The Japanese have noticed that the PLA is a force in politics, as well:
In its annual defense white paper, Tokyo said some believe that relations between the People's Liberation Army (PLA) and the Communist Party leadership were "getting complex" and said this was a matter of concern.
There is a possibility that the degree of military influence on foreign policy decisions has been changing, the paper said, without elaborating.
"This situation calls for attention as a risk management issue," it added.
The Japanese have reason to worry about who gets to order the PLA to war.
On top of the issue of determining what is rational for them rather than what makes sense for us, we have reason to worry about what crisis in East Asia might escalate to shooting.
