Which holocaust? The one 50 years ago or the one currently happening? http://www.youtube.com/watch?v=dPxv4Aff3IA

So how can politicians prevent a holocaust exactly? I thought they caused it in the first place.

There are a ton of events which rival the Holocaust in horror. In fact, genocides are being committed as we speak.

I recommend you add "Holodomor" next time you make a throwaway account to talk about the Holocaust.
