Why would you choose that low moment in Patton's career to use in attempting to make your point?
Under the circumstances of the wars in Iraq (the Bushist Bungle!) and Afghanistan, winning depends not just on how many enemy casualties we inflict. If the people of those nations can not be won over, then the battles will be lost and the lives and treasure we are spending there will be wasted. Another great general, Stanley McChristal, understands that. This is not your father's or grandfather's or George Patton's war. This is a wholly different kind of engagement.
