From ancient times to the present, if a country wants to wage war against another country, it must always find a high-sounding reason, which is what we often say. Most wars in the history of world wars are unjust wars, and the fundamental purpose of countries that started wars is to invade each other, so they find various reasons, and there are some wonderful reasons. In fact, whether the reason for launching a war is reasonable or not has no influence on the outcome of the war. If you want to win the war, it depends on whose fist is harder.

During the Spring and Autumn Period in China, in order to dominate the world, Qi Huangong led a large group of servant countries to attack the southern Chu State. Qu Wan, a minister sent by the State of Chu, asked Qi Huangong, "What's wrong with our State of Chu? Qi Huangong said: You Chu should pay tribute to the Zhou Dynasty, but you never pay tribute, so I will punish you on behalf of the Zhou royal family. Qu Wan replied: We didn't attack Bao Mao. This is really our fault. We will pay tribute according to the regulations in the future. Qi Huangong's original intention was to wage war. If he paid tribute, Qi Huangong's reason for waging war would be untenable.

So Qi Huangong invented another reason. Qi Huangong said: More than 300 years ago, Zhao Haoqi of the Zhou Dynasty led an army south and fell into the Han River and drowned. You Chu should be responsible. Qu Wan turned against Qi Huangong on the spot when he heard this. Qu Wan said that you should settle accounts with Hanshui about King Zhao of Zhou! If we want to fight, we are not afraid of you. At that time, Chu was a big country in the south, and Qi Huangong was not completely sure of winning. In addition, the reason why he went to Chu was untenable, so Qi Huangong, who was finally indefensible, had to withdraw his troops from Chu.

Chu launched a war against the vassal States, and also found reasons to make people laugh and cry. Sui was a vassal state named Ji in the Spring and Autumn Period, which helped Chu resist foreign invasion many times. However, in the Spring and Autumn Period when the rites and music collapsed, the State of Chu did not remember the gratitude of Sui, but sent troops to attack Sui. The emissary sent by this country said to Chu: We are not wrong. Why should we be beaten? As a result, the general of the State of Chu said: Our State of Chu is a barbarian, and it never makes sense. We don't need any reason to hit you. Hearing this sentence, the vassal States could only surrender obediently and were finally destroyed by the State of Chu.

In the early years of the Han Dynasty, Ying Bu, king of Huainan, launched a rebellion against Liu Bang. Liu Bang led an army into Ying Bu, and the two men talked before the battle. Liu said to Ying Bu, I am very kind to you. Why rebel? Ying Bu's answer is honest: Of course I want to be an emperor! Such a frank and honest reason is really ridiculous. After the Han dynasty, people's literary literacy improved, and there were very few wonderful reasons to participate in the war. When people start a war, they will weave dozens or even dozens of charges for each other, and then announce an accusation against thieves. These essays are all written by great writers, and their writing style and truth have merits.

There are also many wonderful reasons for going to war in the history of foreign wars. For example, in the12nd century, French King Louis VII cut off his beard, which was rejected by his wife. Louis VII's wife remarried to King Henry of England because of the beard problem, and encouraged Henry to wage war against her ex-husband. The cause of the war was that Louis VII cut off his beard, his ex-wife demanded a divorce and demanded a dowry, and Louis VII refused to return the dowry.
