Stalin's "Socialism in one country" (which was in fact Lenin's socialism in one country) was never at odds with the goal of world revolution.
Stalin:
"Mr. Campbell still further stretches the truth when he puts such words into the mouth of Stalin as that "under Trotsky there had been an attempt to spread communism throughout the world; that this was the primary cause of the break between hirnself [i.e., Stalin] and Trotsky; that Trotsky believed in universal communism, while he [Stalin] worked to confine his efforts to his own country." Only people who have deserted to the camp of the Kautskys and the Welses can believe such stuff and nonsense, in which the facts are turned upside-down."

Anyway, from what I've seen most Stalinists that are real MLs (and not nationalists or sectarian role-player types) are ready to shut up about Trotsky's misdeeds and talk over the matters at hand, if only the Trotskyists could shut up about Stalin's supposed "betrayal of the revolution". But the Trotskyists are unable to get over their historical issues and repetitively demand the Stalinists to recant and repent, which reignites the holywar every time, which by itself, quite ironically, reaffirms the Stalinists' conviction that Trotskyism is nothing but the no. 1 way to wreck the communist movement.
