Here's another one:
In the event of war, China's "One Child" Policy would really screw the country up. In Chinese society, the eldest son is responsible for taking care of the parents intheir old age. If enough young men die (i.e. each family's "Little Emperor"), how long do you think it would take for the older generation to take to the streets demanding the end of hostilities?
If I recall properly, China comitted over 1 million men against the UN in Korea and wound up losing 400,000. By my math, that's a 40% casualty rate. With the lethality of modern warfare, I think it would be possible to achieve 60% or greater casualties on any Chinese force with not much effort.
"I think it would be possible to achieve 60% or greater casualties on any Chinese force with not much effort."
Which would accomplish very little.
The Chinese took 40 million casualties in the 19th century Tai Ping rebellion. They wouldn't lose a moment's sleep over taking another 40 million tomorrow.
