Abstract

“Old Theatres – New Challenges,” captures with precision the transformation we are witnessing across the maritime domain. Historic basins of maritime activity—from the Atlantic and Indian Oceans to the Greater Mediterranean—are confronted with new covers of complexity: technological acceleration, evolving security norms, pressure on critical infrastructure, and the rise of non-traditional threats that shape the boundaries between peace, competition, and conflict...

Since middle 2025, Lebanon has seen a significant shift in its approach to non-state armed groups, particularly Hezbollah. The government, under Prime Minister Nawaf Salam, has tasked the Lebanese Army with a plan titled “Homeland Shield” to centralize all weapons under state control. This initiative marks one of the most substantial challenges to Hezbollah’s military autonomy in decades (Al Jazeera, 2025).

The Government’s “Homeland Shield” Plan

In August 2025, the Lebanese cabinet empowered the Army to develop a strategy to monopolize all arms under state institutions by the end of the year (Al Jazeera, 2025). This decision responds to domestic and international pressures to disarm militias, chiefly Hezbollah, and restore the Lebanese state’s sovereignty (Ministry of Information, Lebanon, 2025). ..

On 11 November 2025, Reuters wrote that the Ursula von der Leyen, President of the European Union Commission pointed out the creation of an Intelligence body which will hire officials from across the European Union member states as well as improve the use of information gathered by national intelligence services.

The author of the editorial published an article in 2005 focused on the creation of a European Union Intelligence Service (EUIS) and it was published in the International Journal of Intelligence and Counterintelligence (IJIC) in USA.

Even though it took the European Union twenty years to consider the creation of a European Union Intelligence Service (EUIS), I believe it is on the right direction. In the future, the next step for the European Union should be to transform the European Security and Defense College (ESDC) into a European Union Intelligence University that will provide train and educate European officers in the forthcoming European Army as declared by European Union officials. Reduced duplication and closed cooperation among the EU member-states offers an opportunity for efficient intelligence cooperation.

The emerging intelligence service in the European Union should have as its most important task the analysis of overtly as well as covertly gathered information and preparing it for use by policy-makers. One of its goals is to bring together experts from both the intelligence and security services.

A concept of synergy between public and private sectors that is quite difficult to be proven in Greece, the European Commission must form a strong collaboration between private and public sectors that focus on analytical and intelligence branches as well as on enhancing non-for-profit research think tanks upon open-source intelligence analyses which would allow the European Union Intelligence Service (EUIS) to advice the European Commission and the European Council on foreign and security issues for prospective conflicts in Europe.

The next decades in the 21st century, the Human Intelligence Networks (HUMINT) and the Artificial Intelligence (AI) will require an evolutionary approach on training and educating the generation of the future intelligence analysts and practitioners to the methods and systems that are needed to know in order to face the emerging non-state actors, hybrid warfare threats and the need for stronger defenses against psychological operations (cognitive security). As Brigadier General (ret’d) Ioannis Galatas correctly states: “The unexpected is the new normal.”

Introduction: The Energy Chessboard Beneath the Waves

The Eastern Mediterranean has always been a crossroads of empires, trade, and conflict. Today, it is also a crossroads of pipelines, floating terminals, and liquefied natural gas (LNG) carriers. The quiet realignment now underway in the region is not being shaped by military power or rhetoric, but by infrastructure and energy flows.... Read more

The recent initiative by the Greek Prime Minister to establish a multilateral cooperation scheme titled “5×5” marks an ambitious effort to reposition Greece at the core of Mediterranean developments. Although primarily a political and diplomatic proposal, it also holds significant potential within the framework of Maritime Spatial Planning (MSP) and multi-level ocean governance in the Mediterranean.....

As Israel, Greece, and Cyprus forge a new security triangle in the Eastern Mediterranean, Ankara’s long-standing occupation of Northern Cyprus has shifted from a historical anomaly to a live strategic liability. A phased Turkish withdrawal, monitored by international forces, could transform the island from a frozen conflict into the cornerstone of a rule-based order.... Read more
