Soviet technology would also be more advanced. It's true. If Stalin would not kill so many of his own people, the USSR would still stand today. It was the greatest Empire that ever stood and its collapse was what shook the century.

Russia/CCCP posses superior simplicity and the greatest environment of people. Their projects are simple yet effective and at low cost which makes their weapons the best. But Stalin's reign was terrible...I would have worked on economical conditions instead and not execute 20 million Russians which included the best scientists, doctors, architects, etc in the USSR and those who would surely shorten the Second World War by maybe a year to my opinion.
