• 1946: Bulgaria becomes a communist state with Soviet backing.
• 1948: Communist takeovers in Czechoslovakia and North Korea, establishment of East Germany, all with Soviet backing.
• 1949: Establishment of People's Republic of China; Hungary becomes communist, both with Soviet backing.
All of these events were aided by the USSR under Stalin's leadership. What the hell are you talking about, "he and the bureaucracy never had plans for world socialist revolution?"
