When the Western Jin Dynasty decided to attack Wu, why did Jia Chong, Xun Yu and others strongly oppose it?

From the fifth year of Xianning (279) to the sixth year of Xianning (280), Sima Yan, the emperor of the Western Jin Dynasty, perished in Soochow, which was unified in three parts. Interestingly, the biggest obstacle to Sima Yan's destruction of Dongwu was not Dongwu's resistance, but the opposition of Western Jin heroes headed by Jia Chong and Xun Yu.

After replacing Wei, he was ready to attack Wu, but he was strongly opposed by the pack. Jia Chong wrote back to Sima Yan when Dongwu perished, demanding the immediate withdrawal of Wu Dajun, which made a big joke. Then why did the Founding Fathers of the Western Jin Dynasty, represented by Jia Chong and Xun Yu, strongly oppose attacking Wu?

First of all, Soochow was not the only military threat in the Western Jin Dynasty at that time, and many ethnic minority regimes around it were also threatening the Western Jin Dynasty, showing signs of "five riots". Jia Chong, Xun Yu and others think that the unstable situation in the rear is not suitable for cutting Wu, but this is only the secondary reason for their opposition to cutting Wu.

Secondly, in the decades before the Western Jin Dynasty wiped out Wu, Cao Wei and the Western Jin Dynasty all failed in their many attacks on Dongwu, including the fiasco in the battle between Battle of Red Cliffs and Dongxing. Therefore, Jia Chong, Xun Yu and others with poor military capabilities think that they can't perish, and cutting Wu is to die.

Finally, the Jiangshan of the Western Jin Dynasty was not shot down by Sima Shi, but usurped Cao Wei. Jia Chong and Xun Yu became the founding heroes not by the military, but by which side they stood and plotted with each other. Similar to Sima's throne, the heroes of Jia Chong and Xun Yu are also unstable.

Therefore, the heroes of the Western Jin Dynasty, represented by Jia Chong and Xun Yu, are very worried that the rise of real military and political ministers will harm their vested interests. When a large number of military ministers were most likely to appear, the Battle of Wu was destroyed. Jia Chong and Xun Yu, the founding heroes, naturally strongly opposed the felling of Wu.

Generally speaking, cutting Wu is a great threat to the interests of Jia Chong and Xun Yu, the founding heroes of the Western Jin Dynasty. Coupled with other factors, they are strongly opposed to cutting Wu. After the destruction, several heroes of the Western Jin Dynasty who destroyed Wu were excluded or even framed to varying degrees.
