First, you must define what you call "war". The war mentioned here refers to the just war, and also refers to the following four types of wars: first, the war against aggression; The second is the war against oppression; The third is the war against separatism; The fourth is a preventive war approved by legal procedures against people or organizations with real threat of attack.
Second, at the same time, you must declare that the peace you are talking about is real peace, peace without any threat, and peace for people to live a dignified life. Peace here is by no means the so-called peace of the conquered people, but the greed and oppression of life.
Third, you must be clear that a just war can bring real peace; In addition, under certain conditions, only through this means of war can real peace be brought.
Fourth, when a country is faced with a war of aggression, only through the war of anti-aggression can it defeat the aggressors and bring real peace to the people. At that time, Japanese imperialism invaded China because of War of Resistance against Japanese Aggression. The China people who opposed the aggression drove Japanese imperialism out of China and won a peaceful life for the people of China. Imagine that if we blindly tolerate Japanese imperialism, it will only bring endless humiliation and aggression, and it will only bring endless war, and we will never have peace.
Fifth, when people are oppressed, they have the right to resist, and they have the right to use all means to resist, including violent means (that is, war). The purpose of this resistance is for peace and a dignified life for the people. When the oppressive forces are unwilling to give up the war, only by means of war can the people win their due rights and live a peaceful and peaceful life.
Sixth, when a country's separatist forces split the country, it is legal for the country to wage war against the separatist forces. Of course, the country should strive to achieve national reunification through peaceful means. However, when peaceful means are not enough to safeguard national unity, non-peaceful means, including war means, become the choice to achieve national unity. This kind of war against separatist activities is a just war. Only through this kind of war can we maintain the permanent unity of the country and bring lasting and real peace to the people.
Seventh, when evil forces threaten war, when reactionary forces threaten war in reality, people who are threatened by war can only prepare for war, use revolutionary hands to deal with counter-revolutionary hands, and prevent war to the maximum extent. Once the evil forces wage war or will wage war, the people threatened by war have the right to defend themselves and to stop the unjust war or destroy it by just means of war.
Eighth, historical experience has proved that for the sake of peace, dignity, sovereignty and reunification, war is always a means that cannot be abandoned. Under certain conditions, war is an effective means, even the only means, to achieve the above-mentioned peace goals. At that time, it was our unremitting struggle to resist U.S. aggression and aid Korea that dealt a heavy blow to U.S. imperialist aggression and won hard-won peace for the new people. In the 1960s, Mao Zedong once said: If you want to fight, you must fight hard, with a calm border and 30 years of peace. This is the dialectics of peace and war.
