C.S. Lewis wrote a wonderful short book in 1941: the screwtape letters, a collection of letters from a senior devil, Screwtape (an Under Secretary in the Lowerarchy), to his nephew Wormwood, an incompetent and very junior devil.

Now, Wormwood writes to uncle Screwtape an extatic letter on their recent successes.

1, We have convinced the Christians in the most militarily powerful nation on the planet to support our causes. The greatest success of this venture has been in convincing the leadership that they are in fact doing the Enemy's work, not ours. Without their energetic support we never would have achieved so much.

If you know the original screwtape letters, go and read this.
