what you said is basically Taiwan's propaganda, and a very old one. it's still popular among some kmt supporters
the reason of why this is not true is because this concept is based on the logic kmt is still think Chinese civil way is only between CCP and kmt, and more importantly they still have the legal right to claim the mainland.
based on this acknowledgement, CCP is illegal controlling China at the moment, that's why pla is still remain a party military not a national army.
this unfortunately is not true, as the fact today, ccp and Chinese government are essentially one and united, almost all the major roles, from the top to bottum, are taken by the CCP members. also since they don't need to elect, thus there is no need seperate things like PLA from the nation Army. and most importantly attacking CCP is almost equal to attack China in most of time.
i believe what I said is plain and simple, and acknowledged by most people here, but still certain member like you like to spread this propaganda instead of discussing in an unbiased manner, that's I will call it off topic.
