Fact Check: Ukrainian Intelligence is Actively Working to Weaken Russia's Military Capabilities

What We Know

Recent reports indicate that Ukrainian intelligence agencies are indeed engaged in operations aimed at undermining Russia's military capabilities, both within occupied territories and on Russian soil. For instance, on June 14, 2025, agents from the Defense Intelligence of Ukraine executed a sabotage operation against a power substation in Kaliningrad, which resulted in significant disruptions to local military facilities and caused an estimated $5 million in damages (source-3). This operation is part of a broader strategy where Ukrainian forces have been increasingly targeting Russian military assets, including air defense systems and military infrastructure, as part of their ongoing conflict (source-4).

Furthermore, a report by the Congressional Research Service outlines the context of the military operations, indicating that Ukraine's military intelligence has been actively involved in operations that extend beyond its borders, targeting Russian military capabilities directly (source-1). This includes the use of drones and other asymmetric warfare tactics to strike at Russian military assets (source-5).

Analysis

The evidence supporting the claim that Ukrainian intelligence is actively working to weaken Russia's military capabilities is robust. The operations described, such as the sabotage of the Kaliningrad substation, demonstrate a clear intent and capability to disrupt Russian military operations (source-3). Additionally, the strategic use of drone attacks on Russian military sites indicates a systematic approach to degrading Russia's military effectiveness (source-4).

However, it is important to assess the reliability of the sources. The reports from defense and intelligence-focused outlets, as well as congressional research documents, lend credibility to the information. These sources are generally considered reliable due to their focus on military analysis and intelligence assessments. However, some sources may carry inherent biases, particularly those that are more politically oriented, such as those from national interest publications (source-5).

Moreover, the implications of these operations suggest a shift in the dynamics of the conflict, as Ukraine's ability to conduct operations within Russia could lead to increased pressure on the Kremlin and alter the course of negotiations (source-4).

Conclusion

The claim that Ukrainian intelligence is actively working to weaken Russia's military capabilities in both occupied Ukrainian territories and within Russia is True. The evidence from multiple credible sources indicates that Ukraine is employing a range of tactics to disrupt Russian military operations, demonstrating both intent and capability in this regard.
