There were few events in American history which had a greater effect on American Society than the Vietnam War. For the first time, Americans abandoned their "America right or wrong" attitude, and looked at the war as an issue of morality and justice. The New Left and Counterculture were direct results of opposition to the war. The "peace" movement led to new forms of dress, new grooming styles (or lack thereof) and even the mass use of marijuana as a recreational drug. I'm not sure that I agree with the post above about the split between traditionalists and progressives. The war was fought primarily during the Administration of Lyndon B. Johnson, a Democrat, and concluded under Richard Nixon, a Republican. There was, however a sudden distrust in the military that resulted from misinformation given to the American people.
