He might reduce corruption in the military. But after he’s done returning China to the Mao Era he will have utterly crap military gear. He could and probably will institute a reign of terror with secret police everywhere. This will result in a even worse level of military gear than he has now. And more demoralized troops. He will then have a crashed economy and no way to mount an invasion. Chances are good he’ll face a revolution if her tries.
China has made remarkable strides in upgrading their military.
They have stolen a lot of sophisticated military technology from anyone worth stealing from.
And they make a lot of the raw materials and components that the West uses in it’s military gear. Heck, a pretty substantial chunk of our military industrial base has been transplanted to China.
We underestimate China at our risk.
