Jai Hind fella, you ought to really understand and or at least live in America to understand the s..t you're talking about because your posts come across generic and lifted from someone else's myopic views about China.
The whole China as ww2 US analogy is a more rosy perspective that assumes there won't be war in Asia, but rather distant conflicts where China only plays a proxy role.
A less rosy perspective is that the situation between China and US is similar to the one between Japan and Qing China in the early 1900s.
China has spent 200 years being a relative backwater, but has now decisively modernized to being the leader in the region/world. Its industry and productivity surpasses all it's neighbors. Like Japan, China modernized into a hostile world, surrounded by stubborn tributaries and vassals of its historic rival.
On the other side, you have the whole US empire, which is not just the US mainland, but also Japan, Philippines, SK and possibly India. They outnumber China in population and resources but not in industry. Like the Qing China of old, the US empire is not a solid entity but a loose coalition of "warlords". And similarly they embarked on a mission of modernization through the tech and trade war, but this modernization hasn't succeeded in bringing major industrial improvements.
There are differences because China is not a warlike society. But nevertheless maybe China will not have a choice, because what else is China to do if the tributaries of US remain stubborn and obstruct Chinese growth at every turn? China cannot suffer vassal states like Philippines brushing up to it all the time.
Also while US industrial capability today may mocked by many, we do not know how it will look 50 years later. What if huge US allies such as India can modernize? What if increased TFR in US gives them more disposable workforce compared to China's future lessened population?
If the whole enormously populated US empire united and modernize just a little bit under an effective government, they may become stronger than China.
So under that paradigm, China should mobilize its whole society and strike first, or at least strike the moment it realizes US will begin effective modernization. Only by partitioning US empire can China's long term security be guaranteed.
