Now you may like the images of long-haired hippies running in the streets throwing tear gas canisters, but we didn't end the war. And that's what we set out to do. What was not ended by the anti-war movement was ended by the Vietnamese. That's our shame.

It's worth remembering that in 1965, something like 20% of Americans were against the war. Something like 70% were for the war. So, it wasn't a popular or an easy thing to do.

We're actually saying, here's a principle that I'd like to arc toward. That's a very different role in life. I didn't expect [Barack] Obama to go to the root of things. I didn't expect him to have a principled position on anything. I mean, just pay some moderate attention to the guy.

The Right said, [Barack Obama] is lying, he's a socialist who pals around with terrorists, he's a secret Muslim and blah blah blah. That was their line. The liberals all said, He's winking at me, I can feel him winking in my direction. He wasn't winking. He said exactly who he was and he's lived that out perfectly.

The idea that you live your life in phases - I've never bought that. I feel like I'm the same person who sat in at the draft board in 1965, I'm the same person who joined a fraternity, I'm the same person who got an MFA at Bennington, and I'm the same person who founded Weather Underground. My values are still intact.

That's in the nature of social change. So you can analyze what didn't work, but it's very hard to predict what will work.

I taught. I lectured at universities. I spoke to my students. I spoke in certain public forums. But what I didn't do was respond to microphones being thrust in my face and saying, what is your relationship with Obama and are you an unrepentant terrorist?
