He was in contact with Lionel Rogosin while the latter was filming his anti-war film "Good Times, Wonderful Times" in the 1960s. He became a hero to many of the youthful members of the New Left. In early 1963, in particular, Russell became increasingly vocal in his disapproval of the Vietnam War, and felt that the US government's policies there were near-genocidal. In 1963 he became the inaugural recipient of the Jerusalem Prize, an award for writers concerned with the freedom of the individual in society. In 1964 he was one of eleven world figures who issued an appeal to Israel and the Arab countries to accept an arms embargo and international supervision of nuclear plants and rocket weaponry. In October 1965 he tore up his Labour Party card because he suspected Harold Wilson's Labour government was going to send troops to support the United States in Vietnam.
