"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. 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). For the Janubombing of the United States Department of State building, they stated that it was "in response to the escalation in Vietnam".The Weathermen grew out of the Revolutionary Youth Movement (RYM) faction of SDS.

For the bombing of the Pentagon on May 19, 1972, they stated that it was "in retaliation for the U.S. Three members of the group were killed in the accidental Greenwich Village townhouse explosion but no civilians were killed in any of the terrorist attacks.įor the bombing of the United States Capitol on March 1, 1971, they issued a communiqué saying that it was "in protest of the U.S. Some attacks were preceded by evacuation warnings, along with threats identifying the particular matter that the attack was intended to protest. The group stated that the United States government had been exploiting other nations by waging war as a means of solidifying America as a greater nation. In 1970 the group issued a "Declaration of a State of War" against the United States government, under the name "Weather Underground Organization".The bombing campaign targeted government buildings, along with several banks. The "Days of Rage", their first public demonstration on October 8, 1969, was a riot in Chicago timed to coincide with the trial of the Chicago Seven. The Weather Underground was classified by the FBI as "domestic terrorist group." With revolutionary positions characterized by black power and opposition to the Vietnam War, the group conducted a campaign of bombings through the mid-1970s and took part in actions such as the jailbreak of Timothy Leary in 1970.

Their political goal, stated in print after 1974, was to create a revolutionary party to overthrow U.S. Weatherman organized in 1969 as a faction of Students for a Democratic Society (SDS) composed for the most part of the national office leadership of SDS and their supporters.

Originally called Weatherman, the group became known colloquially as the Weathermen. The Weather Underground Organization (WUO), commonly known as the Weather Underground, was a radical left militant organization active in the late 1960s and 1970s, founded on the Ann Arbor campus of the University of Michigan.
