Iran has warned Bulgaria against allowing the United States to use its territory for military operations targeting Iran after Bulgarian Prime Minister Rumen Radev confirmed that Sofia had received a U.S. request to deploy up to eight tanker aircraft at Bezmer Air Base in support of American operations in the Middle East.

The Bulgarian government is expected to submit the proposal to parliament, which will decide whether to authorize the deployment, News.Az reports.

Reacting to the announcement, Iranian Foreign Ministry spokesman Esmaeil Baghaei urged Bulgarian lawmakers not to approve the request, arguing that permitting such a deployment would make Bulgaria an accomplice to actions directed against Iran. He said Tehran expects all countries to avoid becoming involved in military activities that could contribute to further regional instability.

According to Baghaei, Iran considers any logistical or operational support provided for military actions against the country as a matter of national security. He stressed that Tehran reserves the right to defend its sovereignty and territorial integrity against any form of aggression. Iranian officials have repeatedly maintained that states facilitating military operations against Iran should carefully assess the legal and political consequences of such decisions.

The warning comes at a time of heightened tensions in the Middle East, where military deployments and logistical support have become increasingly sensitive issues. Although the reported U.S. request concerns tanker aircraft rather than combat aircraft, Iran views aerial refueling assets as a critical component of modern military operations because they significantly extend the operational range of fighter jets, bombers and surveillance aircraft.

For Bulgaria, the issue has both domestic and international dimensions. As a NATO member, the country regularly cooperates with allied forces, but any decision regarding foreign military deployments is subject to parliamentary approval. The debate is expected to attract close attention from both allies and regional actors because of its potential diplomatic implications.

What is the significance of the reported U.S. request?

The reported U.S. request involves the temporary deployment of up to eight aerial refueling tanker aircraft at Bulgaria’s Bezmer Air Base. Tanker aircraft are designed to refuel military planes during flight, allowing them to remain airborne for longer periods and operate over greater distances without returning to base.

Although these aircraft are not offensive weapons, they play a vital role in virtually every modern air campaign. By extending the range and endurance of combat aircraft, tankers increase operational flexibility and enable long-distance missions. As a result, countries hosting refueling aircraft may become strategically important even if they are not directly participating in military operations.

Bezmer Air Base is among Bulgaria’s principal military facilities and has previously been used during NATO exercises and allied cooperation activities. Its infrastructure makes it suitable for supporting multinational operations, particularly those requiring logistical coordination between Europe and the Middle East.

The request reflects broader U.S. efforts to maintain operational readiness across multiple regions amid continuing instability in the Middle East. Military planners frequently seek access to allied facilities to improve logistical support, ensure rapid deployment capabilities and strengthen coordination with NATO partners.

For Bulgaria, approving such a request would be consistent with its commitments as a NATO ally. However, the decision also carries diplomatic consequences, particularly given Iran’s public opposition and warning that countries supporting operations against it could bear responsibility for their involvement.

Why does Iran refer to international law in its warning?

Iran based its warning on its interpretation of international law, particularly United Nations General Assembly Resolution 3314, which defines acts of aggression. According to Iranian Foreign Ministry spokesman Esmaeil Baghaei, allowing one country’s territory to be used by another state to carry out military aggression against a third country may itself constitute an act of aggression.

Iran argues that this principle extends beyond direct military attacks to include logistical support, such as hosting military aircraft or providing facilities that enable operations against another state. Tehran therefore maintains that countries granting access to foreign military forces involved in actions against Iran could share responsibility for the consequences.

The legal interpretation of such situations remains subject to international debate. While UN General Assembly resolutions provide internationally recognized principles and definitions, governments often interpret them differently depending on the specific circumstances of military operations and existing defense agreements.

NATO members generally view allied military cooperation as part of collective security arrangements established under international treaties. Supporters of these arrangements argue that providing access to military facilities does not automatically make a host country a participant in every operation conducted by allied forces.

Nevertheless, Iran continues to emphasize that any state facilitating military operations directed against it should take into account both legal and political implications. By invoking international law, Tehran seeks to reinforce its diplomatic position while discouraging third countries from supporting future military deployments related to Iran.

How do recent regional tensions influence the dispute?

The dispute comes against the backdrop of continued tensions between Iran, the United States and Israel. Military confrontations, diplomatic negotiations and periods of escalation have shaped regional security dynamics over recent months, making military deployments particularly sensitive.

Iranian officials argue that foreign military infrastructure supporting U.S. operations contributes to regional instability and increases the risk of further confrontation. From Tehran’s perspective, logistical assets such as tanker aircraft, military bases and support facilities form an essential part of broader military planning even when they are not directly involved in combat.

Recent diplomatic efforts have sought to reduce tensions through negotiations, but uncertainty surrounding future talks has remained. As a result, both military preparedness and political messaging have become increasingly prominent components of regional strategy.

The reported U.S. request to Bulgaria has therefore attracted attention beyond the bilateral relationship between Sofia and Washington. Iran views the proposal within the broader context of American military positioning in Europe and the Middle East, while the United States and its allies may regard such deployments as routine measures designed to maintain operational flexibility.

These differing perspectives illustrate how logistical decisions involving allied military facilities can quickly become significant diplomatic issues during periods of heightened geopolitical uncertainty.

What could happen next?

The next step depends on Bulgaria’s parliament, which will consider the government’s proposal regarding the reported U.S. request. Lawmakers are expected to assess the country’s security interests, alliance obligations and broader diplomatic considerations before reaching a decision.

If parliament approves the deployment, relations between Iran and Bulgaria could become more strained. Tehran has indicated that countries participating in or facilitating military operations against Iran should be prepared to accept responsibility for the consequences of those actions.

If the proposal is rejected, the outcome could affect discussions within NATO regarding future logistical planning and military cooperation, while potentially easing diplomatic tensions between Sofia and Tehran.

Regardless of the final decision, the issue highlights the growing importance of military logistics in international security. Access to air bases, refueling capabilities and strategic infrastructure has become an increasingly significant factor in regional military planning, particularly during periods of heightened geopolitical tension.

The debate also demonstrates how decisions taken by individual NATO members can attract international attention when they intersect with broader security developments in the Middle East. Bulgaria’s parliamentary vote will therefore be closely watched by regional governments, NATO allies and international observers alike as they assess its potential implications for both European security and Middle Eastern stability.
