The U.S.-brokered peace agreement between Azerbaijan and Armenia has set in motion a transformation of the balance of power in the South Caucasus while simultaneously strengthening Washington’s strategic position in the region. The opening of transport links and the launch of new corridors reduce the region’s dependence on external centers of influence, primarily Russia and Iran, and contribute to the emergence of an alternative architecture of security and connectivity.
The agreements have accelerated the institutionalization of the U.S. presence in a region previously characterized by limited formats of engagement. The use of executive authority to bypass outdated assistance restrictions has enabled more active dialogue and reinforced the role of the United States as a key external guarantor of the new arrangements. At the same time, the continued existence of earlier legislative constraints creates uncertainty and requires annual political decisions, reducing the predictability of U.S. policy.
Resistance within Congress largely reflects the inertia of political approaches shaped in the early 1990s under very different regional conditions. These approaches are increasingly seen as factors that objectively constrain U.S. maneuverability and indirectly preserve elements of Russia’s mediating role. Against this backdrop, efforts are intensifying to revise existing provisions in order to give U.S. policy in the region a more stable and long-term foundation.
A central element of the new configuration is the restoration and development of regional communications. Transport corridors are viewed not only as trade routes, but also as platforms for energy, digital, and logistics infrastructure capable of reshaping long-term patterns of dependence. The simultaneous opening of all communication routes is recognized as a critical condition for the sustainability of the peace process and for preventing new imbalances.
In this context, reducing the region’s reliance on Russian infrastructure and mediation acquires particular importance. For both sides of the former conflict, the strategic challenge is increasingly not bilateral confrontation, but adaptation to Russia’s changing role in the post-Soviet space. The development of alternative routes and partnerships is seen as a tool for enhancing the sovereignty of foreign policy decision-making.
Regional dynamics are further complicated by the role of Iran, which perceives increased connectivity in the South Caucasus and the expansion of external involvement as potential risks. Geopolitical considerations in this case outweigh confessional or ideological factors, as demonstrated by previous regional conflicts. Any escalation of instability within Iran could have direct spillover effects across the Caspian and Caucasus regions.
At the same time, the development of east–west routes linking Central Asia with Europe while bypassing Russia is accelerating. Rising cargo volumes, investments in ports and rail infrastructure, and the restoration of links to exclaves are shaping a new logic of regional integration. Control over infrastructure remains largely at the national and regional levels, reducing external vulnerability.
Economic interdependence between former adversaries is gradually complementing the political process. Trade flows, energy supplies, and humanitarian exchanges are viewed as components of long-term stability that extend beyond formal agreements. The reconstruction of reclaimed territories and the establishment of special economic zones provide the material foundation for post-conflict development.
Taken together, these processes are producing a new regional reality in which the South Caucasus is no longer a peripheral arena for competing powers, but is increasingly emerging as an independent hub of transit, production, and political decision-making. In this context, U.S. engagement is becoming structural rather than episodic, while the durability of the agreements reached will increasingly depend on the ability of regional actors to integrate into this expanding network of connections.
