Now, is China doing something America has not done? Absolutely not. Is it crazy for a country to want to become more powerful? Absolutely not. Is it wrong for a country to do so? I would argue not, since their first responsibility should be to their people, and usually -- not always -- a more powerful country on the world stage is better for the people of that country.
I believe in a globalized world, I am not a nationalist, and think if the world could truly come together, it would obviously be better for all of mankind. However, I am also an American, and although I don't love everything about my country by any means, I am going to pick and favor my country over a foreign one when that country is clearly an adversary. Does that mean I want harm to come to China? No. Does that mean I wish ill-will of the Chinese people? No.
And for what it's worth, I don't think anyone is unbiased and believe it is unrealistic to expect people to be. I think biases are as fundamental (in good and bad ways) to being human as walking on two legs is. Biases are critical to how our brain/memory works -- we have something like 180+ known cognitive biases (https://en.wikipedia.org/wiki/List_of_cognitive_biases). I think the best thing we can do is recognize and acknowledge when we have bias, and factor that knowledge in to how we are thinking about a topic. For example, because of what I do for a living, if I see a positive story about the benefits of marijuana or crypto, I will initially be inclined to believe it may be true; the good ol' confirmation bias at work. But, I also usually try to stop myself, and think more critically of the information being presented, since I know that I am going to be inclined to have that bias towards the two topics. I feel as humans, that is the best we can do. Anyone who pretends to not be biased in any way whatsoever is lying. My father was a psychiatrist for 43 years, and I talked to him about this many times over the course of my life, and he agreed that he's never seen someone who did not have bias.
