Between Scylla and Charybdis: The Geopolitical Labyrinth of the South Caucasus

Listen to the AI generated audio article. 

The South Caucasus has long been a place where major powers collide, a narrow corridor where empires, and now modern states, compete for influence. For Armenia, a small landlocked country with few natural resources, that geopolitical reality has always felt existential. 

Russia’s invasion of Ukraine in 2022, followed by the loss of Nagorno-Karabakh in 2023, fundamentally altered Armenia’s strategic environment. Together, these events exposed the collapse of the post-Soviet security architecture and forced a radical reevaluation of Armenia’s place in the region. 

In response, Yerevan executed a bold maneuver: shifting away from decades of reliance on a single security guarantor toward a model of strategic diversification.

This article examines Armenia’s geopolitical evolution through the lenses of small state theory and Three Seas System theory. The argument is straightforward: Armenia’s current foreign policy is not simply a reactive shift toward the West, but a sophisticated attempt to redefine the country as a critical node within a unified mega-region spanning the Mediterranean,  Black and Caspian seas. By analyzing the influence of Russia, the European Union, and the United States, this study traces how Armenia navigates a fragmenting world order while trying to leverage its location for long-term survival and prosperity. 

Understanding Armenia’s foreign policy today requires beginning on theoretical terrain. Small states are defined, in large part, by their limited capacity to shape the international system, and by their disproportionate vulnerability to external shocks. It’s a simple but powerful lens. According to small state theory, such nations often seek military, economic, or political alliances with larger powers or multilateral organizations as a way to mitigate these inherent vulnerabilities.

Historically, Armenia directed that search for security alliances almost exclusively toward Russia. Bandwagoning was seen as the only viable response to existential threats: closed borders with Turkey and Azerbaijan, and an unresolved conflict. The vulnerabilities of the Russian-led security architecture became glaringly evident during the 2020 Artsakh War and its immediate aftermath, revealing that the Collective Security Treaty Organization’s protections were largely illusory. Russia’s subsequent full-scale invasion of Ukraine in 2022 compounded this shift, further diverting Moscow’s resources and reinforcing its regional deprioritization. In response, Armenia has abandoned its reliance on a single security patron in favor of a deliberate policy of multi-alignment. By actively building diverse strategic partnerships, Yerevan is attempting to construct a more resilient foundation that more durably spreads its security and economic risks.

Complementing this is the Three Seas System theory, developed by Professor David Hovhannisyan. The framework proposes that the Mediterranean, Black and Caspian seas, together with the landmasses between them, form a unified mega-region with shared infrastructural, economic and strategic dynamics. From this perspective, the South Caucasus is not a peripheral frozen zone; it is a vital link in the global network of communication and transportation. 

Three Seas System theory argues that power today flows less from controlling territory than from controlling networks. For Armenia, this is more than an abstract idea, it offers a practical roadmap. The challenge is to turn its landlocked geography from a liability into a strategic asset. By becoming a transit hub for both north-south and east-west corridors, particularly through initiatives such as the Crossroads of Peace, Armenia hopes to embed itself so deeply in regional infrastructure that its security and stability become a shared interest across the wider mega-region: not as charity, but as a shared interest. 

Armenia’s Strategic Significance in the South Caucasus

Armenia’s geography is an accident of history; a hinge between Europe and Asia. That position is both a source of vulnerability and a rare advantage. The country sits at the intersection of the Christian West, the Islamic South, and the post-Soviet North — regions whose interests sometimes converge, but often collide. 

Then came 2023. The loss of Nagorno-Karabakh carried an immense human and national cost. Yet, viewed strictly in strategic terms, it also reshaped Armenia’s calculations. A longstanding obstacle to deeper regional integration had disappeared. What remained was a clearer strategic landscape, and fewer excuses for delaying difficult choices.

From the Three Seas System perspective, Armenia’s security is inseparable from the stability of the Black Sea basin. The annexation of Crimea and the subsequent full-scale invasion of Ukraine have turned the Black Sea into a zone of intense NATO-Russia confrontation. As a small state within this system, Armenia is directly impacted by the “chaos” that Hovhannisyan describes as a feature of competition between global infrastructure projects. Whether it is the Chinese Belt and Road Initiative, the Western-backed Middle Corridor, or the Russian-Iranian North-South Transport Corridor, Armenia’s territory remains a potential “missing link” that all parties seek to influence.

The signing of the Washington Accords on August 8, 2025, and the introduction of the Trump Route for International Peace and Prosperity (TRIPP) mark a new phase in this competition. Far from serving as a mere regional bridge between Azerbaijan and Turkey, TRIPP is positioned as a critical node in the Trans-Caspian Middle Corridor. Its strategic utility lies in its ability to link European markets to Central Asia through Armenian territory. If everything holds, the Three Seas potential could finally be unlocked: a continuous transport corridor running from the Caspian all the way to the Mediterranean. That is the vision, at least.

For Armenia, the question is where the real weight of these projects will fall. Will they respect the country’s sovereignty and deliver tangible economic benefits? Or will they become instruments of larger powers, designed to bypass one another while leaving Yerevan little more than a transit route? The answer is not yet written, but the stakes could hardly be higher.

The Influence of Major Powers: Russia, the United States and the EU

To understand why allegiances are shifting across the South Caucasus, you have to start by looking at Armenia’s relationships with the major global powers. The steady decline of Russian influence, the assertive push from the United States, and the expanding normative reach of the European Union are unfolding simultaneously. Together, these competing geopolitical vectors exert a triad of pressures on Yerevan, forcing Armenian foreign policy to navigate a highly volatile environment with zero margin for error. 

The Russian Federation: From Guarantor to Competitor
For three decades, Russia was the foundation of Armenian security. The 102nd Military Base in Gyumri and Armenia’s membership in the CSTO were understood as the ultimate deterrents—positioning Moscow as the primary counterweight to the existential security threat posed by Turkey and Azerbaijan. 

Then came the Russian-Ukraine war, which fundamentally shifted Moscow’s strategic priorities. To sustain its war effort and circumvent Western sanctions, Russia began prioritizing its relationships with Turkey and Azerbaijan, both key transit and energy partners. From Yerevan’s perspective, the result looks like a strategic abandonment.

The signs were not subtle. Russia failed to intervene during the 2021 border incursions. When the Nagorno-Karabakh Republic dissolved in 2023, Moscow stood aside. This marked the end of what had been a security alliance. 

Armenia responded by beginning a de-facto withdrawal from the CSTO: freezing its participation and looking elsewhere for military suppliers. France and India have stepped in. But the transition carries real risk. Russia still holds considerable economic leverage over Armenia, including control over energy infrastructure and railway systems. 

The Three Seas System theory offers a way to interpret Moscow’s reaction. It suggests that Russia views Armenia’s reorientation as more than a straightforward political betrayal: it is a threat to Russian control over the vital communication lines that connect the Caspian and Black seas, a loss Moscow is unlikely to accept quietly.

The United States and the TRIPP Initiative
The U.S. has shifted into a mediating role in the South Caucasus, largely occupying the space Russia vacated as it became consumed by Ukraine. The Washington Peace Summit in August 2025 marked a turning point: President Donald Trump hosted the leaders of Armenia and Azerbaijan, and the parties signed a comprehensive normalization framework. Central to this American approach is TRIPP. It is more than a transportation project, though it is that as well. 

Think of it as a geopolitical instrument, designed to draw the South Caucasus into the Western economic orbit. The logic is straightforward: by opening trade between Azerbaijan, Armenia and Turkey, the United States aims to build a stable, pro-Western corridor that bypasses Russia to the north and Iran to the south. For Armenia, TRIPP cuts both ways. On one hand, it offers a path out of economic isolation. On the other, it risks tying Yerevan’s economic infrastructure to a new network of strategic partners whose long-term commitment to the region may shift with the tides of domestic politics. None of this comes without cost. Still, the direction is clear: America is no longer a distant observer in the South Caucasus; it is becoming an active architect of regional connectivity.

The European Union: Normative Power and Institutional Integration
The European Union’s relationship with Armenia has undergone a quiet but significant transformation. What once amounted to development aid has evolved into something closer to a soft security role. The EU Mission in Armenia (EUMA) patrols the border with Azerbaijan as a civilian monitoring presence, offering a kind of normative shield that partially compensates for the hard military guarantees Armenia lacks. 

The Armenian parliament’s 2025 declaration of intent to apply for EU membership is more than a geopolitical calculation. The EU’s influence here rests on the logic of the Three Seas framework: connectivity and shared values. Through the Eastern Partnership and various investment programs, Brussels is working to bring Armenia’s regulatory and infrastructural standards into line with European norms. The aim is to make Armenia more attractive to global investors and more resilient against external pressure. 

But the road to integration is long, and the required reforms are painful. They threaten entrenched interests among domestic elites and unsettle regional neighbors. None of this comes without cost. Yet the direction is clear: Europe is not just a partner for Armenia; it is becoming a structural anchor.

The New World Order: Armenia’s Role in a Fragmented System

The Russia-Ukraine war has accelerated a trend that was already underway: the old “rules-based” international order is fraying, and competing regional blocs are rising in its place. Against that backdrop, the Three Seas System can be seen as a smaller mirror of the broader struggle over who controls connectivity. Armenia, meanwhile, finds itself as a “pivotal small state”—not powerful on its own, but capable of influencing larger geopolitical projects if it plays its cards well. 

The core claim of the Three Seas System theory is that, in a networked world, the state must adapt in order to endure. Armenia is pursuing this kind of adaptation through its Crossroads of Peace initiative, which calls for reopening all regional communications on the basis of sovereignty, jurisdiction and reciprocity. In doing so, Yerevan hopes to avoid being reduced to mere “transit territory” for others and instead become an active shaper of the regional economy.

General Opportunities and Challenges in Balancing Multiple Partners

Armenia’s turn toward strategic diversification, sometimes described as a “pivot” or “tilt”, offers real promise but also serious difficulty. The key opportunity is greater sovereignty. By reducing reliance on a single patron, Yerevan gains more room to negotiate favorable terms across its international engagements. The Three Seas System provides the geographic and economic rationale for this reorientation, enabling Armenia to frame its security not as a narrow local predicament but as a matter of regional significance.

Opportunities

Economic Diversification and Growth
Diversifying trade routes and attracting investment from the EU and the United States offers Armenia a clear path to reduce its long-standing economic reliance on Russia. Along the way, entirely new growth sectors could emerge. The TRIPP initiative, for all its political entanglements, provides a concrete mechanism for linking Armenia into wider Eurasian trade networks. The shift in status could be transformative: from a landlocked state to a land-linked hub. 

Strengthened Security Partnerships
On the security front, this diversification brings immediate practical benefits by ending the former monopoly on Armenia’s defense procurement. France and India have emerged as key pillars, supplying advanced artillery, air defense systems, and tactical training. At the same time, cooperation with the United States has deepened, marked by the acquisition of American military technology and a critical Memorandum of Understanding aimed at developing Armenia’s domestic defense industry. This multi-aligned procurement strategy extends further, encompassing specialized equipment from Belgium and the Netherlands, alongside targeted acquisitions of defense systems from non-Western actors like Iran and China. Together with the European Union’s EUMA monitoring mission, which provides a crucial layer of border observation and confidence-building, this broad supplier network significantly enhances Armenia’s defensive capacity and reduces its vulnerability to singular external leverage. 

Democratic Consolidation and Institutional Reform
Moving closer to Europe tends to bring steady institutional change rather than sudden upheaval. The EU’s normative influence encourages democratic reforms, a stronger commitment to the rule of law, and credible anti-corruption efforts. As that momentum builds, Armenia can see greater political stability and better governance.

Enhanced Diplomatic Leverage
This shift can also increase Armenia’s diplomatic leverage. By cultivating a wider and more diverse circle of international partners, Armenia gains strategic breathing room it previously lacked. In regional negotiations, that can translate into a stronger starting position: instead of simply absorbing decisions made elsewhere, Yerevan now has more capacity to shape its own course.

Challenges

The Security Vacuum
Armenia’s pivot away from Moscow is no longer a gradual process; the old security architecture has already collapsed. Crucially, Yerevan’s evolving security calculus no longer views Russia merely as an unreliable guarantor, but increasingly as a source of insecurity. With the illusion of a Russian security umbrella gone, Armenia now operates in a fundamentally different strategic environment. Its growing network of partners, from Washington and Paris to New Delhi, can provide significant technological and logistical support. But because these relationships stop short of a formal defense alliance, Armenia must continue to absorb regional pressures as its multi-aligned security architecture takes shape.

Economic Dislocation and Russian Retaliation
Economic risks remain substantial. Armenia’s longstanding dependence on Russian trade and energy infrastructure leaves it vulnerable to asymmetric pressure. Yet the geo-economic environment is evolving faster than earlier expectations anticipated. This became clear in mid-2026, when Moscow imposed sweeping import bans on Armenian agricultural goods, brandy, and mineral water. Contrary to initial projections of prolonged dislocation, the coercive move prompted a rapid, institutionally robust response from the European Union. Through emergency Autonomous Trade Measures that liberalized nearly 80% of Armenian exports, Brussels effectively granted the EU single market access to 99% of Armenia’s fresh produce and more than 90% of its beverage exports previously destined for Russia. While Moscow still retains the capacity to use its market as an instrument of political pressure, the episode underscores a broader structural development: trade diversification hurdles long cited as prohibitive are being overcome quickly through coordinated Western institutional engagement.

Internal Political Polarization
Domestically, a foreign policy pivot of this magnitude can introduce profound systemic strain by widening existing societal fractures. While the state apparatus may project a unified executive voice in support of a westward trajectory, deep polarization between pro-Russian and pro-Western factions fragments the broader domestic discourse. This absence of broad domestic consensus is a major obstacle to long-term strategic execution, as polarization continuously threatens the continuity of the state’s grand strategy. 

Conclusion: Navigating the New Geopolitical Constellation

Armenia’s effort to navigate the shifting currents of the emerging global order is useful for understanding small-state agency. Yerevan is not merely absorbing the weight of great-power competition; it is actively working to reposition itself geopolitically through a policy of calculated strategic diversification. This approach goes beyond reactive hedging. It reflects a deliberate logic: turning structural vulnerabilities into usable strategic assets.

Viewed through the Three Seas System prism, Armenia’s fate is not determined solely by geography. What matters more is whether it can function as a meaningful node within an evolving network of connectivity. Russia’s once-dominant influence is receding. The United States has advanced initiatives like TRIPP, while Europe’s normative and economic pull continues to intensify. Together, these forces create a layered, multi-vector environment. The decisive test will be how deftly Armenia manages these competing pressures, using each to bolster sovereignty, strengthen the economy, and preserve security.

None of this comes without cost. A security vacuum has opened, and economic disruption is a real possibility. Yet this pivot also unlocks opportunities that were previously out of reach: stronger democratic institutions, a genuinely diversified economy, and access to more reliable security partners. 

If realized, Crossroads of Peace could fundamentally reshape regional connectivity, pulling Armenia out of its landlocked isolation and into a central transit role. The payoff would be more than financial. Embedding Armenian security in the interests of a broader international community could create a form of protection that geography alone has never provided.

What happens in Armenia will ultimately test whether smaller states can adapt, and perhaps even prosper within a fractured international order. Its ability to sustain a flexible foreign policy, balancing hard-nosed pragmatism with a consistent commitment to self-determination, will determine whether it becomes a key player in the Three Seas mega-region or remains exposed to the turbulence of great-power rivalry.
