Bulgaria Breaks Russia Warning Front

Seven leaders from Europe’s north and east gathered around the same sentence in Gdańsk on 25 June: Russia, they said, is the most serious direct and long-term threat to their security. Bulgaria would not sign (PISM).

That matters less because of what Sofia stopped, and more because of what it exposed. Bulgaria is an EU and NATO member on the Black Sea, close enough to Russia’s war in Ukraine for the geography to do its own arguing. Its refusal did not block a military plan or derail an EU sanction. But it punctured the image of a single eastern flank just weeks before the NATO summit in Ankara, and left the rest of Europe with a familiar question: when does political signalling start to harden into formal policy?

A caucus that cannot compel

The Gdańsk format is not NATO speaking as one. It is a smaller group of states trying to push both Brussels and the alliance towards a firmer line on Russia. Poland, Estonia, Latvia, Lithuania, Sweden, Finland and Romania signed, along with European Commission President Ursula von der Leyen and EU Defence Commissioner Andrius Kubilius (PISM, Euronews).

The Polish Institute of International Affairs draws a clear line between this platform and the older Bucharest Nine, the broader eastern NATO grouping that includes states with more hesitant positions on Russia, Bulgaria among them. The Gdańsk group exists because the B9 could no longer reliably produce a shared threat assessment.

This is how Europe often works. NATO decisions require consensus among all allies. EU sanctions need unanimity in the Council, meaning every member state has a veto. Before either institution reaches that point, smaller coalitions try to define the problem and set the political weather (NATO, Council of the EU). Gdańsk belongs to that informal layer. It can apply pressure. It cannot command.

The refusal weakens the signal, not the chain of command

Bulgaria’s stance did not cancel any treaty obligation or EU measure. NATO’s Article 5 guarantee, the mutual defence clause, remains in place. Germany and the Netherlands were separately taking on a new command role for Estonia and Latvia ahead of the Ankara summit, which shows that practical military arrangements continue regardless of who signs a regional declaration (DW).

The damage is political. For the Baltic states, naming Russia is not a flourish. Estonia’s foreign minister has warned against any peace settlement that leaves exposed countries living under Moscow’s terms (ERR). When a Black Sea ally refuses to use the same language, Moscow can read the gap as evidence that political will on the flank is uneven, even as NATO leaders worry they may not be able to count on US support if Russia attacks (The Guardian).

Romanian coverage treated Bulgaria’s position through President Rumen Radev’s appeal to national interest, rather than as a full breakdown of trust (Digi24). That is a telling distinction. Bucharest is not presenting Sofia as hostile. It is treating it as unreliable on the language of threat.

Budapest finds cover in Sofia

Hungarian pro-government media quickly folded Bulgaria’s refusal into its own domestic story. Mandiner framed it as proof that, after Viktor Orbán shifted position, another country had taken over the role of outlier, arguing that vetoes are not a Hungarian speciality (Mandiner).

Portfolio reported that Budapest had unexpectedly allowed progress on opening a new cluster in Ukraine’s EU accession talks, while Bulgaria separately asked to remove language urging further chapters to be opened (Portfolio). Bulgaria is useful to Budapest because it lets Hungary look constructive by comparison.

The formal test ahead

The real test is whether Bulgaria brings the Gdańsk position into rooms where unanimity is needed. Allies were still finalising common language on Russia for the Ankara summit declaration, where every NATO member must agree (European Pravda). If Sofia blocks that language, the issue becomes a consensus problem. If it blocks wording in the EU Council during the next sanctions package, it becomes a veto.

For now, Bulgaria’s refusal sits between disagreement and obstruction. The Gdańsk coalition can agree on the wording of the threat faster than it can prove every exposed state will carry that wording into decisions.
