That's a pretty deep question, and you'll have to allow me a little bit of a sidebar here.
There are several issues in a counter-insurgency, and one of them is infiltration routes. Frankly, infiltration routes are not being addressed to the extent they could be at this point in time, because there aren't enough troops. That will be one of the principal focuses of the U.S. combat forces in southern Afghanistan--not the exclusive one, but one of the principal ones. So clearly that will contribute to the overall counter-insurgency strategy.
Will it change what the Afghan National Army does on the ground? I doubt it. They're the ones who are better suited to secure the population, because they understand the population much better than we could ever hope to.
Does that answer your question, sir?
