After a devastating war between the United States and the Soviet Union mankind has taken refuge beneath Earth�s surface. But the war continues above ground, with robots called �leadys� fighting on our behalf�or so the humans think. �The Defenders� was later expanded into a full-length novel entitled The Penultimate Truth, published in 1964.
