I don't think going back to dark-ages warfare would benefit anyone. In those days it was entire nations against other entire nations. Charge in and slaughter the men, women, and children indiscriminately. Albeit it was a lot easier to win that way, Iraq could have been long over with such an atrocious method. But the point of modern warfare technology is to minimalize the loss of life, by reducing your own troop casualties, by attacking with more precision, and by not charging into towns and slaughtering the populace. I can undoubtedly say that the conduct of war a thousand years ago was MUCH more brutal and unforgiving. Perhapse even though we still misuse military, we're on the right track; the track to turn warfare into a necessary evil that's carried out as efficiently as possible, with less innocent casualties (at least by intention).
