And now not only were these circumstances rare, but they were also inherently liminal. Technological and economic edges fade rapidly, especially in light of major population level differences. I see no reason to think China imagines they could or even wants to be anything like the US was 30 years ago. The world is returning to its more natural multipolar state, as it's more or less always been.
It’s by no means a given that a more even distribution of power leads to war or China ‘replacing the US’ as the only one. But an attitude where everyone thinks so, ironically, might.
The fact that you might be programmed to hate/dislike/fear China despite, I'm guessing having never been to China, is proof that America also programs you, just in another way.
Hint: Mostly through media.
Change any of those things in a significant way and I’m sure I would be a different person now. I love the idea that I am an autonomous agent of my own that exists self evidently outside of those bounds, I just don’t think it’s true.
China wants to replace the US and the west as the global power. This will lead to upheaval and likely a war. When that finally comes to pass it behooves the west and the US to protect itself from anything that could undermine its own protection. In order to win a war you need hearts and minds. Not a populace that is being programmed to think despotic neo-communist-capitalist-when-it-suits-them rulers in China are somehow paper tigers.
Let’s compromise here: they are adversaries now but I think they are preparing to become enemies in every sense of the word. If they invade Taiwan, shed blood in the conflict over the breached rusting ship in the Phillipines, continue supporting Putin in his illegal attempt to annex Ukraine then yes they will eventually become enemies.
