It was only a matter of time before Xiang Yu claimed to be emperor, but he would not do it immediately, and if he did, he might not be able to do it, not the question of whether to kill Liu Bang at the Hongmen Banquet. Because although "claiming the emperor" is a historical trend, it also depends on the ability and talent of the individual. Obviously, on the surface, Xiang Yu has the above conditions, but he still lacks a little toughness. It's like using the same ingredients to make a pot of food, and some people are better than others.
According to the history books, Xiang Yu hated to be an emperor, and his philosophy of life was that "it is better to enjoy alone than to enjoy everyone", so he would enter the customs and burn Xianyang, destroy the old suppression of the Qin state, and then seal the princes and finish the matter. However, dividing the world was not as simple as Xiang Yu imagined, and when he returned to Pengcheng and had not yet passed the addiction of "returning to his hometown", the State of Qi began to be in turmoil, and then Liu Bang left Hanzhong to incite Peng Yue and other princes to start attacking the Western Chu regime. As a result, the violent Qin had just been eliminated, and the Chu-Han War was staged again.
So, if Liu Bang died, would the princes still rebel? Inevitably, for Xiang Yu, without Liu Bang, there was only one less prince who divided the land, but the princes would still fight for the sake of interests, rather than getting along harmoniously. Perhaps Xiang Yu would not have realized the drawbacks brought about by the various princes at first, but with the growth of age, the richness of his experience, and the face of the actual situation, he must have a clear understanding.
In this way, whether to unify the world to end the war, or to let the world chaos become a pot of porridge, or wait for the birth of the "next Liu Bang" to solve these problems, Xiang Yu must make a choice. And the only option is to unify the world and establish a centralized state, which is an answer given from the hundreds of years of strife in the Spring and Autumn Warring States. Qin Shi Huang could realize that Liu Bang knew how to follow suit, and as long as he gave Xiang Yu time, he believed that he still had this understanding.
But whether Xiang Yu could do it was a problem, because he firmly believed in force, far less than Liu Bang's superb political strategy, and how to solve the princes was a tricky problem. Throughout history, Liu Bang used the method of boiling frogs in warm water, that is, first comforting the princes, giving them fiefs, making them numb, and then eradicating them one by one. Most of Xiang Yu would use the autumn wind to sweep away the fallen leaves, planning to eliminate the princes and kings together, but as a result, he fell into a state of isolation and became the target of everyone. In this way, even if Xiang Yu is like an elephant, it is very likely to be bitten by a bunch of rats.
