China will be our bitches until they decide to finally put up a fight. If/when that day comes, I am supposing that they will eventually come out on top since they have the boots to put on the ground...if any of us are lucky enough to survive the event that is.
Oil is the primary concern for the US because of a legacy infrastructure. Access to the resources necessary for moving away from oil dependence are being secured by China and other nations while the US expends energy just to maintain itself.
Watch for 'surprise' advances in diverse energy generation technologies, and China's continuing moves on natural resource acquisitions - especially
partnerships.
The pattern has been one of low-level expansion and integration. There is no need for direct conflict, only a show of force to distract and demonstrate capability. As the west forcefully blusters about, China and others have civilly ingratiated themselves among the most resource-rich regions through business partnerships. In other words, China is not just China - it is also Angola, Australia, Brazil, Estonia, Kenya, Mongolia, Thailand, Uruguay etc... China's strength is highly present in its relationships, exactly where the US is weak.
Our analysis differs somewhat.
- I don't think the world has (relatively speaking) yet realized any significant supply problems and probably will not for some time particularly if the economies stay sluggish. There is, however, some political utility in making mountains out of the current mole hills...invented or real.
- I expect that the US and a few other Western societies are much less dependent on oil for 'legacy infrastructure' reasons than most. Particularly the large developing BRICs countries. In the most optimistic circumstances it takes a great deal of time and wealth make semi-significant infrastructure shifts, and would be much more challenging for countries fighting a rear-guard action just keeping their populations fed.
- I expect China to be run out of most of the other countries you mention as easily as they were run out of Libya and Iraq as needed. Absent some pretty significant shifts in power structures and modes of political and military operations, that is. China can buy any resource they want and their stake is effectively nullified when we install some new puppet to head things up.
Now as best I can tell, China's methods of assisting with civilian infrastructure projects and making themselves useful at various tiers of the trade economy is setting that nation up with a much more favorable rating amongst the general populations of the various third-world countries. This compared to our blatant support of some pretty awful despots when that seems like the path of least resistance (the common-case in most parts of the world...which, to be fair, a practice not unknown for China to partake in...) I do believe that this popular support will be one of China's aces in the hole in future times.
That last part is something of a point of agreement I guess.
It would not surprise me if China did not feel that the planets were aligned enough to make their move for some time. Perhaps not in my lifetime. My best hope is that there will come a point when the the West has something of an organic collapse in the West and China steps into their place with minimal fuss and loss of life.
