Vladimir Lenin -- the founder of the Soviet Union -- realized that of his two right-hand men, foreign affairs minister Leon Trotsky was the one best-suited to lead the country upon his death. But the sly, scheming Stalin had used his position as party secretary to build a power base that owed him big-time.
