Bulgaria Breaks Russia Front

Seven eastern and northern European leaders signed the Gdańsk declaration on 25 June, naming Russia as the most serious direct and long-term threat to their security. Bulgaria refused to sign (PISM).

That refusal matters because Bulgaria is not a distant bystander. It is an EU and NATO member on the Black Sea, close to Russia's war in Ukraine and exposed to the same strategic pressure that shapes debates in Warsaw, Tallinn and Bucharest. Sofia did not block a military plan or an EU sanction. But it punctured the image of a united eastern flank weeks before the NATO summit in Ankara, and it raised a question every small member state, Malta included, should recognise: when does political signalling become formal decision-making?

A caucus that cannot compel

The Gdańsk format is not NATO taking a collective decision. It is a group of like-minded states trying to push Brussels and the alliance towards a harder line on Russia. Poland, Estonia, Latvia, Lithuania, Sweden, Finland and Romania signed, alongside 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, a wider grouping of eastern NATO members that includes countries with more cautious or divided positions on Russia, Bulgaria among them. The Gdańsk group exists because the B9 could no longer sustain one common 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. But before the formal vote, smaller coalitions set the language, define the threat and try to create political momentum (NATO, Council of the EU). Gdańsk sits in that informal layer. Its power is pressure, not law.

The refusal weakens the signal, not the chain of command

Bulgaria's position does not cancel any treaty obligation or EU measure. NATO's Article 5 mutual defence guarantee remains in place. Germany and the Netherlands were separately taking on a new command role for Estonia and Latvia ahead of the Ankara summit, showing that military arrangements with real operational weight continue regardless of who signs a regional declaration (DW).

The damage is political. For the Baltic states, naming Russia is not diplomatic theatre. Estonia's foreign minister has warned against any settlement that leaves exposed countries at Moscow's mercy (ERR). When a Black Sea ally refuses to name the same threat, Moscow can read uneven political will along the flank, especially as NATO leaders worry they may not be able to rely on US support if Russia attacks (The Guardian).

Romanian coverage framed Bulgaria's stance through President Rumen Radev's appeal to national interest, rather than as a breakdown of trust (Digi24). That distinction matters. Bucharest is not treating Sofia as hostile. It is treating it as unreliable on threat language.

Budapest finds cover in Sofia

Hungarian pro-government media quickly folded Bulgaria's refusal into a domestic story. Mandiner presented it as proof that, after Viktor Orbán shifted position, another country had stepped into the outlier role, arguing that vetoes are not a Hungarian speciality (Mandiner).

Portfolio reported that Budapest had unexpectedly allowed progress on opening a new cluster of Ukraine's EU accession negotiations, while Bulgaria separately asked to remove language urging further chapters to open (Portfolio). Bulgaria is useful to Budapest because it lets Hungary look cooperative by comparison.

The formal test ahead

The real test is whether Bulgaria brings its Gdańsk position into rooms where consensus is required. 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 wording, the issue moves from signalling to alliance consensus. If it blocks language in the EU Council during the next sanctions package, it becomes a veto.

Until then, Bulgaria's refusal sits between disagreement and obstruction. The Gdańsk coalition can agree on threat language faster than it can prove that every exposed state will carry that language into binding decisions.
