Genocide, How to stop them...? Options

[FoOd]

Okay, I hope this is in the right forum, but I have been wondering,
How can a genocide be stopped?
What is a genocide? Basically for a brief definition, it is the mass murder of a certain race by another certain race.
Take the Holocaust for example. By far, I think in my opinion, was the worst genocide in the world's history, but lets not stray from the topic I was originally planning.

So how can a genocide be stopped?
Killing the leader?
Nuke them out?
Peace treaties?
Full out war?

Ideas would be nice. This was a way to see what some people might think.

In my opinion, there is no certain way to end a genocide. There might be a way that will work for one genocide, but there is no rigid choice that would work for all genocides.

So, how can all genocides be stopped if more were to ever occur?

There is another way to stop genocide...an evil way. Have them succeed in there genocide...that would do it. But of course no one wants that.

That wouldn't be stopping it, that's just ignoring it. Your assuming after the specific race or group has been killed off it would stop, but at that point of success what if it is decided to target another race or group, then what? But i agree, i don't think most people want that either.
