ABSTRACT
The tactical principles and various policies formulated by Chairman Mao reflect the objective laws in class struggle and give full play to spirit of proletariat and art of waging struggle in flexible way. They are always the powerful weapon of the proletariat for uniting the people and defeating the enemies. In order to isolate the diehard forces, Chairman Mao made a concrete analysis of and drew a careful distinction between the different social forces and political factions of the enemy camps and the middle-of-the-roaders. Applying the revolutionary dialectics of "one divides into two" in making a scientific distinction between the enemy camps, Chairman Mao most clearly distinguished between the primary enemy and the secondary enemy and between the temporary allies and the indirect allies. The tactical principles formulated by Chairman Mao for struggling against the enemy represent a dialectical unity of firm principles and great flexibility. The purpose of flexible tactics of struggle is to adhere to firm revolutionary principles.
