Our Constitution lays it down that citizens of the People’s Republic of China enjoy freedom of speech, the press, assembly, association, procession, … - Mao Zedong

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. We Communists oppose all unjust wars that impede progress, but we do not oppose progressive, just wars. Not only do we Communists not oppose just wars; we actively participate in them. As for unjust wars, World War I is an instance in which both sides fought for imperialist interests; therefore, the Communists of the whole world firmly opposed that war. The way to oppose a war of this kind is to do everything possible to prevent it before it breaks out and, once it breaks out, to oppose war with war, to oppose unjust war with just war, whenever possible.

The reactionaries attempt to quell the revolution by means of massacres. They feel that the greater the number of people killed, the smaller will be the revolution. However, it has turned out to be otherwise. Actually, the more people the reactionaries kill, the greater is the revolutionary strength and the larger the number of reactionaries who will perish. This is an irresistible principle. Hitler and Mussolini of foreign countries, the fascism of Japan and the Manchurian government and Pei-yang warlords of China have all proved this point. Though hundreds of thousands and millions of China's revolutionary people have been slaughtered, hundreds of thousands and millions more will rise and continue the revolution, and no one can subjugate them.

Over a long period we have developed this concept for the struggle against the enemy: strategically we should despise all our enemies, but tactically we should take them all seriously. This also means that we must despise the enemy with respect to the whole, but that we must take him seriously with respect to each and every concrete question. If we do not despise the enemy with respect to the whole, we shall be committing the error of opportunism. Marx and Engels were only two individuals, and yet in those early days they already declared that capitalism would be overthrown throughout the world. But in dealing with concrete problems and particular enemies we shall be committing the error of adventurism unless we take them seriously. In war, battles can only be fought one by one and the enemy forces can only be destroyed one by one. Factories can only be built one by one. The peasants can only plow the land plot by plot. The same is even true of eating a meal. Strategically, we take the eating of a meal lightly—we know we can finish it. But actually we eat it mouthful by mouthful. It is impossible to swallow an entire banquet in one gulp. This is known as a piecemeal solution. In military parlance, it is called wiping out the enemy forces one by one.
