This is a drum Col. Gentile beats often, and it's one I agree completely with. From the article:

Many army officers and Department of Defense thinkers seem to be able to think only about how to apply the perceived counterinsurgency lessons from Iraq to Afghanistan. A recent group of colonels asked the question "how should the army execute a surge in Afghanistan," instead of the more important questions of whether the army should use the surge counterinsurgency program there. A professor from a major Department of Defense university has gone so far as to call for the surge and its counterinsurgency techniques as the model for American strategy and policy throughout the entire Middle East.
He's right to be skeptical of what sounds like the simplistic importation of the Iraqi "surge" into Afghanistan. One of many problems is there seems to be no accepted definition of what exactly the surge in Iraq consisted of. Another serious problem are clarity issues at the policy level with respect to Afghanistan. Until those get worked out, it seems premature to declare that a surge in Afghanistan is either useful or necessary. And even if he's wrong, Col. Gentile is performing a valuable service by questioning and challenging the conventional wisdom.
