"Revisionism represents the interests of the labour aristocracy, and hence also the interests of the reactionary bourgeoisie. Revisionist trends run counter to the interests of the proletariat, of the masses of the people and of all oppressed people and nations. Ever since the days of Bernstein, Marxism-Leninism has been repeatedly assailed by revisionist and opportunist trends, each in its day stirring up a commotion. But history has confirmed that Marxism-Leninism represents the highest interests of the largest number of people and is invincible."
