That is exactly what the muslims and Democrats want them to do.
This tells the muslims that if they keep fighting and killing American Servicemen/women long enough that the American public will grow tired and demand we stop fighting.
This is why it is important for us to stay in Iraq and Afganistan too for that matter.
Anyone who believes that if we only withdraw our troops from iraq and Afganistan that the muslims will stop fighting us and begin loving us is, at best delusional and at worse certifible insane.
