Revenge as a leadership strategy
It works very well, until the "leader" using revenge as a tool is in the "petitioner" position. At that point, the gratitude inspired by such a strategy will become evident in its implementation by those upon which it was formerly employed.
In other words, if we would have a civilized world, we need to set a civilized example.
That's what made the Marshall Plan the success it was. Too bad most of the people who remember when we acted like that are dead or dying now.
