An example of war promoting human development

War is the continuation of politics, and mankind will eventually destroy it, so we should treat this problem dialectically. 1, the war is produced for the need of survival. The war in the animal world is a struggle between the weak and the strong, just to survive better, and so is the plant world. Some species have survived. 2. War can make human progress, but devastating war will make human retrogress. 3. A country will launch a war machine to attack and destroy another country. Hitler tried to exterminate Jews in World War II, but failed. However, the whole Jewish world suffered a profound disaster, and the pace of human progress slowed down at the expense of people's suffering. Some people laugh and make progress, while others cry and rise in retrogression. Imagine that if there were no wars for thousands of years, the world would be like now. No scientist or sociologist can give an answer, because it is impossible without war. Human ideology is different. Most people love peace, but only a few powerful people wage war. Looking at the war in our family, we can't compare it with the war between countries, the war between human beings and the war between people and animals. In war at home, only the losers have no winners, and the material gains have won, but the spirit has lost a lot. Some of them were criticized. This family will only decline. The same is true of civil war, which will only make a country suffer from internal troubles and foreign invasion. If it is for justice, the inevitability of war will be great. What would we think if we stood in outer space and watched the wars between countries on earth and the wars of mankind? It will be different. Small-scale wars such as local wars have little impact, but the occurrence of world wars will only set mankind back. If World War III breaks out, mankind will be punished. As for which era we will retreat to, it depends only on the intensity of the war. 7, so we can allow the existence of fighting, but we don't want war. 8. War makes mankind try its best to manufacture high-tech weapons, develop economy and strengthen national strength to subdue other countries, but it does not improve the possibility and intensity of future wars. 9. The progress of human society goes hand in hand with high risks and strong disasters, so the war is blocked.
