In an unexpected twist in post-Cold War diplomacy, former U.S. President Donald Trump has stepped into one of Eurasia’s most entrenched conflicts: the long-standing dispute between Armenia and Azerbaijan. The two nations, locked in decades of tension over the Nagorno-Karabakh region, have witnessed multiple wars, most recently the 2020 conflict in which Azerbaijan reclaimed significant territories. While Russia, the traditional power broker in the South Caucasus, has been preoccupied with its war in Ukraine, Trump has seized the opportunity to position himself as an unconventional mediator.
According to sources familiar with the talks, Trump’s mediation effort was launched through discreet backchannel communications beginning in late 2024. His approach differs sharply from the multilateral frameworks used by the OSCE Minsk Group, which for decades failed to secure a lasting peace. Instead of relying on lengthy diplomatic communiqués, Trump has reportedly offered a package deal mixing economic incentives, infrastructure investments, and potential U.S. energy partnerships.
The Stakes for Armenia and Azerbaijan
For Armenia, the deal could be a lifeline. Still reeling from military defeat and disillusioned by Moscow’s limited assistance during the 2020 war, Yerevan has been increasingly open to diversifying its alliances. The proposed agreement includes U.S.-backed investment in transportation corridors, technology hubs, and energy grid modernization. This could reduce Armenia’s dependency on Russian security guarantees and open pathways toward Western markets.
Azerbaijan, flush from its military victories and strengthened control over key territories, is keen to cement its role as a vital energy corridor linking the Caspian Sea to Europe. Trump’s peace plan reportedly includes incentives for U.S. companies to invest in Azerbaijani infrastructure and oil and gas exports — a prospect Baku sees as enhancing its international legitimacy and expanding its influence in the global energy market.
A Shift in Regional Power Dynamics
What makes this development particularly significant is the sidelining of Moscow. For decades, Russia has been the undisputed arbiter in the Armenia–Azerbaijan dispute, deploying peacekeepers and leveraging its military alliances. Trump’s involvement, especially if successful, would mark a historic shift — one where U.S. diplomacy supplants Russian dominance in the South Caucasus.
However, Russia is unlikely to remain passive. Analysts suggest the Kremlin may respond by tightening military cooperation with both states, offering security guarantees, or ramping up its own mediation initiatives to maintain influence.
Skepticism and Criticism
While some diplomats praise Trump’s bold, unorthodox diplomacy, others warn that his approach risks prioritizing rapid political wins over building durable institutional frameworks. “Peace in Nagorno-Karabakh is not just about signing a document,” says Leila Abashidze, a regional conflict resolution expert based in Tbilisi. “It requires sustained trust-building, demilitarization, and international monitoring — none of which can be achieved through a single high-profile negotiation.”
Moreover, there are concerns about transparency. Details of Trump’s proposal remain undisclosed, fueling speculation that the deal may involve trade-offs that could alienate parts of either society. Both Armenian and Azerbaijani opposition groups have already voiced suspicion, with some accusing their governments of rushing into an agreement without adequate public consultation.
International Reactions
In Europe, reactions have been mixed. The EU, which has invested heavily in its own Armenia–Azerbaijan mediation initiatives, sees Trump’s entry as both a potential breakthrough and a challenge to its influence. Meanwhile, Turkey, a staunch ally of Azerbaijan, has cautiously welcomed the development, seeing it as a possible route to greater regional stability — provided Ankara’s interests are safeguarded.
The Biden administration has kept a measured distance from Trump’s efforts, avoiding direct criticism while signaling that any peace process should align with broader U.S. foreign policy objectives.
What’s Next?
Negotiators are expected to meet in neutral territory later this year, with a possible signing ceremony envisioned in Washington. Observers say the ultimate test will be whether Trump’s deal can translate into tangible changes on the ground — safe return of displaced people, reduction of military deployments, and opening of long-blocked transportation routes.
If successful, the agreement could become a rare example of high-stakes, personality-driven diplomacy yielding lasting results in a post-Soviet conflict zone. If it fails, it risks joining the long list of short-lived ceasefires that have characterized the region for decades. For now, the South Caucasus stands at a delicate crossroads — where shifting alliances, geopolitical rivalries, and the ambitions of a former U.S. president intersect in a bid to write a new chapter in one of the world’s most persistent territorial disputes.
