China is now unified and within it reside about half the population of Asia. Like the Middle Kingdom before it ,it views itself and the dominant, central power of Asia. Yet like the Middle Kingdom it has its own inherent problems and meets a natural formidable resistance from other Asians when it overextends itself. Frankly now as then ,it will be up to the Asians themselves to work out a reasonable consensus. American involvement is foolish. It is not likely to be effective and historically does nothing for the security of the American people but inevitably creates long term bitter enemies and resentments.
All of what you say has some truth to it.
Yet all of it ignores the nature of the regime in China, how THAT also helps drive who China is TODAY and how it WILL ACT, and WHY - because it is a dictatorship. We have plenty of history, world history, of the behaviors of dictators BECAUSE they ate dictators and how we must act because of that.
Leaving ALL of that out of the equation, and understanding, about China, and pretending China is totally synonymous with some ancient situation will lead to either conflict we don’t need or capitulation in matters we should not capitulate.
It sums up as actually a RINO view that suggests just leave China be China and everything will be fine. It won’t.
