I don't believe I misunderstood. You said the USSR abandoned the goal of overthrowing capitalism around the world in 1924. They (Stalin, in the 1930s, at least) didn't do that exactly. They just temporarily abandoned it as a direct goal based on their own direct intervention, knowing it wouldn't work. They wanted to achieve it firstly indirectly by creating the conditions for revolution in capitalist countries. They also knew that Russia needed to transform into an industrial power before it was possible to expand communism.

> "A third feature of Stalinism was the idea of “socialism in one country”—i.e., building up the industrial base and military might of the Soviet Union before exporting revolution abroad. To this end, Stalin rescinded the NEP, began the collectivization of Soviet agriculture, and embarked on a national program of rapid, forced industrialization.
> In foreign policy, socialism in one country meant putting the interests of the Soviet Union ahead of the interests of the international communist movement. After World War II, as Winston Churchill famously remarked, an Iron Curtain descended across Europe as Stalin installed communist regimes in Poland, Czechoslovakia, Yugoslavia, Hungary, Romania, Albania, and Soviet-occupied East Germany as a buffer zone against an invasion from western Europe.
> Beyond Europe, the Soviet Union supported anticolonial “wars of national liberation” in Asia, Africa, and Latin America and gave economic and military support to communist regimes in North Korea, North Vietnam, and Cuba."
