The thing about Russia is they lie ALL THE TIME. The Khmer Rouge was actively conducting cross-border raids into Vietnam killing civilians. Ukraine was not attacking Russian territory. The Khmer Rouge killed 1.5-2 million Cambodians (roughly 25% of the population) in a well-documented genocide. Vietnam ended a genocide and withdrew most forces within a decade. Russia annexed territory and continues occupation.

The situations are not comparable at all.
