The Revolutionary Communist Party, USA has taken on the responsibility to lead revolution in the U.S., the belly of the imperialist beast, as its principal share of the world revolution and the ultimate aim of communism. This Party is built on and takes as its foundation the new synthesis of communism that has been brought forward through the body of work and method and approach of Bob Avakian. Its members are united in their profound desire for a radically different and better world, and their understanding of the need for revolution to get to that world. They have dedicated themselves wholeheartedly to revolution, and on the basis of that they channel their individual abilities and passions to the cause and needs of this revolution.
