Think about how the Mujaheddin gave the (technologically and numerically superior) Soviet army fits in Asscrackistan, or how the remnants of the Taliban continue to give the (technologically and numerically) superior forces of the US problems. We have been in A-stan for more than 10 years, and if we left tomorrow, it would revert to it's former status within months. Never discount the effectiveness of motivated guerrillas with moderately effective weapons. Technology and numbers only go so far, and in the case of the US, the numbers of armed citizens FAR outnumber the total number of members of the military. In addition, many in the military would decline to obey illegal orders attack US citizens on our own soil.
