2Be, I don't think Vietnam was the cause of "[changing] the Military Code to allow for conscience objection to immoral commands."  I think the duty to disobey an illegal or immoral order long pre-dated Vietnam.  In fact, that was one of the main lessons of the Nuremburg trials.  That lesson applied even during the Vietnam years to Lt. William Calley, and long before that, the 1865 trial of Henry Wirz (The Andersonville Trial).   

Many of the those who have posted in response to me seem to have misunderstood what I say.  I certainly do not glorify war.  It is unspeakably abhorrent to me, even though (as Hobson points out) I have never been in combat.  But when innocent life is threatened by unjust aggressors, such as ISIS or Hitler or Mussolini or Stalin, the claim that Jesus was an absolute pacifist rings terribly false.  He wasn't.  And BTW, nothing that I've said in these exchanges has sought to justify our military actions in Vietnam, Central America, or even WWII Europe or Japan
