This communication from the Weather Underground was published on Sept 15, 1970 and explains how they helped political prisoner Dr. Timothy Leary escape.
The Weather Underground was a radical left militant faction of the Student Group Students for a Democratic Society. This position paper was distributed at an SDS convention in Chicago on June 18, 1969.
The contradiction between the revolutionary peoples of Asia, Africa and Latin America and the imperialists headed by the United States is the principal contradiction in the contemporary world. The development of this contradiction is promoting the struggle of the people of the whole world against US imperialism and its lackeys.
The accidental explosion of a Greenwich Village townhouse during a bomb-making session in 1970 left the Weather Underground– a radical left organization formed in 1969– distraught. In an attempt to reunify under their original goals at the time of formation, the group published a book, Prairie Fire: The Politics of Revolutionary Anti-imperialism. The book was intended to make a plan for organizing not just within the WU, but also with other radical left groups, and share ideologies, tactics, and lessons, all under the umbrella of anti-imperialism.
