D'un point de vue statistique, l'Irak et le Darfour sont comparables: même nombre de victimes, même nombre de déplacés.  Pourtant, dans l'opinion publique, ces 2 crises humanitaires sont perçues très différemment.

Un excellent texte du LA Times qui aborde ce double-standard.

Suffering binds Iraq and Darfur

Most people don't support the war because it's not seen as the grave humanitarian crisis that it is.

Polls tell us that Americans want to be less involved in Iraq and more involved in Darfur. It's not hard to understand why. For the American public, and many of its leaders, Iraq is a tainted war without good guys. Darfur, by contrast, is a chance to save the helpless. In our minds, Iraq and Darfur seem to fit into neat categories: One is a botched war, the other is a humanitarian crisis.  […]

Still, persuading Americans to see Iraq as a humanitarian crisis in which we still have a moral obligation is a struggle. We now know the Iraqis almost too well. It was easy to see the Kurds and the Shiites as the brave opponents of a brutal dictator when our warplanes were protecting them from 30,000 feet. It's much harder when U.S. troops have to grapple with their unsavory leaders and their thirst for revenge. Remember the solidarity we felt when Iraqis voted? Those feelings of kinship have given way to a sense of betrayal.

The victims in Darfur, by contrast, remain comfortable abstractions. […]

It's no wonder that Darfur's advocates have chosen to present that conflict as starkly as possible. Recent humanitarian interventions have had identifiable and sympathetic victim groups (think of the besieged Bosnian Muslims and the oppressed Kosovars). For all its suffering, Iraq lacks an identifiable victim group. Neither the Sunnis nor the Shiites have much claim on the American conscience at this point. The Sunnis are erstwhile oppressors, while the Shiites appear to be extremist fellow travelers with Iran. The Kurds have been victimized many times before but, mercifully, they have largely skirted the current bloodshed.

Distaste for the major Iraqi factions is only one reason we don't often think of that conflict in humanitarian terms. Another is the more than 3,000 U.S. troops killed in Iraq and the tens of thousands wounded, many grievously. In the context of that loss, we have little compassion left for the Iraqis. It's a phenomenon we've seen before. […]

It's natural that Americans would yearn for a simpler and clearer conflict than Iraq to showcase their humanitarian impulses. But our concern for Darfur must not become a moral salve that allows us to abandon Iraq to its spasm of violence. There may be no blameless factions in Iraq, but there are thousands of ordinary victims. Unless it is clear that we are doing no good, we owe them more.
