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?

the holocaust isn't the worst genocide.

no one remembers the armenians. they are lost forever. the turkish genocide succeded, where the nazi genocide failed.

How did they succeed? Armenia is a well country right now . I'm not trying to justify what the Truks did but what im saying is the Armenian race was not killed of . I have two Armenian friends at school .
