Not to be rude, mate, but it sounds like you're somewhat of a war-monger, either encouraging armed conflict or preparing for one that will not soon happen.
I don't know about anyone else, here, but I am not one for war. The heightened tension of complete and utter nuclear self-annihilation during the Russian Cold War was enough.
The Chinese economy will not implode. It's not possible. 'Why?' Because, instead of producing-- for decades-- missiles, polymer firearms, and $150'000'000 military aircraft like the United States of America, they've produced cookware, rugs, clothing, furniture, tractors, raw materials, and food for Pakistan, India, Russia, Afghanistan, Kazakhstan, Japan, the Koreas, Thailand, Malaysia, Australia, Brazil, and countless others. Including yourself.
To wish for a Chinese demise is to wish for your own.
And, let's say, hypothetically, that China wanted to engage in armed conflict with a belligerent such as the USA. Who do you think the rest of the world is going to stand behind? A nation who exports the products of impossibly expensive defence contractors, or a nation who exports affordable consumer goods necessary for survival? It doesn't matter how intimidating-- whether real or fictional-- the Americans can present themselves, they cannot support an entire planet like China has for the last 25+ years.
And such a war will be short-lived because the USA does not have the political power to endure it, which is fueled by crude oil reserves, because they have none. China is the world's most powerful buyer of energy, by far. Heck, your biggest crude oil import is from Canada,
which makes up 23.73% of all the petroleum you have. Saudi Arabia is far, far,
FAR more inclined to sell crude oil to China than to the United States of America because of the Chinese trade surplus from decades of consumer export, as well as a wealth of natural resources, and, on top of which, being the world's leading producer of aluminium and other industrial alloys.
You didn't think that American high-tech weapons and military vehicles were made of American alloys, did you? China sold you the materials.
To label the Chinese as Adolf Hitler or Joseph Stalin is a generalisation. Being a successful and intelligently industrialising foreign nation does not mean being a political enemy.
By the way, Audi are garbage. They've been nothing but garbage since the '90s by their absolute mechanical merits. Same goes with their Volkswagen parent company.
