"Combining these estimates suggests Darfur’s death toll now hovers at 200,000 — just half of what Save Darfur claimed a year ago in its ad and still claims on its Web site. Of course, whether 200,000 or 400,000 have died, the need to resolve the conflict in Darfur is the same. But Save Darfur’s inflated estimate — used even after Dr. Hagan revised his estimate sharply downward — only frustrates peace efforts."
