By 1969, Ellsberg began attending anti-war events while still remaining in his position at RAND. In April 1968, Ellsberg attended a Princeton University conference on "Revolution in a Changing World", where he met Gandhian peace activist Janaki Natarajan Tschannerl from India, who had a profound influence on him, and Eqbal Ahmed, a Pakistani fellow at the Adlai Stevenson Institute later to be indicted with Rev. Philip Berrigan for anti-war activism. Ellsberg particularly recalled Tschannerl saying "In my world, there are no enemies", and that "she gave me a vision, as a Gandhian, of a different way of living and resistance, of exercising power nonviolently."[16]
Ellsberg experienced an epiphany attending a War Resisters International conference at Haverford College in August 1969, listening to a talk given by Randy Kehler, a draft resister, who said he was "very excited" that he would soon be able to join his friends in prison.[17]
Decades later, Ellsberg described his reaction to hearing Kehler speak:
And he said this very calmly. I hadn't known that he was about to be sentenced for draft resistance. It hit me as a total surprise and shock, because I heard his words in the midst of actually feeling proud of my country listening to him. And then I heard he was going to prison. It wasn't what he said exactly that changed my worldview. It was the example he was setting with his life. How his words in general showed that he was a stellar American, and that he was going to jail as a very deliberate choice – because he thought it was the right thing to do. There was no question in my mind that my government was involved in an unjust war that was going to continue and get larger. Thousands of young men were dying each year. I left the auditorium and found a deserted men's room. I sat on the floor and cried for over an hour, just sobbing. The only time in my life I've reacted to something like that.[18]
Reflecting on Kehler's decision, Ellsberg added:
Randy Kehler never thought his going to prison would end the war. If I hadn't met Randy Kehler it wouldn't have occurred to me to copy [the Pentagon Papers]. His actions spoke to me as no mere words would have done. He put the right question in my mind at the right time.[19]
After leaving RAND, Ellsberg was employed as a senior research associate at the Massachusetts Institute of Technology's Center for International Studies from 1970 to 1972.[20][21]
In a 2002 memoir, Ellsberg wrote about the Vietnam War, stating that:
It was no more a "civil war" after 1955 or 1960 than it had been during the U.S.–supported French attempt at colonial reconquest. A war in which one side was entirely equipped and paid by a foreign power – which dictated the nature of the local regime in its own interest – was not a civil war. To say that we had "interfered" in what is "really a civil war," as most American academic writers and even liberal critics of the war do to this day, simply screened a more painful reality and was as much a myth as the earlier official one of "aggression from the North." In terms of the UN Charter and of our own avowed ideals, it was a war of foreign aggression, American aggression.[22]
