We were very excited and we brought speakers in – then it so happened that there was a marine recruiter in the center of campus and one of our brothers, one SDS person put up a sign with a quote from the Nuremberg trial and an arrow point at the marine recruiter, saying, "This man is a war criminal." My younger brother and I, he was freshman and I was a sophomore, got caught up in the debates that were swirling around the center of campus and the young Trotskyists had put out a fact sheet on Vietnam that was phenomenal.

You cannot live a political life, you cannot live a moral life if you're not willing to open your eyes and see the world more clearly. See some of the injustice that's going on. Try to make yourself aware of what's happening in the world. And when you are aware, you have a responsibility to act.

I think that you're smarter than we were, but we had two things: one is, in our naïveté we believed we could change the world. And number two, we believed that another world was possible. And once that belief took hold of some critical mass, a tiny minority nonetheless, but a critical mass of people, then the world did change.

It felt to me like I was living my life in a way that didn't make mockery of my values. That's what I intended to do. So, that became a very radicalizing proposition for me.

The massive anti-war movement, which I was a part of and which was a major part of my life, never stopped the war in Vietnam.

I voted for Obama and I was delighted that he's been elected.

In terms of my own behavior and activity, the funny thing about regrets and saying "I'm sorry," is that there's so much I would do differently and want to do differently moving forward.
