The Strait of Gibraltar ranks among the world’s most vital maritime chokepoints. Approximately 100,000 vessels transit it each year, handling more than 10 percent of global maritime trade, 6 million passengers, and 60 million 20-foot equivalent units of container cargo. At its narrowest point of 8.6 miles, the strait compresses the western Mediterranean into a single artery. Any power dominating the southern shore commands leverage over European supply routes and North Atlantic Treaty Organization logistics. Geography alone turns this passage into a prize.
The parallel to Gibraltar sharpens the point. Spain aggressively pursues the return of the British enclave at the strait’s eastern gate, invoking anti-colonial rhetoric and United Nations resolutions. Yet it refuses to apply identical logic to its own holdings just across the water. This inconsistency is not lost on Rabat or Jerusalem.

Iran routinely disrupts the Strait of Hormuz with naval mines, an illegal toll system, and threats to oil tankers. Morocco and Israel have chosen the opposite path. Their partnership in the Strait of Gibraltar rests on mutual consent, advanced technology, and joint maritime awareness. It operates within the United Nations Convention on the Law of the Sea and delivers measurable strategic advantage without violating international law.
Spain occupies two enclaves, Ceuta and Melilla, on Moroccan soil. These territories cover just over 11 square miles and house approximately 170,000 residents, mostly Spanish citizens. Melilla fell to Spanish forces in 1497 amid the “Reconquista.” Ceuta, originally Portuguese, transferred to Madrid in 1580 following the Iberian Union. When Morocco gained independence in 1956, Spain retained both enclaves as national territory. Ironically, the United Nations has declined to place them on its list of non-self-governing territories slated for decolonization, accepting Madrid’s argument that they form part of metropolitan Spain.
Morocco begs to differ. That unresolved dispute has only deepened as Madrid moves to further entrench its presence in the enclaves through major economic and infrastructure investments. Spain has invested $828 million in the enclaves between 2023 and 2026. Yet Madrid routinely denounces colonialism elsewhere and insists on strict adherence to international law while shielding its own North African holdings from the same criteria.
This double standard has grown untenable. The enclaves survive only through sea lines of communication now under expanding Moroccan-Israeli technological surveillance. No ground assault or naval blockade is required. Persistent monitoring, integrated air and missile defenses, and calibrated domain denial reshape the operational landscape through geography and superior systems.
The Polisario Front, backed by Algiers, received Iranian Islamic Revolutionary Guard Corps drones and Hezbollah training in urban warfare and technical operations.
Jerusalem and Rabat’s defense partnership supplies concrete capabilities. Earlier this year, the two countries signed their latest joint military work plan in Tel Aviv. Morocco fields Israeli Heron drones for nonstop coverage and has deployed Barak MX systems worth roughly $500 million, ELTA radars, ATMOS artillery, and locally produced SpyX munitions.
This cooperation also counters the growing Algeria-Polisario-Hezbollah axis. The Polisario Front, backed by Algiers, received Iranian Islamic Revolutionary Guard Corps drones and Hezbollah training in urban warfare and technical operations. American lawmakers introduced legislation in March 2026 to designate Polisario a Foreign Terrorist Organization precisely because of these ties and its role in moving weapons on Iran’s behalf.
A joint maritime domain awareness center on Morocco’s northern coast fuses Israeli drones, radars, electronic warfare, and command networks with Moroccan sovereignty, delivering permanent oversight over shipping lanes serving the Spanish enclaves. Spain’s exclusion from the United States-led Flintlock 2026 exercises in Libya, where Morocco participated, underscores Madrid’s eroding regional posture amid deepening Rabat-Jerusalem-Washington ties.
These shifts carry implications for U.S. interests. Strengthened Moroccan capabilities, integrated with Israeli technology, enhance oversight of a critical chokepoint for European energy supplies and North Atlantic Treaty Organization logistics, while helping to constrain Iranian proxy networks in North Africa.
As the Abraham Accords mature into military and intelligence partnerships between Israel and the moderate Sunni Arab states, the foundations of an emerging “Abrahamic NATO” are beginning to take shape. For Washington, this evolving multi-domain security axis offers a strategic opportunity to reinforce its southern European flank and strengthen counter-proliferation efforts across the Mediterranean basin.
Madrid condemns violations of international law while arming a regime hostile to the Jerusalem-Rabat alliance and clinging to its own colonial enclaves.
These developments alter the balance of power in real time. Spanish resupply ships to Ceuta and Melilla must sail through waters where Moroccan-Israeli interoperability sets the terms. Heron drones provide intelligence. Layers of SpyX loitering munitions, Barak MX interceptors, and electronic warfare suites create the latent capacity for swarm-level disruption that raises insurance premiums, delays schedules, and imposes direct economic costs.
Madrid’s contradictions deepen the pressure. Spain imposed a total arms embargo on Israel in October 2025, yet approved $1.5 million in dual-use exports to Iran from 2024 to mid-2025 and nearly $199 million in defense transfers in 2024. Madrid condemns violations of international law while arming a regime hostile to the Jerusalem-Rabat alliance and clinging to its own colonial enclaves.
Spain’s 2022 decision to back Morocco’s autonomy proposal for Western Sahara revealed a capacity for realpolitik when interests and blackmail align. The same pragmatism is absent from its Israel policy and its insistence on preserving 15th-century conquests.
While Morocco secures European energy routes, protects maritime commerce, and intensifies its campaign against narcotics networks, Spain remains trapped in moralizing politics and watching its southern flank grow more vulnerable. Madrid is even dismantling military units once central to combating drug cartels, weakening itself at the precise moment regional competition is hardening. The strategic message is impossible to ignore: Adapt to the emerging balance of power or watch influence, leverage, and credibility slip away through the very strait Spain once commanded.
