What do experts say about Jiang Wei's true decline or false decline after the demise of Shu?

First, there will be a desire to revive the country, but the Lord has given up the country.

Shu Han was a country shot down by Liu Bei, and Liu Chan succeeded to the throne after Liu Bei's death. Liu Chan is suitable to be an emperor in times of peace and prosperity, but not in times of war. He is not as stupid as in romance novels, but this man has no talent for governing the country. First, Shu Han was put on the throne of power by Zhuge Liang, but Zhuge Liang was in power at that time. After all, the defeat of Yiling weakened Shu Han, and it was impossible to save Shu Han with Liu Chan's talent, so Zhuge Liang was in power at that time. After Zhuge Liang's death, national politics was in Jiang's hands, easy and silent.

Later, after these two people died, it was Jiang Wei's turn. Jiang Wei was originally from Cao Wei, and later took refuge. Jiang Wei has always wanted to realize Zhuge Liang's wish, revitalize Shu Han and succeed in the Northern Expedition. Liu Chan also delegated power to Jiang Wei at this time. After more than ten northern expeditions, Jiang Wei won many battles, but actually did not benefit. In the end, Shu Han was in danger, but Jiang Wei still didn't give up Shu Han. Jiang Wei is still fighting Zhong Hui at the front, while Liu Bei in the rear has surrendered to Cao Wei. Of course, Liu Chan can't be blamed. Liu Chan did what he had to do.

Second, Jiang Wei killed the three sages and only gave Shu Han a chance to live.

When Jiang Wei heard that Liu Chan had surrendered, he knew that the fate of Shu Han was exhausted, but he still didn't give up Shu Han. At that time, Cao Wei sent Zhong Hui and Wargo to destroy Shu because Wargo surrendered. Wargo felt that the first achievement was his own, and Zhong Hui felt that Jiang Wei was the main force, not that I was holding Jiang Wei. Can it succeed? So this is my own work. And Zhong Hui has always been an ambitious man. Jiang Wei saw Zhong Hui's ambition and his contradiction with Wargo.

Jiang Wei surrendered to Zhong Hui and bewitched Zhong Hui to revolt. With his own help, he is the next Liu Bei. In the end, Zhong Hui killed Wargo and seized the military power, but Zhong Hui's mutiny failed. Finally, Jiang Wei and Zhong Hui both died. For Jiang Wei, taking refuge in Zhong Hui is only a glimmer of hope for the revival of Shu Han. If Zhong Hui's mutiny succeeds, Shu Han still has a chance. If Zhong Hui fails, then Jiang Wei can be regarded as killing Wargo and Zhong Hui to avenge Shu Han. So Jiang Wei thought of Shu Han until he died.
