Why This Is Not the Old Cold War

The opposing case deserves its weight.

The Iran-centric frame remains the dominant structural driver: all regional alignments including Turkey-Saudi, Israel-UAE, and Pakistan balancing are derivative responses to Iranian expansion — nuclear threshold, proxy network, maritime coercion at Hormuz and Bab el-Mandeb. The new cold war is a reaction, not an independent dynamic.

Turkey-Saudi relations remain transactional. Saudi Arabia maintains deep defense ties with the United States including F-15, THAAD, and Patriot systems. Saudi Arabia has not substituted Turkish systems for American ones. The Bayraktar talks have not produced a signed procurement contract as of 2025.

Pakistan balances between China (J-10C fighters, CPEC, Gwadar port) and the United States (F-16 sustainment, IMF bailouts, counterterrorism cooperation), making it a swing state not a committed bloc member. Its Turkey ties are bilateral not multilateral.

Israel-UAE cooperation is narrow security coordination — air defense and maritime domain awareness. UAE maintains diplomatic relations with Iran, hosts Iranian trade, and has not joined Israeli strikes on Iranian targets.

Sunni-Shia proxy competition still explains more variance: Turkey’s neo-Ottoman outreach, Saudi’s custodianship of holy sites, Iran’s revolutionary export, and Pakistan’s sectarian management are all mediated through the sectarian cleavage, not a new great-power alignment.

Turkey and Israel normalized relations in 2022 (Herzog visit, ambassador exchange, energy talks on East Med gas); Turkish drones have been offered to Israel’s rivals but Turkey-Israel trade volume exceeds 10 billion dollars annually. This contradicts a clean bloc opposition.

NATO’s Article 5 commitment to Turkey constrains any anti-Turkish alignment; the alliance’s southern flank strategy still treats Ankara as the indispensable Black Sea gatekeeper.

The new Iron Curtain analogy overstates Russian capacity: Belarus is a vassal but Georgia’s EU candidacy (2023) and Armenia’s CSTO freeze (2024) show Russian influence receding, not solidifying, in the Caucasus.

Iran’s 300+ drone/missile attack on Israel in April 2024 (Operation True Promise) transited Iraqi and Jordanian airspace with tacit US coordination; the intercept involved US, UK, French, Jordanian, and Israeli assets — a live test of the Israel-UAE-US air defense architecture that Iran probed for gaps.

Egypt sits uneasily between the axes: Sisi’s regime receives UAE-Saudi financial lifelines (20+ billion since 2013) and Israeli intelligence coordination in Sinai (Operation Martyr’s Right), but Cairo views Turkish-backed Muslim Brotherhood networks as an existential threat and opposes UAE-backed Haftar in Libya while Turkey backs the GNA.

What Endurance Looks Like Now

The coalitions that protect maritime access outlast. The new cold war is fought at the gates, not the capitals.

Specific evidence of a Saudi-Turkish joint production facility groundbreaking or signed TB2-Akinci procurement contract has not been publicly confirmed. Pakistan TF-X Kaan program participation beyond media reports awaits official statement from Turkish Aerospace Industries or Pakistan Aeronautical Complex. IMEC corridor implementation milestones post-October 7 2023 await US State Department or Saudi MISA official progress reports. UAE SAF/STC/Somaliland funding amounts and channels await UN Panel of Experts reports or UAE Federal Audit Authority disclosures. Israeli-Somaliland intelligence sharing specifics await Mossad archives (unlikely) or Somaliland Ministry of Foreign Affairs statements.

The absences are as telling as the presences. The defense-industrial spine is being built. The economic architecture is being laid. The maritime front is active. The contracts that would make the coalitions irreversible remain unsigned.

That is where the region stands. Two blocs forming across the water. The Iron Curtain descending from the north. The old frames do not fit. The new one is still hardening. Watch the chokepoints. Watch the contracts. Watch the water.
