Genghis Khan quote

I’ve seen a quote generally attributed to Genghis Khan as follows;

You might have heard Governor Schwarzenegger say it in the historical documentary ‘Conan the Barbarian.’

I’ve never had cause to doubt it as it sounds like sort of conciliatory rhetoric he would employ. However, I just read somewhere else that he never said it at all.

Is there a sure answer one way or the other?

Can’t say whether or not the Khan thing is true, but I’m positive I’ve read a very close variation of that quote in the Conan books. That’d be my guess where it came from. A google search only brought back other message board references. Yahoo search brought back more references to the movie.

Yeah - I guess there are four possibilities;

One - he did say it

Two - his son said it

Three - someone else entirely said it

Four - the whole thing is bollocks
