@Herr:
The Soviet Union indeed intended to spread communism all around the world, but whether that would necessarily have implied a military invasion of central Europe in the 1940’s, is not certain. Their approach varied quite a bit, from inciting revolutions of the “working class” in other countries, to promoting wars between “bourgeois” powers, to actual war.
Also, if I remember correctly, Lenin’s death was followed by a power struggle in the USSR between the Trotsky faction, which wanted to pursue an agenda of internationalist communism, and the Stalin faction, which wanted to focus on communism at home (or whatever the phrase was). The Trotsky faction lost, with Trotsky himself eventually going into exile and ultimately being assassinated.
