China announced the official end of its notorious "one child policy" less than 10 years ago, on Oct. 29, 2015. The policy was in effect for 35 years, having started in 1980.
Do the math, everyone younger than 45 serving the People's Liberation Army is an only child. The entire body of their actual combat forces is composed of only children, only sons.
In a culture like China's where sons are expected to care for aged parents, imagine how unpopular would be a war where every combat death creates a newly-childless couple facing old age with no caregiver. no living progeny.
It is probably no coincidence that the PLA is almost never deployed outside the country, and when it has been, they've started no wars. The last time the PLA went to war outside China and sustained severe casualties, was in Korea and hostilities there ended well before "one child" became policy.
It is just possible China has no intention of getting into a serious fight anywhere except in defense of its own territory, and "own territory" might exclude Taiwan, as it now seems to do in all but rhetoric.
China's CCP leaders have held the country together for something like 77 years. That's no small feat in a culture with a several thousand year history of internal strife, regional warlords, civil wars, and foreign intervention.
Perhaps China can, in the current parlance, "take the win" and let the rest of us do likewise? I suggest this as one of several possible paths the future may allow, rather than as a prediction.
