Rwanda remembers the Holocaust

On the 60th anniversary of the Russian liberation of Auschwitz, people all over the world remembered. One of the most poignant was in Rwanda where they are still trying to come to terms with their own genocide.

Now a phrase bandied about is "Never Again" but I was trying to think of an actual timely intervention that stopped a genocide from happening. I mean Darfur has been festering for several years now, and we got to Bosnia late as well. Can you think of one that the world actually did right?
