This thread makes no sense at all. China invading neighbours for land? Typical fan boy stuff. And as far as resource are concerned, you don't need to own a land to exploit its resources. Why are most resources today scattered across middle-east and Africa, but mined by US, Canadian, British, French, Russian, Chinese companies?
The Chinese are pretty patient in their plans. They'll not snatch the throne from the US in a night coup. Instead they'll wait it out, and the US knows it well. US navy's asia pivot is all about this. They want to provoke China in conflict while they have a more potent military. But soon US wouldn't be able to keep up, mostly because of its economy, and its navy will start to shrink in East-Asia. When that happens China will in my opinion try to take back Taiwan, and the US navy wouldn't dare to interfere. Its all about right timing. Thats what the US is fretting over.
I would paint the US-China relationship as of two athletes:
US is like an athlete running in the 1st position, losing its stamina. And watching the Chinese athlete in 2nd position gaining up to it. When the Chinese runner comes side by side, the US guy grabs the Chinese runner's shirt from his back to stumble him.
So the only chance the US has to keep its position is to engage China now, or it'll be too late. And thats why it is refocusing most its naval assets towards China now. Once the pacific command is beefed up, the next phase will be 'provocation'. US will try its best to engage China, even using false-flag tactics. But its all my opinion.
