Stalin had "socialism in one country," and yes, that has significant material and historical meaning, as opposed to being generic fluff. Because it was generally believed that building socialism required a number of successful workers' revolutions around the world.

Hence the strategy and policy of Stalin to build "socialism in one country." This is one of the major breaks between Stalin and Trotsky.
