Bulgarian Prime Minister Rumen Radev has repeatedly advocated for diplomatic solutions to the war in Ukraine, warning against the risks of military escalation. In early September, Radev cautioned that pursuing a conventional military victory against a nuclear power could lead to uncontrolled tension with Moscow. He specifically questioned the provision of long-range weapons to Ukraine and emphasized that “diplomacy is the only sustainable and reliable solution to the conflict.”

By late September, Radev’s focus expanded to include the broader implications for European security architecture. Speaking in Brussels, he noted that Russia utilizes nuclear rhetoric when it perceives weakness and urged the international community to remain prepared for dangerous scenarios. He maintained that while support for Ukraine is necessary, the ultimate objective must be creating conditions for peace through communication and mutual listening.

On September 30, Radev expanded his warnings at a defense and space forum in Brussels, noting that radio signal jamming and spoofing related to the conflict are causing daily disruptions to air traffic control over the Black Sea. He argued that the current strategy of continuous military aid is insufficient for peace and urged the European Union to prepare for worst-case scenarios involving Russia’s nuclear arsenal. 

Addressing accusations that his position is pro-Russian, Radev denied the claims, stating his priority is a “realistic approach” to end a war of attrition that is draining social and economic systems. Concurrently, Ukrainian Foreign Minister Andrii Sybiha reported that intelligence has identified Russian plans to conduct attacks against EU member states, characterizing Russia’s subversive activities as moving beyond traditional hybrid warfare to weaken European support for Ukraine.
