People who read the post I linked to yesterday may have noticed that the discussion continues, and the author of the explanation of the tactics of the insurgency goes on to suggest ways to beat the insurgency. These ideas are interesting. Notice in the first option the suggestion to abandon the Geneva Conventions - as if we haven't already done that. The second option is a pretty good idea, but it would take a larger commitment of troops than our military can handle at this point, not to mention the general public having absolutely no stomach for an increase of that magnitude.
It's also important to point out that these posts offer methods of beating the insurgency, which may or not be equivalent to winning the war. Bush won't tell us what we're fighting for, so I don't know for sure, but I think it's safe to say that defeating the insurgency would really only get us back to square one (or maybe square two) where we have a whole country and infrastructure to rebuild. Of course defeating the insurgency is a worthy goal, but it's important to keep in mind just how deep a hole we're trying to dig ourselves out of at this point.
