The Bosna Fault: The Serb Republic and the Struggle for Geopolitical Power

Bosnia and Herzegovina is experiencing one of its most serious political crises since the 1995 Dayton Agreement. This crisis threatens the fragile state structure that has persisted since the Yugoslav Wars and is fueling a spiral of instability in southeastern Europe. The escalating conflict between the central government in Sarajevo and the Serb-majority entity, the Republika Srpska (RS), is evolving beyond a mere internal dispute into a geopolitical flashpoint where the strategic interests of Russia and the European Union (EU) collide.

Under the leadership of pro-Russian Milorad Dodik, the RS administration is conducting a systematic campaign of institutional defiance that challenges the foundations of the Bosnian state and the international framework designed to uphold it. In contrast, the European Union supports Bosnia’s territorial integrity and a government aligned with its accession process. How did the 30-year peace process arrive at this point?

To understand the current situation, one must first examine Bosnia’s post-war governance structure. The Dayton Accords established a highly decentralized and complex government system, effectively creating a single state composed of two largely autonomous entities: the Federation of Bosnia and Herzegovina (FBiH) and the Republika Srpska (RS), alongside the autonomous Brčko District. The state is divided along ethnic lines, with the central government retaining only a tripartite presidency and a Council of Ministers, while the bulk of political power—including administration, policing and taxation—has been devolved to the entities. The FBiH is further complicated by its division into ten cantons, each with its own government. This layered and intricate system, overseen by the Office of the High Representative (OHR), was designed to balance the interests of Bosniak, Serb and Croat communities and ensure peace, but it has led to sluggish decision-making and a fragmented political landscape.

The current political crisis has been significantly intensified by legal proceedings against RS President Milorad Dodik. In February 2025, the Bosnian state court found Dodik guilty of defying the decisions of the international High Representative Christian Schmidt. The court sentenced him to one year in prison and banned him from holding political office for six years. This ruling was upheld by the appeals court on 1 August 2025. The Bosnian state court later converted the one-year prison sentence into a monetary fine of approximately 18,660 euros but upheld the decision to remove Dodik from the RS presidency and bar him from political activity. Following the court’s final ruling, the Central Election Commission of Bosnia and Herzegovina (CEC) formally revoked Dodik’s mandate as RS president on 6 August. In the face of a political vacuum and Dodik’s refusal to step down, the CEC announced that early presidential elections would be held in the Republika Srpska on 23 November 2025.

Dodik publicly rejected both the court’s ruling and the CEC’s decision, declaring that he would remain in office with the support of Bosnian Serb parliamentarians. The RS National Assembly (RSNA) swiftly endorsed this stance. On 22 August, the RSNA voted to reject the CEC’s decision, oppose the early presidential election and demand that Dodik continue serving as president. Furthermore, the RSNA approved a referendum to be held on 25 October 2025, asking citizens whether they recognize Dodik’s conviction and the authority of the High Representative. This move was criticized by the EU for undermining the rule of law by submitting a court ruling to a popular vote. Dodik has also initiated a government reshuffle within the RS to build a broader ruling coalition and consolidate his power.

Geopolitical Chessboard: Russia’s Role and Western Divisions

The crisis in Bosnia has been further deepened by profound geopolitical divisions within the United Nations Security Council. Russia has firmly backed Dodik, providing him with significant political support. Moscow views the High Representative as the primary source of instability and accuses Schmidt of escalating tensions and interfering in Bosnia and Herzegovina’s internal affairs. Both Russia and China refuse to recognize Schmidt’s authority and demand the closure of the OHR, labeling it an illegitimate relic of foreign oversight. Russia’s strategy aims to foster instability, leverage its historical ties with Serbia and the Republika Srpska, and obstruct the Western Balkans’ integration into the Euro-Atlantic community.

In contrast, Western powers—including the P3^【1】 (France, the United Kingdom and the United States) and the EU—support Bosnia and Herzegovina’s sovereignty and territorial integrity. They regard Dodik’s actions as a dangerous challenge to the rule of law and the Dayton framework. The EU has particularly emphasized the necessity of respecting the court’s rulings. However, signs of potential fissures within the Western stance are emerging. The Trump administration in the United States has adopted a more ambivalent position toward the OHR, in contrast to the EU’s strong backing of Schmidt, and has aligned itself more closely with the views of Russia and China, adopting a politically isolationist posture. This division could weaken the international community’s ability to present a united front if the crisis deepens.

Strategic Objective: Return to the Original Dayton

Although Dodik’s rhetoric is often secessionist, his strategic goal may be more nuanced than an immediate declaration of independence. Analysts argue that his campaign seeks to force a return to the “original Dayton Accords” — the framework that existed before the High Representative used the “Bonn Powers” to establish and strengthen central state institutions. The aim is to reverse decades of state-building, grant the RS a high degree of autonomy, effectively paralyze the central government and eliminate all international oversight. By challenging the state court, the OHR and other national institutions, Dodik is attempting to create a political reality in which the RS functions as a state within a state and holds a de facto veto over all national policies.

Rather than pursuing a direct independence referendum, achieving a high degree of autonomy for the Serb minority by dismantling the state-building process initiated over the past decades and rendering the central government powerless — thereby eliminating all international oversight — appears to be a more attainable medium- to long-term objective. Dodik is attempting to establish a political reality in which the RS operates as a state within a state and holds a de facto veto over all national policies by challenging the state court, the OHR and other national institutions.

Ideologically, the political maneuvers in the Republika Srpska are rooted in an ethno-nationalist doctrine that can be termed the “Srpski Svet” or, in Turkish, “Sırp Dünyası.” This concept mirrors Russia’s “Russkiy Mir” (Russian World) ideology, advocating the political and cultural unification of all Serbs under a single sphere of influence, regardless of state borders. This ideology views Serb populations in neighboring countries such as Bosnia and Herzegovina, Montenegro and Kosovo not as citizens of those states but as integral parts of a single, indivisible Serb nation that must remain aligned with Belgrade. The influence of this ethno-nationalist ideology among the Serb minority undoubtedly carries the potential to heighten tensions between Serbia and Bosnia and Herzegovina.

An Uncertain Future and Implications for European Security

The Bosnian government is trapped in a dangerous impasse. Efforts to enforce the law and detain Dodik risk triggering widespread unrest and further radicalizing RS leadership. Yet accepting this challenge would weaken the Bosnian state and set a precedent for its disintegration.

From a defense perspective, the stability of the Western Balkans is directly linked to broader European security. The EU-led peacekeeping mission, EUFOR ALTHEA, remains a crucial deterrent and is expected to have its mandate renewed in October. NATO also maintains a headquarters in Sarajevo and exerts significant presence through its KFOR mission in neighboring Kosovo. These forces are theoretically sufficient to control localized violence but cannot substitute for a political solution. A broader conflict in Bosnia and Herzegovina would create a serious security vacuum, potentially triggering mass migration flows and enabling malign actors — particularly Russia — to exploit the instability. The crisis clearly reminds the world that peace in the Balkans is not self-sustaining and depends on a fragile balance between domestic politics and international resolve.
