What were the social and cultural effects of the Vietnam War?

Much of the music from the 1960's was influenced by the Vietnam War. The dialogue will often have traces of Vietnam in them. Examples such as Scott McKenzies "If your going to San Francisco..." will mention the flower children, part of the hippy culture which fanned the anti-war movement; Sonny and Cher's "how many times must a cannon ball fly..."; Creedence Clearwater Rivival's, "...Run through the jungle, there's the land WE SMOKE!"; Country Joe and the Fish, "...well it's 1,2,3, what are we fighting for, don't ask me, I don't give a...next stop is Vietnam"; Crosby Stills & Nash, "Tin soldiers and Nixon's bombing, four dead in Ohio..." The music of the 1960's greatly influenced the culture in America.
