History shows that wars are divided into two kinds-just and unjust. All wars that are progressive are just, and all wars that impede progress are unjust.
Mao ZedongRevolutions and revolutionary wars are inevitable in class society, and without them it is impossible to accomplish any leap in social development and to overthrow the reactionary ruling classes and therefore impossible for the people to win political power.
Mao ZedongEvery comrade must be brought to understand that the supreme test of the words and deeds of a Communist is whether they conform with the highest interests and enjoy the support of the overwhelming majority of the people.
Mao ZedongOur enemies are all those in league with imperialism - the warlords, the bureaucrats, the comprador class, the big Landlord class and the reactionary section of the intelligentsia attached to them. The leading force in our revolution is the industrial proletariat. Our closest friends are the entire semi-proletariat and petty bourgeoisie. As for the vacillating middle bourgeoisie, their right wing may become our enemy and their left wing may become our friend - but we must be constantly on our guard and not let them create confusion within our ranks.
