lol, exactly how China can beat US in LAnd if the war were fought in Vietnam and Korea?
Both country aren't favourable in term of troop deployment, Vietnam have too much vegetation where it will implead tank and infantry deployment rate. Plus both are coastal country, which mean Navy support can offset this.
Let alone whether or not China were welcome to deploy troop in Vietnam and Korea in the first place, then you don't just fight the American, but also the local garrison
You sounded like only PLA are going to improve in warfighting capability in the next 10 to 20 years. US is just sitting around and sucking its thumb like an idiot lol.
In 10 to 20 years, US will fight another 2 to 3 war, and that gaining experience that way, just use this generation as an example, I know how to fight a war and win a war, can you?
Please, at least join the military, then come back to me what US dare to do and dare not to.
