Do Sanctions Still Work?

Economic sanctions are losing their effectiveness as a tool for forcing regime change or altering state behavior, as targeted nations increasingly exploit loopholes, cryptocurrency, and alternative financial markets like China to bypass U.S. pressure. While historical successes like the dismantling of South African apartheid once validated economic statecraft, current efforts against Russia, Iran, and North Korea have largely failed to curb aggression or nuclear proliferation. To address these shortcomings, Senator Richard Blumenthal is pushing a new bipartisan bill that authorizes the use of tariffs as an explicit geopolitical weapon against the top five purchasers of Russian oil. This legislative effort aims to tighten enforcement and create tangible economic consequences for countries facilitating Russian revenue. Ultimately, the success of these measures hinges on rigorous enforcement and the ability of the U.S. to maintain its leverage within the global financial system.
