What did Saddam Hussein's swift execution following his conviction for mass murder have in common with Francis Ford Coppola's Godfather I and Godfather II cinema epics?

The comparison became evident after analyzing the history of U.S. involvement in Iraq alongside two films underscoring the importance of the Mafia's code of silence, omerta.  

Omerta's application relates to individuals not revealing information concerning how The Family does business.  It also tenaciously enforces a rule of silencing individuals perceived as occupying positions to do the organization harm.

From the moment of Saddam Hussein's capture it became evident that the prevailing powers, meaning the Cheney-Bush Administration along with the international consortium to which it is inextricably linked, such as Skull and Bones, the Carlyle Group, along with vital corporate operations such as Halliburton and Bechtel, were not about to let the situation get out of hand.
