What losses did Stalin cause to the Soviet Union?

The direct loss is the loss of Soviet lives: according to the secret police files, Stalin himself signed and executed 68 1692 people between 1937 and 1938. The total number of victims is still unknown; In the process of ethnic cleansing and immigration, ethnic minorities also suffered numerous casualties. It is also unimaginable that a large number of people died and caused economic losses.

What is more terrible than the loss of life is the loss of morality: during the purge, the security organs abused illegal torture and espionage, and everyone feared for himself, and false accusations and false confessions prevailed, and his personality was distorted; The suppression of the Orthodox Church led to the collapse of Russia's original moral system.

Loss of science and culture: many cultural figures who dared to tell the truth were killed and put into prison, which made Soviet literature endless; The essence of all fields of society has been destroyed, and even science has to be used by politics.

The cleaning of the army led to a significant decline in combat effectiveness, which made the Soviet army retreat under the attack of the German army at the beginning of the war, causing huge indirect losses to the whole country.
