"I'm a broken record on Darfur because I can't get out of my head the people I've met there. On my very first visit, 18 months ago, I met families who were hiding in the desert from the militias and soldiers. But the only place to get water was at the occasional well - where soldiers would wait to shoot the men who showed up, and rape the women. So anguished families sent their youngest children, 6 or 7 years old, to the wells with donkeys to fetch water - because they were least likely to be killed or raped. The parents hated themselves for doing this, but they had no choice - they had been abandoned by the world."
He writes today about the way George 'Wimp' Bush has allied America with Cuba, Zimbabwe, Iran, Syria, Venezuela and others "to eviscerate a forthright U.N. statement that nations have an obligation to respond to genocide":
"It was our own Axis of Medieval, and it reflected the feckless response of President Bush to genocide in Darfur. It's not that he favors children being tossed onto bonfires or teenage girls being gang-raped and mutilated, but he can't bother himself to try very hard to stop these horrors, either."
Kristof acknowledges that Bush is certainly not the worst international leader when it comes to Darfur. He is particularly critical of the American media which has repeatedly ignored the murder of an estimated 400,000 people. He draws his readers attention to a powerful advertisement that American broadcasters have refused to air - probably because it shows up the decadence of their priorities. Please watch it.
George W Bush and Tony Blair would have much more moral authority in Iraq if they weren't so reluctant to intervene on behalf of the people of Darfur. But the popular reaction to the liberation of Iraq and the troubles that have ensued - from opponents of the war, like Mr Kristof - have cautioned them. Mr Kristof needs to be consistent and understand that the consequences of intervening in Sudan may throw up echoes of the problems we all witness in Iraq, and of which he is such a critic.
