What is the biggest threat to world peace?

[Gandalf]

Water. I remember my dad telling me as a kid that water would cause ww3. Of course I told him he was crazy.

Very good. That will be the next craze after oil is done with.

I'd wager it comes before the oil runs out and that oil will fuel the war it starts.

I won't disagree. All I know is I am in the wrong century.
