For decades, Western leaders have sold economic sanctions as the enlightened, “civilised” alternative—precise, bloodless, and morally superior to military force. A landmark 2025 study in The Lancet Global Health destroys that illusion with devastating evidence. Sanctions are not a scalpel; they are a slow-acting weapon of mass destruction that kills on the same scale as full-scale invasions.

Francisco Rodríguez, Silvio Rendón and Mark Weisbrot have produced what may be the definitive autopsy. Their paper, the most exhaustive ever published, tracked age-specific mortality across 152 countries from 1971 to 2021—fifty years of granular death data spanning infants to the elderly.

They fused every record with the world’s most authoritative sanctions database, then deployed four rigorous causal-inference techniques to eliminate doubt: exact matching that made sanctioned and non-sanctioned nations statistically identical; year-by-year event studies that mapped death-rate trajectories before and after sanctions; reverse-causality tests proving future sanctions could not predict today’s deaths while past sanctions clearly did; and a natural experiment leveraging United Nations voting patterns to........
