It looks obvious

What is more shocking is the indifference of the left. Instead of demanding our governments act now, we are told that what is going on in Darfur is none of our business. Or that this is civil war, not genocide. Or that it is far too complicated for us to intervene. Or that any intervention on our part would only make matters worse. Or that we shouldn’t call for intervention because no one has the slightest intention of doing anything, so we are raising expectations that cannot be met. Or that the real plan is to invade Sudan and create a new colony.

These are shameful evasions that run counter to all the left is supposed to stand for. Ever since the Holocaust, if not before, it has been surely the most basic principle for the left to take a stand against state-organised mass killing. We found a name for this crime - genocide. We devised a law against this crime - the genocide convention. But now we are confronted by mass killing again. Whether or not you call it genocide, it is mass murder. The author of the UN report, Antonio Cassese, who reluctantly decided it might not technically, absolutely qualify as genocide, specifically concluded that actually it made no difference. Above all, he said, don’t use this as an excuse not to act.
