Going back a couple of years, the Vietnam War was the major factor in causing the creation of the Libertarian Caucus in Young Americans for Freedom at the 1969 National Convention. Legalizing marijuana was the other important issue we had with the YAF conservatives.
I was working for SIL when Dave Nolan started the Committee to Organize a Libertarian Party, in protest over Nixonâ€™s imposition of Wage & Price Controls. In his initial draft platform for the LP, Nolan called for withdrawal from Vietnam.
Unfortunately, Myrna Culbreath denounced the idea of surrending in Vietnam, and urged more bombing. She basically filibustered until the delegates deleted any reference to Vietnam in the platform. She then dropped out of the LP altogether.
During the 1972 campaign, John Hospers would occasionally mention the LPâ€™s opposition to the war, but it was not until the 1973 convention that a firm commitment to non-interventionist foreign policy made it into the platform.
Dana Rohrabacher was anti-war, and went with me to several anti-war protests. He even went to the big antiwar protest in San Francisco in October 1969.
Of course he was draft-age at the time.
