The U.S.A. and the Soviet Union seem destined to play a vital part in the future. They differ from each other almost as much as any two advanced countries can differ and even their faults lie in opposite directions. All the evils of a purely political democracy are evident in the U.S.A.; the evils of the lack of political democracy are present in the U.S.S.R. And yet they have much in common—a dynamic outlook and vast resources, a social fluidity, an absence of a medieval background, a faith in science and its applications, and widespread education and opportunities for the people.
