Revolutions, like trees, must be judged by their fruit, Ignazio Silone wrote, China under the “Great Helmsman”, Kim Il Sung’s North Korea, Vietnam under “Uncle Ho”, Castro’s Cuba, Ethiopia under Mengistu, Angola under Neto, Afghanistan under Najibullah,...wherever Communism was established it quickly led to crime, terror and repression.
from The Black Book of Communism
There is a parallel here with the Russian government not releasing a Stalin film and the Deep State not releasing the texts and notes from the FBI and Justice department.
After Stalin's death in 1953, the Soviet Union dismantled the enormous system of terror and torture that he had created. But there has never been any Russian ban on former party functionaries, nor any external authority to dispense justice. Memorials to the Soviet victims are inadequate, and their families have received no significant compensation. This book's premise is that late Soviet and post-Soviet culture, haunted by its past, has produced a unique set of memorial practices. More than twenty years after the collapse of the Soviet Union, Russia remains "the land of the unburied": the events of the mid-twentieth century are still very much alive, and still contentious. Alexander Etkind shows how post-Soviet Russia has turned the painful process of mastering the past into an important part of its political present.
It's not holding Russia back, but all the places you mention as well.
