This book analyzes the goals of Western sanctions imposed on Russia from 2014 to 2023. It explores the effects of sanctions on the Russian economy and its political course, as well as the repercussions of the sanctions to the senders and third parties, including spillover effects on neighboring countries and boomerang effects on the senders. While sanctions can be considered relatively effective in terms of economic damage, the Russian economy is far from being crushed. Importantly, sanctions proved to be ineffective as an instrument of foreign policy. They have failed to alter Moscow's resolve to continue its military operation and are unlikely to change it in the near future. The effects of the sanctions extend well beyond their anticipated impact on Russia itself, primarily due to the Western nations' limited experience and knowledge in implementing sanctions against a major power with extensive global connections, such as Russia.
