The organization adopted a new strategy after the war called the "molecular theory" of revolution, where Soviet citizens were urged (via propaganda literature and radio messages) to create "molecular revolutionary groups" no larger than three people in size in order to minimize the risk of infiltration. These groups were to keep in contact with the NTS center which was located in Frankfurt, Germany. At a ripe moment, the center would coordinate the activity of the molecules and create a revolutionary army out of them.
