This is correct as the Red Army personnel are trained in the morality of Marxist-Leninism, and understand their role to be one of ‘protection’ and ‘liberation’, and never one of pointless ‘aggression’ and ‘murder’. It is the Red Army that is tasked after the Revolution, to keep the workers safe. If civil society is to progressively develop through the application of science, then workers as citizens must be ‘free’ of the fear of arbitrary death and maiming from other citizens. Only the Red Army possesses the appropriate morality to carry out this task.
Part of the problem with interpreting Soviet history properly, is that nowadays there are Russian academics who accept the US Cold War disinformation as ‘fact’ and do not question it. These types of people are like ‘enemies within’, which teach false history and perpetuate anti-Soviet and anti-Russian lies.
