What a world without U.S. power looks like.

At places like Davos and Harvard, the world's sages rarely stop fretting about the dangers of a too powerful America. Well, if you want to know what the world looks like without U.S. leadership, Exhibit A is Darfur in Sudan.

Today's leading authority on Darfur is the political philosopher Thomas Hobbes, who prophesied a world "nasty, brutish and short." At least 200,000 civilians have been killed in the past three years and two million more have become refugees. The source of the problem is the Arab rulers in Khartoum, who have pursued an ethnic cleansing campaign against black Muslims in western Sudan. They've equipped the Janjaweed Arab tribesmen to do the dirty work, and that militia is now attacking civilians across the border in Chad, creating 20,000 more refugees.

To his credit, Kofi Annan started shouting about the problem two years ago, and former Secretary of State Colin Powell labeled it "genocide" not long after that. The U.N.'s mighty peace-making machinery then started to roll and . . . nothing. The Chinese (who have close commercial ties to Khartoum) and Russians have blocked any serious intervention. Arab members of the Security Council have also opposed any attempt to single out Khartoum.
