Jan. 21—Lyndon LaRouche’s political movement, led now by Schiller Institute founder Helga Zepp-LaRouche, has clearly become a critical force against economic collapse and world war, and toward an international architecture of development. On successive days last week, Helga Zepp-LaRouche led international conference calls of hundreds of mobilized people: first, of peace organizations, leading scholars and activists; then, of youth organizations and leaders from all over the world.
