As is being widely reported by the media, the level of violence in Iraq shows no signs of abating; indeed it is worsening.
This outcome should hardly come as a surprise to people> Once the rigid command and control system, that operated under Saddam Hussein, was removed (an nothing effective put in its place) the stresses and tensions of a society governed and held to together by fear would find an outlet.
These "stresses" are being exacerbated by groups with their own agenda.
The question remains, why did the occupying powers not have adequate plans for the aftermath of Saddam's regime?
Nature abhors a vacuum.
