I see the 60s for the US as a 1950s baby boomer as a time of hope brought on by civil disobedience where people question their government and refuse to accept the values that they have been indoctrinated with from the public school systems. To me this is a good thing for the human race.
As an interesting aside, from watching the excellent Ken Burns documentary series on Vietnam:
First, the war was started by the government under false pretences by president JFK who "wanted to look strong" and despite intelligence saying they should get out (an intelligence officer, one of the first casualties wrote "the British and French are finished in Indo-China, and we should leave too"). Seriously, hundreds of thousands of people died because some womanizing asswipe thought a battle would win him election points. I'm glad he got his brains blown out - it should happen to more of them.
The protests for the war only started when the draft was expanded to include less-poor, university people. Prior to that they were all flag-waving and for it ... when it was sending the poor to fight and die.
The bottom line is - if you want to be a pacifist, you need to take more of an active, engaged and informed role in politics. Standing on the sidelines while things are set in motion and then refusing to get involved isn't good enough - you should have been involved earlier to prevent them if you genuinely care about life. Likewise, don't claim moral superiority for refusing to carry a gun or to kill when your blind following and tacit support of politicians beating the drums of war allows pointless wars to happen (just to stroke some grinning buffoon's ego).
Vietnam was no WWII. It was completely pointless and unnecessary. But not fighting in WWII wasn't an option (Switzerland just wasn't invaded 'yet', they certainly would have been at some point but were not strategically important)
