Earlier quoted context omitted.
What makes the BRI an over-extension? How does it compare to the economic and military extension of the other super-power?
Not only do you have BRI but massive internment camps, massively expensive surveillance systems, massive number of police officers, expensive great firewall. Look China is at war. It's just at war internally and spending a lot of money on it. This internal war is likely more expensive then USA's many foriegn misadventures. Thus China needs to go to Hong Kong to use their money and connections. China has no choice.
Unsubstantiated conjecture. Only time and history will tell. It is quite likely that the long-term strategic benefits to China will be (to use your favourite word) massive. Witness the outcomes of the Marshall Plan for a direct historical analogue.
> massive internment camps
A mainstream media falsehood one would be wise not to parrot: https://off-guardian.org/2018/09/19/no-the-un-did-not-report...
> massively expensive surveillance systems
Given the Snowden revelations it is clear that China is unexceptional in this regard. Also, source for "massively expensive". Define "massively".
> massive number of police officers
Source for this claim? Define "massive". But even if they were to have a large police force, what would be inherently wrong with that? Isn't law and order a good thing? Or are you assuming that just because they're employed by the Chinese State that no police officer can be good? That would be painting with rather a large brush, wouldn't it?
> expensive great firewall
Source that the Great Firewall is expensive. Is it more expensive than the enormous NSA Utah Data Center and the innumerable data pipes which feed it? https://en.wikipedia.org/wiki/Utah_Data_Center
> Look China is at war. It's just at war internally and spending a lot of money on it.
By China, you mean the Communist Party of China I presume. Because otherwise you'd be talking about a civil war which is clearly not the case. It's true that the CPC brooks very little outright dissent, and it's true that the CPC's regime is virtually totalitarian when it comes to political ideology and expression. But to say that the CPC is at war with its own population is bonkers. It's well documented that there are tens of thousands of demonstrations a year so it would be incorrect to claim that the regime is 100% totalitarian (like N. Korea, for instance) https://en.wikipedia.org/wiki/Protest_and_dissent_in_China
> This internal war is likely more expensive then USA's many foriegn misadventures.
Unsubstantiated balderdash. We can see from the USA's ever-increasing deficit mountain owing to the enormous and ever-increasing Defense budget that there is no Earthly way this claim of yours is true. The USA's many foreign misadventures (a lovely way of articulating something that has destroyed millions of lives and caused untold suffering) are collectively easily more expensive than the CPC's ongoing dissident surveillance, suppression and security apparatus.
“The bill, which passed 85-10 in a massive show of bipartisan support, represents a considerable boost in defense spending across the board – roughly $82 billion just for next year.
The annual increase by itself is bigger than the annual defense budget of Russia ($61 billion) and the two-year jump of over $165 billion eclipses the entire defense budget of China ($150 billion).” https://www.rollingstone.com/politics/politics-news/can-you-...

Given the incorrect premises undoubtedly your conclusion is incorrect.
