The Weatherman group had long held that militancy was becoming more important than nonviolent forms of anti-war action, and that university campus-based demonstrations needed to be punctuated with more dramatic actions, which had the potential to interfere with the U.S. military and internal security apparatus. The belief was that these types of urban guerrilla actions would act as a catalyst for the coming revolution. Many international events indeed seemed to support the Weathermen's overall assertion that worldwide revolution was imminent, such as the tumultuous Cultural Revolution in China; the 1968 student revolts in France, Mexico City and elsewhere; the Prague Spring; the Northern Ireland Civil Rights Association; the emergence of the Tupamaros organization in Uruguay; the emergence of the Guinea-Bissauan Revolution and similar Marxist-led independence movements throughout Africa; and within the United States, the prominence of the Black Panther Party, together with a series of "ghetto rebellions" throughout poor black neighborhoods across the country.
