In terms of the Marxist theory the military conflict in Ukraine cannot be described as an imperialist war, as our comrades would argue. It is essentially a national liberation war of the people of Donbass. From Russia’s point of view it is a struggle against an external threat to national security and against Fascism.
It is no secret that the Donbass militia was unable to resist the many-thousand-strong foreign-armed Ukrainian armed forces. A defeat of the militias would have led to the annihilation of the Russian-speaking population, a large proportion of which are citizens of Russia. Under the Constitution of the RF, Russia took legitimate action to protect its citizens and ensure its national security because it could not have been done by other means.
