Strengthening the Anglosphere: The AUKUS era and the new global geopolitical scenario

(To Giuseppe Gagliano)

In the current global context, characterized by intense geopolitical dynamism and challenges to international stability, the emergence of the AUKUS (Australia, United Kingdom, United States) represents a significant turning point in the fabric of military and technological alliances. This trilateral alliance not only signals a profound evolution of the Anglosphere but also lays the foundation for a new strategic order in the Indo-Pacific, with repercussions that extend far beyond this region.

Origins and purposes of the AUKUS

AUKUS originates from a long history of cooperation between English-speaking nations, sharing cultural, historical and value roots that date back to the British colonial era. However, the alliance does more than celebrate historic ties; rather, it is a calibrated response to the challenges posed by the rise of China and Russia's renewed assertiveness on the international level.

With China expanding its influence in the Pacific and Russia showing increasing hostility in Europe and elsewhere, AUKUS aims to strengthen military deterrence and promote a "free and open" Indo-Pacific, according to democratic principles and rule of law.

At the heart of AUKUS is the transfer of advanced technologies, particularly in the area of ​​submarine defense and nuclear capabilities, which marks a point of no return for Australia. The latter, traditionally cautious in adopting nuclear energy, agrees to host nuclear-powered submarines, highlighting a qualitative leap in its national security doctrine. This movement strengthens not only Australia's deterrence capabilities but also its integration into the collective security strategies of the Anglosphere.

A new dynamic in the Indo-Pacific

The Indo-Pacific emerges as the central theater of this new power dynamic. The AUKUS not only symbolizes intensifying strategic competition with China but also an attempt to establish a counterweight to Beijing's growing militarization and territorial ambitions.

The alliance also signals a commitment to a greater military and technological presence in a region crucial to global trade routes and maritime security

Despite its strong cooperative footprint, AUKUS raises questions about the sovereignty and decision-making autonomy of its members, particularly regarding the risk of Australia's military and technological dependence on the United Kingdom and United States. However, the alliance also emphasizes a model of international collaboration that goes beyond the mere sharing of military capabilities, promoting a broader exchange of advanced technologies, research and development in critical areas such as artificial intelligence, cyber warfare and underwater surveillance .

Towards an uncertain future

While the AUKUS embodies a bold strategic vision and an aspiration for a stable and democratic Indo-Pacific, it also places the Anglosphere at a historical crossroads. Its success will depend not only on the ability to navigate the complexities of international relations but also on the ability to maintain a balance between the reaffirmation of historical ties and the need to respond to emerging challenges in a multipolar world. Ultimately, the AUKUS it is not only a testimony to the strengthening of the Anglosphere but also a harbinger of the future of global geopolitics.

The alliance signals a movement towards more agile and focused security formations, capable of quickly adapting to a changing international environment. AUKUS's ability to serve as an effective deterrent and foster a shared vision for the Indo-Pacific will be crucial to its long-term impact on regional and global security.

A key element to monitor will be the effect of the AUKUS on international power dynamics, including the reaction of other regional and global powers. India and ASEAN countries, for example, play critical roles in the Indo-Pacific, and their response to the alliance could range from a cautious collaborative approach to concerns about increased military tensions. Furthermore, the reaction of China, which has already expressed strong opposition to AUKUS, will further define the contours of the new regional balance of power.

Strategic issues 

The nuclear component of the AUKUS raises significant ethical and strategic questions. While it offers Australia an unprecedented boost to its military deterrence, it raises questions about the prolongation of the arms race and nuclear proliferation. Transparent and accountable management of these capabilities will be key to maintaining international trust and ensuring that the alliance effectively contributes to global stability without triggering new spirals of tension.

The AUKUS could also serve as a catalyst for a more collaborative security architecture in the Indo-Pacific, which includes strengthening other regional partnerships such as the Quad (Quadrilateral Security Dialogue between Australia, India, Japan and the United States). The synergy between these alliances could provide a comprehensive response to security challenges, while promoting an international order based on shared rules and mutual respect.


The era of AUKUS is more than just a defense agreement; it is a sign of changing geopolitical paradigms and the search for new forms of international collaboration in response to the emerging challenges of the 21st century. As the world adapts to this new reality, the effectiveness, accountability and integration of the AUKUS into the broader fabric of international relations will define its role in shaping the future of global geopolitics.

In this context, the Anglosphere not only strengthens its internal ties but also positions itself as a central actor in dealing with the complexities of an interconnected world.
