Once upon a time there was an evil dictator who gassed his subjects and brought starvation and war upon them. After being beaten in war, he continued to lavish money on building new weapons, nerve gas, weapons of germ warfare. and atomic bombs. But it was done in secret so that no one could be sure what he was doing or where.
One day, the President said "This is an evil man who threatens world peace and supports terrorism. Who will help me rid the world and his poor nation of him?"
"Not I!" said the Saudis and the other Arab states.
"Not I!" said the French, the Belgians and the other Europeans.
"Not I!" said the Russians.
"Not us!" cried the academics.
"Then we'll do it ourselves!" said the President. And he did.
