Adjusting to Situations: Military versus Politicians

The more things change, the more they are the same. A recent ABC news poll of commanders on the ground in Iraq, the commanders echo Sun Tzu. Quoting Maj. Gen. Jeffery Hammond in Sadr City:
"Instead of any time-based approach to any decision for withdrawal, it's got to be conditions-based..."
How long have politicians been getting this idea wrong. 2,500 years ago, Sun Tzu said:
"The army's position is made more difficult by politicians in three different ways. Ignorant of the whole army’s inability to advance, they order an advance. Ignorant of the whole army’s inability to withdraw, they order a withdrawal..."
Some politicians might understand the irony of history repeating itself here if we put it in French, "Plus ça change, plus c'est la même chose."
