Veto flood against the EU

The situation involves the potential for Croatia to veto Montenegro's EU accession based on specific demands, which is presented as a political instrument amid broader tensions regarding EU veto power. Croatia has put forward eight demands against Montenegro, including compensation related to Yugoslav war prisoners, missing persons investigations, and disputes over maritime borders and assets from the former Yugoslav army. While some of these demands are viewed as justified by Croatia, others are controversial and linked to domestic politics in Zagreb.
The context also involves other accession candidates: Ukraine and Moldova received expedited status, with Hungary exercising a blocking position related to Ukrainian minority rights, which has shifted based on domestic political developments involving Viktor Orbán's successor. North Macedonia experienced prolonged negotiation delays due to disputes with Greece and Bulgaria over state name recognition and minority status, leading to a compromise that remains contested. Serbia is also facing resistance from several EU members regarding accession negotiations, involving conflicts over the war period and broader rule of law concerns. Finally, Albania faces potential intervention from Greece regarding minority rights during its accession process. The overarching discussion is whether to reform the EU's veto system, with proposals for qualified majorities being blocked by the unanimity requirement.

* Montenegro could become an EU member at the beginning of 2028.
* Croatia could exercise a veto against Montenegro's accession if Montenegro does not meet Croatian demands.
* Croatia presented eight demands to Montenegro, including compensation for former Yugoslav prisoners, investigation into missing Croats, and disputes over maritime borders and assets from the former Yugoslav army.
* Hungary blocked the opening of the first negotiation cluster with Ukraine until April 2026.
* Hungary's successor lifted the veto on the initial negotiation cluster but blocked further chapters in June 2026.
* The status of North Macedonia as an EU accession candidate has involved delays from Greece and Bulgaria over state name recognition and minority status.
* A compromise mediated by the EU Council led to the opening of accession negotiations with North Macedonia in July 2022.
* Eight EU member states spoke out against opening further negotiation chapters with Serbia in July 2026.
* Greece has threatened to block Albania's accession if Greek minority rights are not sufficiently protected.

The dynamic presented reveals a systemic tension between the principle of national sovereignty within the EU structure and the mechanisms designed for EU integration, specifically the veto power. The scenario regarding Montenegro demonstrates how national historical grievances and domestic political calculations can be weaponized within an integration framework, transforming accession negotiations into instruments of bilateral leverage rather than objective legal processes. The pattern observed with North Macedonia illustrates how unresolved historical narratives—such as territorial claims or minority status—can sustain deadlock across multiple EU states for decades, demonstrating that procedural solutions are often insufficient without addressing underlying identity politics.
The use of the veto by member states, exemplified by past instances involving Hungary, suggests a vulnerability in the institutional architecture when it is utilized to enforce political agendas rather than procedural adherence. The proposed reform of the veto system, which faces an insurmountable hurdle due to the requirement for unanimous adoption, highlights a structural resistance to altering this mechanism through consensus-based politics. This points to a tension between the desire for streamlined integration and the entrenched power dynamics favoring existing member interests. Furthermore, the situation with Ukraine showcases how internal domestic political struggles can be strategically amplified to shape external EU policy, framing minority rights as a means of asserting national identity against perceived external pressures.
The core implication is that accession procedures are not purely legal exercises; they are arenas where competing national narratives and historical grievances collide under the guise of legal compliance. The focus shifts from assessing whether demands are "justified" to understanding how power is exercised in the process—whether through legitimate negotiation or politically motivated obstruction. What alternative institutional mechanisms could be developed that allow for integration without relying on potentially paralyzing veto politics driven by national self-interest? What costs are incurred when historical disputes become prerequisites for future political integration?
