Ding-dong the Witch is Dead?

Crowds of Baghdad citizens cheering on the morning news reminded me of the scene in the movie Wizard of Oz where the Munchkins were cheering and singing “Ding-dong, the witch is dead!”
Is the wicked witch of the East really dead? Did the house (or restaurant/bunker) fall on him? No one on earth knows yet.
But I wonder, is their another “wicked witch” out their ready to exact revenge?
