"Revolutionary Youth Movement" is to build a centralized organization of revolutionaries, a "Marxist–Leninist Party" supported by a mass revolutionary movement to support international liberation movements and "open another battlefield of the revolution." The theoretical basis of the Revolutionary Youth Movement was an insight that most of the American population, including both students and the supposed "middle class," comprised, due to their relationship to the instruments of production, the working class, thus the organizational basis of the SDS, which had begun in the elite colleges and had been extended to public institutions as the organization grew could be extended to youth as a whole including students, those serving in the military, and the unemployed. Students could be viewed as workers gaining skills prior to employment. This contrasted to the Progressive Labor view which viewed students and workers as being in separate categories which could ally, but should not jointly organize.

The lyrics had been quoted at the bottom of an influential essay in the SDS newspaper, New Left Notes. By using this title the Weathermen meant, partially, to appeal to the segment of U.S. youth inspired to action for social justice by Dylan's songs.

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
