As I have said before on this blog, humor is a wonderful way of exposing the idiocy of your opponents arguments. Charlie Chaplain and Mel Brooks knew that in their powerful riffs on Hitler.
And now a Swiss cartoonist whose work was reprinted in the International Hearld Tribune has done the same to the Iranian president.
I am unable right now to post a link to it but it essentially showed the Iranian president Ahminajead at a meeting of the IAEA [Int. Atomic Energy Commission] and saying: I would like to announce the Hisoshima cartoon contest. The other people present have their heads in their hands.
It is a commentary on how he and -- to some degree his country -- have become the laughing stock of the world.
