And what does Round 2 look like?
Does it look like the decades long wars which pitted the British Monarchy against the new French Republic and then the Napoleonic Empire? But the biggest difference is that China looks more like a unified Europe and is secure on land. China does have a larger population and economy than the US, so could focus on building a larger Navy as well.
Or would it look like the transformation of Imperial Germany into a Nazi Germany some 20 years later, seeking vengeance for World War 1? The biggest difference is that the US economy was far larger than Imperial Germany or Nazi Germany. In comparison, with 20 years of peace, China could aspire to grow its economy to much larger than the US.
Remember that today, China is the clear overall leader in terms of Third Industrial Revolution technologies ie. solar, wind energy, nuclear energy, electric vehicles, batteries, 5G, Artificial intelligence. If China leads the ongoing Third Industrial Revolution, you would expect China to become a hi-tech and high-income country. And with a Chinese population 4x larger than the US, you could expect an economy 4x larger. That would support a much larger military than the US.
It just reinforces the point that the US is unlikely to *win* in any US-China war.
And whilst all this is going on, the chances of catastrophic and irreversible climate change increase significantly (ie. an increase of 5 degrees centigrade)
The discussion was about the victory conditions of the conflict and the outcomes of it, rather than how any subsequent successive potential conflict or competition decades post-conflict may look like.
That kind of long term post-conflict speculation is not even something we can begin to think about, so trying to make assertive arguments for how that should be factored into conditions of victory of the conflict at hand, is not reasonable at all.
