U.S. sanctions - though critical - are being heard by the people, catching attention towards corrupt presidents like Haiti's Michel Martelly.
Sanctions on entire countries (like Cuba, Iran and Venezuela) tend to be counterproductive as they create widespread misery but also strengthen autocrats' grip on power.
Sanctions on specific individuals (like the former president of Haiti) can be effective. Though they might not change behavior, they send a strong signal and impose a stigma.
Targeted sanctions can provide more opportunities to change the status quo. Once imposed, they give the United States a valuable bargaining chip.
Examples in Guatemala, Latvia and Ukraine show how sanctions against specific individuals can produce swift results.
In countries that don't mind antagonizing Washington, victories are fragile and changes elusive.
The United States needs to seek alternatives in dealing with situations like Venezuela, where President Maduro has refused to give up power despite sanctions and elections.
Conclusion: Although they are not perfect nor the only solution, sanctions are a key tool in the fight against corruption and impunity. Additionally, they offer hope to activists fighting for justice in their countries.
