She needs something more than a slap on the wrist.
To reiterate my thoughts on Karpinski:
In the glory days of the Royal Navy, orders directing an officer to take command of a ship concluded with "Fail not in this charge at your own peril." And their Lordships were in deadly earnest about that.
IMNHO, Karpinski should be executed pour encourager l'autres.
Random execution of generals who fail is not something I would support. I wouldn't want to get into the situation of Russia circa 1942.
However, in this case, BG Karpinski did more than fail. Once she failed, she attempted to deflect blame, etc.
I agree with you. Execution is likely appropriate for her, and she should be brought to trial. The military and war are not just management exercises for Klinton's Korps to play at. General officers have impact on many lives, and they MUST be responsible personnel.
