Moral ambiguity becomes an excuse for lack of action in Darfur as some claim that the situation is "not as simple as we thought" two years ago when President Bush declared it a genocide.

It is not acceptable to be immobilized by ambiguity, not when women are being raped, children starved, people driven from their homes, routinely slaughtered. Much of life is inherently ambiguous. So if not now, when?
