I wish I could upvote this a second time solely for the understatement.

It isn't too hard to talk them into wars either - especially if you first talk someone into getting themselves killed in an appropriately provocative way. Or even just the right person.

I don't know whether this is true or not; there seems to be supporting evidence either way. It's true that you can point to many historical events when a seemingly well-placed murder, or just a well-placed word, sparked a major war. However, in many (if not most) of these cases, the local culture was on the brink of war anyway, and thus the well-placed murder wasn't as well-placed as it appeared -- because the critical mass could be achieved by killing virtually anyone, or even simply by doing nothing but waiting a few years for war to erupt.
