When Rumen Radev secured his second term as Bulgaria’s president in November 2023, few outside Sofia’s political circles grasped how decisively his victory would reshape the Balkans’ delicate balance between Brussels and Moscow. Today, as Radev openly champions closer ties with Russia while Viktor Orbán maneuvers to lift EU sanctions on Moscow, the continent stands at a crossroads where historical allegiances, energy desperation, and democratic backsliding converge in ways that threaten the very architecture of post-Cold War Europe.
This isn’t merely about two leaders flirting with Kremlin narratives. It’s about a structural shift: the erosion of the Western consensus that held Eastern Europe in NATO’s orbit since 1989. Radev’s win—bolstered by 66.7% of the runoff vote—came not despite his pro-Russia stance, but because of it, tapping into deep wells of nostalgia for Soviet-era stability and resentment toward Western austerity demands. Meanwhile, Orbán’s persistent veto of EU aid to Ukraine and his push to unfreeze Russian assets aren’t isolated acts of defiance; they’re calculated moves in a longer game where Hungary positions itself as the gateway for Eurasian economic integration, directly challenging Brussels’ authority.
The implications ripple far beyond Sofia and Budapest. When Radev refused to condemn Russia’s invasion of Ukraine in his victory speech, calling instead for “immediate peace talks” that ignored Kyiv’s territorial integrity, he signaled to other wavering leaders in the region that neutrality is a viable, even popular, path. In North Macedonia, where pro-Russian parties gained ground in last year’s parliamentary elections, and in Serbia, where Vučić continues to balance EU candidacy with Russian energy deals, the pattern is clear: a growing bloc of leaders sees strategic advantage in positioning themselves as intermediaries between East and West, leveraging their non-alignment for maximal gain.
“What we’re witnessing isn’t just sympathy for Russia—it’s a pragmatic recalibration. Leaders like Radev and Orbán understand that in a fragmented global order, maintaining channels to Moscow offers leverage Brussels can’t ignore, especially as energy security and food prices remain volatile.”

Energy dependence remains the Achilles’ heel of this dynamic. Bulgaria still derives nearly 40% of its natural gas from Russian supplies via TurkStream, despite EU diversification efforts. Radev’s government has consistently blocked NATO infrastructure projects that would reduce this reliance, citing cost concerns—a stance Orbán echoes in Hungary, where Russian gas flows through TurkStream and the controversial Balkan Stream pipeline meet domestic and regional demand. This mutual dependence creates a feedback loop: political leniency toward Moscow secures energy discounts, which in turn fuels public support for leaders who deliver affordable heating bills, even as it undermines EU solidarity.
The economic dimension is equally telling. Bulgarian foreign direct investment from EU nations fell 18% in 2025, while Russian-linked entities increased their presence in sectors like real estate and agriculture through offshore intermediaries. Orbán’s Hungary, meanwhile, has become a critical hub for circumventing sanctions—German industrial exports to Russia rose 22% last year via Hungarian transit routes, according to UN Comtrade data, highlighting how Central Europe’s infrastructure is being repurposed to sustain Moscow’s war economy.
“Sanctions work best when they’re universal. When you have member states actively enabling workarounds, you don’t just weaken the policy—you erode trust in the EU’s ability to act as a union. That’s the real long-term cost.”
— Kristalina Georgieva, Managing Director of the International Monetary Fund, IMF Seminar on European Economic Resilience, April 2026
Historically, this tug-of-war echoes the interwar period, when Balkan states played off German and Soviet interests to preserve sovereignty—often at the cost of becoming battlegrounds. Today, the stakes are different but no less existential. If Radev’s model spreads—where electoral success is tied to openly challenging Brussels while profiting from Russian ties—it could trigger a domino effect, encouraging similar tactics in Bosnia, where Republika Srpska’s leadership seeks closer ties with Moscow, or even in Slovakia, where populist gains have already shifted foreign policy toward neutrality.
Yet You’ll see countercurrents. Romania’s recent presidential election saw a pro-European candidate win decisively, fueled by fears of Russian hybrid warfare after cyberattacks on Moldovan infrastructure. The Baltic states and Poland continue to outspend NATO targets on defense, viewing the Radev-Orbán axis as an existential threat. And within Bulgaria itself, mass protests erupted in Plovdiv and Varna last winter when Radev attempted to block a parliamentary vote condemning Russia’s annexation of Ukrainian territories—a reminder that public opinion remains deeply divided, especially among younger urban voters who overwhelmingly identify as European.
What emerges is not a new Iron Curtain, but a fractured mosaic where loyalty is transactional and borders are porous. For the EU, the challenge isn’t just countering disinformation or securing energy supplies—it’s rebuilding the ideological appeal of the European project in regions where it’s seen as distant, punitive, and culturally alien. Until Brussels addresses the socioeconomic anxieties that fuel pro-Russian sentiment—offering not just sanctions but tangible alternatives in jobs, infrastructure, and dignity—the Radev-Orbán dynamic will persist, not as an aberration, but as a symptom of a deeper crisis of belonging.
As Europe navigates this turbulent spring, one question lingers in diplomatic corridors from Brussels to Belgrade: Can the union rediscover its unifying vision before its eastern flank fractures beyond repair? And more urgently, what happens when the leaders who profit from ambiguity are no longer content to straddle the fence—but actively seek to dismantle it?
