Russia and Belarus conduct Zapad-2025 drills near NATO’s eastern flank, with Lithuania citing long-term security risks.

The joint Russian-Belarus military exercise Zapad-2025 was reported to involve up to ~30,000 troops (according to Lithuanian military intelligence) with several thousand of them positioned in Belarus, and some Russian personnel in or around the Kaliningrad exclave which borders Lithuania. The exercise scope explicitly included simulation elements for the planning of use of Russian tactical nuclear weapons and Oreshnik intermediate-range missiles according to media analysis. From Lithuania’s perspective this is a direct threat because such drills adjacent to Lithuanian territory raise the possibility of rapid mobilisation, testing of invasion corridors (especially via Kaliningrad or Belarus) and deployment of dual-use systems. The exercise therefore falls under your classification of “construction of military or dual use facilities; transfer of troops / weapons; military drills.” The proximity to Lithuania’s border magnifies the risk: the Kaliningrad region and Belarus form a pincer or staging base area opposite Lithuania’s eastern/western flanks. The dynamics reveal how Russia uses large-scale drills not just for training but for signalling, for rehearsal of forces close to NATO flanks, and for indirect coercion by demonstrating readiness.
