Baltic states continue to assess various hybrid and military threats attributed to Russia. In Lithuania, officials have highlighted vulnerabilities in public resilience, noting low rankings in media literacy. In Latvia, President Edgars Rinkēvičs stated that the risk of a direct Russian invasion remains low, though the country faces threats from cyberattacks, sabotage, and hybrid operations. 

Recent security discussions in Riga, Latvia, have emphasized the necessity of robust defense measures. Latvian Prime Minister Andris Kupčins has called for billions in additional European Union funding to bolster national defenses as the region prepares for potential worst-case scenarios. The security landscape remains complicated by drone incursions, sabotage, and the instrumentalization of migration. Kyrylo Budanov, head of Ukraine’s Office of the President, raised concerns regarding Europe’s response to threats such as cable cuts, arson, and explosive-laden drones.

Experts suggest Russia may favor operating in the ‘gray zone’ to increase political and economic costs for nations supporting Ukraine while avoiding direct military confrontation with NATO. One high-risk scenario identified involves the potential creation of a separatist entity, such as a ‘People’s Republic of Latgale’ in eastern Latvia, mirroring the 2014 Donbass model. In response, Estonia, Latvia, and Lithuania have been implementing the Baltic Defense Line, a system of fortifications and defensive structures along their eastern borders since 2024.
