Annan: Darfur genocide nearly halted ... no one left to kill

The U.N. keeps such close tabs on its own ineffectuality these days, I'll have to find something else to do.

Violence in Sudan's Darfur region has diminished greatly over the past year, partly because militia have run out of targets after razing countless villages, U.N. Secretary-General Kofi Annan said.

"The decrease in attacks on civilians may also be a function of a reduced number of targets," Annan said. "So many villages have been destroyed since the war began that there are now fewer locations for militia to strike."

Two things are happening here. First, Arab aggression has succeeded in exterminating or driving out much of the population of Darfur. Second, and rather obviously, the rate of extermination and eviction will necessarily decline as they progress unimpeded. Reuters finds the second fact more significant than the first:

Or, as Leonard Cohen puts it in "The Future":

It's lonely here, there's no one left to torture.
