Secretary-General Annan spoke for all of us ... when he said that ethnic cleansers and mass murderers can find no refuge in the United Nations, no source of comfort or justification in its charter. We must do more to make these words real. Of course, we must approach this challenge with some considerable degree of humility. It is easy to say, "Never again," but much harder to make it so. Promising too much can be as cruel as caring too little. But difficulties, dangers, and costs are not an argument for doing nothing. When we are faced with deliberate, organized campaigns to murder whole peoples or expel them from their land, the care of victims is important but not enough. We should work to end the violence.
