Focusing on the European Union’s sanctions policy against Russia from 2022 to 2025, this chapter critically reassesses the strategy’s effectiveness and wider geopolitical ramifications. It contends that the sanctions, intended to undermine Russia’s war effort and compel a negotiated resolution, have failed to achieve their stated objectives and have revealed the structural incoherence of the EU’s geopolitical orientation. Positioned as instruments of coercive diplomacy, the sanctions have highlighted the limitations of Western economic statecraft in the context of Russia’s demonstrated economic resilience, its pivot towards non-Western trading partners, and the rapid consolidation of a wartime economy. The analysis underscores that the EU has absorbed disproportionate economic consequences, ranging from energy disruptions to industrial stagnation, raising critical concerns about the strategic judgement underpinning its policy choices. The chapter further examines the EU’s diminishing diplomatic influence, notably its exclusion, alongside Ukraine, from the 2025 ceasefire negotiations led by the United States. In conclusion, the chapter argues that the sanctions have entrenched rather than mitigated the cycle of escalation, and that the EU’s continued adherence to a faltering strategy underscores the pressing need to redefine its role in the post-war international order.
