Actually, no. The US dominated the battlefields during the Vietnam War. As for the China-VN border war, the consensus was, and still is, that the PLA performed badly. Not just poorly, but badly. So you got gelded. Then you take a look at US and realize you had to reform. That means so far, whatever military scrotum you got left is just window dressing, pal. Testicular implants. Your PLA is corrupt and because of rank trading, its leadership is most likely filled with incompetents.
The best thing for the PLA to grow a pair of real balls again it to take down NKR, not taking on US. You ain't got the skills.
