Just war promotes social development and progress, while unjust war hinders social development and progress.
At the present stage of human civilization, permanent peace is impossible. As long as there is political struggle, there is the possibility of war, because war is the continuation and the highest form of political struggle. In reality, to achieve peace, it is necessary to strengthen combat readiness. "War preparation is the most effective way to grasp peace" (General Patton's famous saying). There is an old saying in China that only by preparing for war can we avoid war, and only by fighting can we make peace.
