I don't understand what you mean because American economy, military, and technology, have all improved in the last 30 years. They're not going backwards; they're just going forward slower than China.
That is kind of presumptuous to say that the world will always need to be run by the visions of a single country. I don't think China has the desire to interfere with things so far from itself, as over-extension and exhaustion has often been the downfall of many powers. China should aim to do what's important for itself to preserve and build its own nation and invest far less on global interference than the US. The world isn't a kindergarten for China or the US to run.
I think the fundamental reason why the West lacks STEM students is because they've grown too comfortable with their lead and everyone wants a comfortable life with a comfortable major. I can't foresee if China will also fall into this trap but one good thing is that Chinese families are so competitive with each other that even without other peer countries, they will still drive their kids to undertake the toughest academic challenges just to rub it in their neighbor's faces LOL
1) No, the US actually has ran backwards in many key metrics. Every institution has gotten worse since the 90s (basic education, infrastructure, financial regulations etc.) Even in scientific progress, the quality of journals like Science and Nature have deteriorated.
2) You're assuming that I'm presuming the world would/should be run by China's visions (that wasn't the point.) It would benefit my civilization a lot if China can help free the world from the Western world order so that we can get a chance to breathe without interference. We want time and space to figure out our problems in our own way.
3) There are more fundamental problems than the lack of STEM graduates. It's not just the lack of volume, it's the quality of the science and the corruption of the enterprise.
Ya. we got the Indians to withdraw, but what does that accomplish? Now Modi is jumping in glee to join the American cold war idea. Why don't we sit down and negotiate lasting truce with India and solve this problem once and for all?
You think Modi would be so eager to join the cold War if we didn't have a border dispute with them?
I'll disagree with you here. China trying to play nice with a country like India isn't going to work. Just ask all the countries who have tried to play nice with India. In fact, China has been trying to play nice with India since the beginning. It was always India which refused.
China definitely does need to be strong and show strength in protecting its rights and claims.
