Daily Summary of Global Maritime Geopolitics

The global geopolitical landscape between June 19 and 21, 2026, is dominated by three converging axes of tension: fragile US-Iran diplomacy and its impact on maritime energy routes; the persistent erosion of the Russian-Ukrainian conflict with new actors and asymmetric technologies; and the redefinition of transatlantic relations under pressure from the Trump administration. These three interconnected dynamics cannot be interpreted in isolation.

Key events

The Fragile US-Iran Memorandum and the Reopening of Hormuz On June 18, 2026, a Memorandum of Understanding was signed between Washington and Tehran, formally suspending hostilities, lifting the US naval blockade of Kharg Island, and partially restoring transit through the Strait of Hormuz. Qatar resumed LNG exports at 80% capacity, but damage to two liquefaction plants has structurally reduced supply by 12.8 million tons/year. RUSI warns that the agreement does not address the root causes of the conflict and risks creating a “permanent crisis” ( RUSI ).

NATO’s Strategic Review and the Transatlantic “Double Tear.” Defense Secretary Pete Hegseth announced in Brussels a six-month review of the U.S. military presence in Europe, dubbed “NATO 3.0,” with the goal of reducing America’s conventional commitment and transferring responsibility for air and ground defense to allies. Meanwhile, Trump’s harsh remarks toward Italian Prime Minister Meloni at the G7 summit in Evian—which Palazzo Chigi called “totally fabricated”—have exacerbated what ISPI describes as a “double tear” that undermines the Alliance’s trust (Reuters, ISPI ).

The STEP Agreement and the New Sunni Architecture The Cairo Summit of June 21 sanctioned the transformation of the quadrilateral STEP consultative mechanism—Saudi Arabia, Turkey, Egypt, and Pakistan—into a permanent institutional platform. The agreement, rooted in the Saudi-Pakistan Pact of September 2025 and the Riyadh Summit of March 2026, outlines a new “Sunni NATO” based on three pillars: strategic autonomy from the US, containment of Iran, and economic and military integration among the four countries (IARI, June 21, 2026).

Peruvian Presidency Keiko Fujimori is close to becoming Peru’s president, narrowly beating left-wing rival Roberto Sánchez with 99% of the votes counted. In her fourth attempt, Fujimori inherits a country marked by a decade of political instability and fragmentation, partly fueled by her obstructionist post-2016 strategy. Despite endemic corruption and rising crime, the Peruvian economy demonstrates resilience thanks to copper and gold exports, with Goldman Sachs forecasting the highest growth in Latin America for 2026.

The environmental emergency posed by plastic The global plastic crisis is emerging as a devastating environmental, geopolitical, and public health emergency, with industrial production far exceeding disposal capacity. A  Foreign Affairsanalysis  highlights that uncontrolled proliferation, including that of microplastics, threatens the biosphere as much as climate change, triggering international disputes. A binding global treaty is being called to limit the production of virgin polymers and encourage a circular economy.

The Geopolitical Costs of the US-Iran War A study by the  Council on Foreign Relations  analyzes the Trump administration’s “maximum pressure” strategy against Iran, highlighting its ineffectiveness in achieving its stated objectives. Withdrawal from the JCPOA ( Joint Comprehensive Plan of Action  , also known as the Iran nuclear deal) and sanctions have failed to limit Iranian influence, instead pushing Tehran to accelerate uranium enrichment and intensify regional hostilities. The aggressive policy has also eroded diplomacy, increased risks for US troops, and fueled instability in energy markets.

The Forgotten Human Cost: A study by  Responsible Statecraft  highlights how the US-led post-9/11 conflicts have generated a humanitarian catastrophe, producing millions of refugees and displaced persons in Iraq, Afghanistan, Libya, Syria, and Yemen. The analysis denounces the impact of “endless wars” on civilians and geopolitical destabilization, urging Washington to prioritize diplomacy and aid over interventionism.

Why Russia Hasn’t Settled Its Account with Armenia Yet An analysis by  The National Interest  highlights tensions between Russia and Armenia in the South Caucasus, where Moscow maintains strong leverage despite Yerevan’s rapprochement with the West. Controlling energy and military infrastructure, the Kremlin is using territorial disputes with Azerbaijan to slow down Armenia’s geopolitical transition and defend its regional hegemony.

Consequences of the events that occurred

Geopolitical consequences

This week accelerates the transition to a multipolar order, characterized by a growing fragmentation of strategic loyalties. The emergence of the STEP axis introduces a fourth regional power pole into the international system, alongside—sometimes in opposition to—the Western, Russian-Chinese, and Indian blocs. The emergence of this institutionalized Sunni architecture profoundly alters deterrence calculations in the Middle East, reducing the room for maneuver for both Washington and Tehran. The partial US disengagement from Europe, formalized by Hegseth’s “NATO 3.0” revision, creates a security vacuum that European capitals are struggling to address, both financially and industrially. Poland, revoking Zelensky’s Order of the White Eagle over trade disputes, signals the first cracks in the Eastern bloc of Ukraine’s staunchest allies. Kiev’s ultimatum to Minsk regarding the drone relay network adds another potential escalation front in the Northern European theater. Globally, China is consolidating its economic penetration in Latin America by countering Trump’s tariff pressure; Russia has decided to orient its foreign and economic policy toward Southeast Asia to circumvent Western isolation; India maintains a strategic anchor with Washington while maintaining parallel channels with Moscow. Colombia, in the presidential runoff, becomes a new testing ground for the contest between progressivism and right-wing nationalism in the Western Hemisphere.

Strategic consequences

On the military front, the week is marked by three significant signals for Western defense. The first is the Royal Navy’s warning to NATO leaders: Allied navies remain too anchored to obsolete doctrines and are unprepared to absorb the lessons of the Black Sea, where sea-based drones, land-based anti-ship missiles, and real-time satellite intelligence have demonstrated the vulnerability of large conventional surface vessels ( Navy Lookout ). The second is the operational debut of the Ukrainian Triton drone, a surface platform with almost no radar signature and a long range, forcing the Russian Black Sea Fleet to spend heavily on defense in its home ports. The third is the deterioration of interceptor missile stockpiles in US arsenals: the US is unable to produce enough missiles to face parallel crises in Europe, the Middle East, and the Indo-Pacific, due to shortages in the supply chain of critical materials and bureaucratically rigid acquisition processes ( The National Interest ). In parallel, at Eurosatory 2026, MBDA presented the NCM-LCM MK2, a sea-to-land cruise missile mobilizable in less than 15 minutes, and signed an MoU with LUCH for the Ukrainian Neptune 2. The Italian-French SAMP/T NG advanced as a European alternative to the Patriot. Japan’s Terra Drone acquired two Ukrainian startups specializing in interceptor drones, signaling the global industrialization of Ukraine’s warfare expertise.

Economic, technological, financial and energy consequences

The partial reopening of Hormuz has brought oil prices back to levels below their crisis peaks, but Qatar’s 80% LNG export capacity does not equate to normalization: the 17% structural deficit creates a persistent spread and a risk premium that penalizes long-term contracts in particular. Importing companies and governments are being called upon to incorporate industrial insurance clauses and diversify their sources, because the vulnerability of  maritime chokepoints has become structural, not episodic ( IARI, ISPI ). On the technological front, China has achieved supremacy in neuroscience and brain-computer interfaces, opening up military applications that  InsideOver  calls a “new Sputnik moment” for Washington. Beijing is also planning a mega-constellation of 200,000 satellites to compete with Starlink in the aerospace domain. The critical link between AI expansion and water consumption is emerging urgently: data centers training advanced language models require millions of liters of water daily, turning water scarcity into a geopolitical bottleneck in the global technology race. Major Japanese corporations, which invested $500 billion in the US to circumvent Trump’s tariffs, are seeing lower-than-expected returns due to high labor costs and persistent inflation. Cuba, under embargo, is timidly opening up to the private market. Algeria and Morocco—despite their bilateral rivalries—are emerging as complementary hubs for gas supplies to Europe.

Maritime consequences

The maritime theater is the beating heart of the geopolitical week analyzed. The Strait of Hormuz, through which over 20% of the world’s oil needs pass, remains the epicenter of the crisis: the resumption of loading operations from Kharg Island is confirmed by satellite images of waiting supertankers, but the threat of Iranian naval mines—an arsenal of thousands of acoustic, magnetic, and pressure-sensitive devices—keeps insurance premiums high and Western mine-clearing capabilities structurally inadequate (The Hill). CENTCOM has intensified surveillance operations with destroyers, P-8 Poseidons, and long-range drones. The  Jewish Policy Center article  and the Royal Navy’s analyses converge on a crucial point: asymmetric maritime warfare has redefined the very concept of sea control. Ukrainian surface-based unmanned vehicles (USVs)—particularly the Triton—prove that a navy without a fleet can deny the sea to a conventional fleet. Turkey is monetizing the Bosphorus and Dardanelles Straits by exploiting the Montreux Convention, imposing new transit tariffs that affect Russia, Ukraine, and the Danubian countries, and strengthening Erdoğan’s geopolitical leverage. In the Black Sea, a Panamanian merchant vessel was struck by a kamikaze drone, killing one and injuring two: the incident confirms that civilian trade routes remain exposed to asymmetric operations without clear attribution. In the Eastern Mediterranean, disputes over EEZs between Egypt, Cyprus, Israel, and Turkey over offshore oil fields are intensifying, with NAVTEX and offshore shipyards becoming vectors of operational and military friction. Illegal industrial fishing (IUU) in West Africa—denounced by  IARI  —completes the picture of an ocean governance crisis fueling social instability and forced migration.

Consequences for the Mediterranean European nations

For the three main players in the Southern Mediterranean, the week offers both challenges and major strategic opportunities. Italy is at the center of a complex diplomatic puzzle. The Trump-Meloni controversy at the G7—with the US president’s dismissive remarks labeled “invented” by Palazzo Chigi—is not a protocol incident but a test of bilateral relations at a time when Washington is asking Rome to deploy its minesweepers in the Strait of Hormuz. Edward Luttwak, on  Formiche.net , interprets this request not as subordination but as an opportunity: participating in the security of Hormuz would mean for Italy protecting its energy supplies and gaining real political credibility with the White House, demonstrating its status as a “key partner in the broader Mediterranean.” On the industrial front, the appointment of Admiral Credendino as president of Orizzonte Sistemi Navali (Fincantieri 51%, Leonardo 49%) reflects the porosity between military leadership and the defense industry, a dynamic that Stampalibera.it describes as similar to the American and Israeli revolving doors. At the same time, Italy is holding back military aid to Kiev to preserve its arsenals, confirming a posture of national strategic caution. Greece is increasingly monitoring the evolution of the Eastern Mediterranean: the geographic compression of the EEZs between Athens, Ankara, Cyprus, and the Levant is amplifying legal and operational tensions over offshore fields. The STEP agreement with Egypt as a regional gas hub puts Athens in an awkward position, while Erdoğan’s monetization of the Straits is impacting Black Sea trade flows passing near Greek waters. ELISME, a CESMAR partner, will operate in a highly dense strategic area where maritime supervision of offshore construction sites is a matter of national security rather than foreign policy. Spain, currently engaged in the operational testing of the Hornet Block 1 fixed-wing interceptor drone from the frigate Santa María, is advancing its naval air defense modernization program, strengthening its autonomous capabilities to respond to attack drones and low-altitude cruise missiles in the Mediterranean and Atlantic. Spain’s interest in the SAMP/T NG system and the MBDA consortium is part of a broader European “strategic shield” project aimed at reducing dependence on the US Patriot missile. The elections in Colombia—with a far-right candidate leading the way—are of interest to Madrid because of its Latin American community and its strategic investments in Latin America, an increasingly contested region between Washington and Beijing.

Conclusions

The week of June 19-21, 2026, does not deliver solutions, but rather new crisis architectures. The US-Iran memorandum is a tactical truce, not a structural peace:  RUSI  and  Foreign Affairs  agree that the stalemate is inherently unstable and vulnerable to any incident in Lebanon or the Straits. The STEP axis marks the institutionalization of an alternative power pole that will alter regional deterrence calculations for the coming decade. The American disengagement from Europe, albeit partial, requires southern NATO countries to accelerate their defense industrial autonomy. Developments are expected in the coming days regarding: the outcome of the Colombian presidential runoff (impact on Latin American balances of power); possible new Israeli raids in Lebanon (which could trigger the Hormuz closure clause included in the Iranian ultimatum); the progress of the two-phase Ukrainian ceasefire negotiations circulating in European governments; and Minsk’s response to Zelensky’s ultimatum on drone relays. For Italy, the immediate test remains the decision to send minesweepers to Hormuz: a choice that will define Rome’s true weight in the new Atlantic geometry.
