Is General Pace, on his way out as JCOS Chair, singing a different Iraq tune?

Soon to be former Chairman of the Joint Chiefs of Staff, General Peter Pace, a STRONG supporter of the Iraq war, is now gearing to sing a different tune, by urging President Bush to DRASTICALLY cut troop strength in Iraq.

What is it with these folks? Why can't they tell the Commander in Chief the REAL truth while they have his ear, instead of speaking the truth while on their way out or already out -- REMEMBER CIA Director, George Tenet?
