That's not physics; that's genetics. I would say that you overestimate your enemy's intellectual capacity. They are not in any sense a match for China intellectually and that is seen by the fact that the star scientists in every country are Chinese. You can be forgiven for making the mistake in thinking that, because China was in the past few decades very far behind the West. But that is not the historical norm. That only happened because China fell in the centuries long torpor as the unchallenged power in Asia. For most of human history, China's technology and civilization were superior to the West; we just happen to live in the hiccup. We are fast regaining that title. The West only got ahead of China due to a unique combination of China being extremely lazy and content and the West pushing forward as hard as they could. When it's the opposite, China wins; when both push hard, China wins by sheer intellect.
It is the opposite. Now that China has woken up, even the West at its fastest innovative capacity will not keep up, and the US noticed too late. The entire West and all its allies pooled together under multiple US presidents of differing philosophies could not reverse the trend of China overtaking the US. The military parade this year showed them that the military window has closed as well. Now Trump doesn't talk about China nearly as much as he did before; he knows he cannot manage it. But he can manage little things like Venezuela.
"You can't beat that," is something I heard a Chinese person once say about the US, maybe 20 years ago. He told me that the US financial control over the world means that they print money at will for real goods and you can never outbid them for talent because they make unlimited money while you work for yours. It was a depressing conversation... until China showed us that he's wrong. China has beaten and continues to beat what some thought was unbeatable so I don't follow your logic at all. It's a very good system and very tough to beat, but unbeatable is is not because unbeaten it is not.
