What do you think the 60s counter-culture would be like without Vietnam to protest against? There probably still would be a rebellion against cold war era conformity but it might not have a political aspect to it, or if it did might just be a rebellion against curfew laws and the drinking age. I wonder if musically and fashion wise a more apolitical counter-culture might lead to more garage rock and leather related fashions and less flower power, maybe 60s garage rock evolves into an earlier incarnation of punk rock.
