The appeal of economic sanctions is almost irresistible to democratic governments. They occupy the comfortable middle ground between doing nothing and deploying military force, allowing politicians to demonstrate resolve without body bags. Since the end of the Cold War, their use has exploded — the United States alone maintains sanctions programs against more than two dozen countries, plus thousands of designated individuals and entities. Yet the scholarly consensus on their effectiveness is brutal: comprehensive studies suggest sanctions achieve their stated policy goals roughly one-third of the time, and that figure may be generous.
The gap between sanctions' popularity and their performance demands explanation.
The theory and its discontents
The logic seems straightforward: impose economic costs on a target state, and its leadership will eventually capitulate to avoid further damage. But this model assumes that authoritarian regimes prioritize economic welfare over political survival — an assumption that history repeatedly contradicts. North Korea has endured decades of increasingly severe sanctions while accelerating its nuclear program. Cuba's government outlasted the Cold War, the Soviet Union's collapse, and sixty-plus years of American embargo. Iran's economy has suffered enormously, yet its nuclear ambitions have only grown more sophisticated.
The problem is structural. Sanctions hurt populations broadly but rarely threaten the specific individuals who control policy. Autocrats can redirect scarce resources to regime loyalists, blame foreign powers for economic hardship, and use sanctions as justification for domestic repression. In some cases, sanctions inadvertently strengthen the very leaders they target by eliminating independent economic actors who might otherwise form a political opposition.
When sanctions do work
The minority of successful cases share common features worth noting. Sanctions tend to succeed when the target is a democracy or at least has meaningful domestic political competition, when the demands are modest and face-saving exits exist, when the sanctioning coalition is broad and includes the target's major trading partners, and when the target lacks powerful protectors willing to provide economic lifelines.
South Africa in the late apartheid era met most of these criteria. The regime faced genuine internal pressure, the international coalition was unusually unified, and the demanded change — ending apartheid — while enormous, came with a clear path to reintegration into the global economy. Contrast this with Russia after its invasion of Ukraine: despite unprecedented Western sanctions, Moscow found willing buyers for its energy exports in China and India, and Vladimir Putin faces no credible domestic political threat.
The humanitarian paradox
Perhaps the most troubling aspect of sanctions is their distributional impact. Comprehensive sanctions devastate ordinary citizens — collapsing healthcare systems, creating food shortages, destroying middle-class savings — while political elites typically insulate themselves. The Iraqi sanctions regime of the 1990s may have contributed to hundreds of thousands of excess deaths, predominantly among children, without dislodging Saddam Hussein. This has led to the rise of "smart" or "targeted" sanctions aimed at specific individuals, but these too have limitations: asset freezes mean little to officials who keep their wealth in non-cooperative jurisdictions, and travel bans are symbolic irritants rather than policy-changing pressures.
Our take
Sanctions persist not because they work but because they satisfy domestic political needs in sanctioning countries. They allow governments to be seen acting without the costs of military intervention or the perceived weakness of diplomacy. This is not inherently cynical — sometimes signaling matters, and sometimes sanctions buy time for other strategies. But intellectual honesty requires acknowledging that sanctions are often performative punishment rather than effective coercion. The question policymakers should ask is not "should we sanction?" but "what specifically will these sanctions change, and through what mechanism?" Until that discipline takes hold, sanctions will remain the foreign policy equivalent of rain dances: emotionally satisfying, occasionally coinciding with desired outcomes, and fundamentally misunderstood by their practitioners.
