Soviet Russia has been behaving internationally very much as a satisfied Power, avoiding all trouble, and trying to keep peace at all costs. This is the opposite of a revolutionary policy which would aim at fomenting revolution in other countries. It is a national policy of building up socialism in a single country and avoiding all complications outside. Necessarily, this results in compromises with imperialist and capitalist Powers. But the essential socialist basis of Soviet economy continues, and the success of this is itself the most powerful argument in favour of socialism.
