It took its name from Bob Dylan's lyric, "You don't need a weatherman to know which way the wind blows", from the song "Subterranean Homesick Blues" (1965). "You Don't Need a Weatherman to Know Which Way the Wind Blows" was the title of a position paper that they distributed at an SDS convention in Chicago on June 18, 1969. This founding document called for a "white fighting force" to be allied with the "Black Liberation Movement" and other radical movements[8] to achieve "the destruction of U.S. imperialism and achieve a classless world: world communism".[9]
