This is hysteria and BS. The biggest problem we are going to have with China is that they are going to drive the price of oil up, now that more Chinese are driving cars.
I'm inclined to agree, a war would be very bad for China economically; I can't see them hazarding it. But nationalism can be a compelling motivation. This was impressed on me several years ago when I met a Chinese-Canadian woman in Minneapolis. She could not understand why China (the mainland) shouldn't have the right to control Taiwan, nor could she understand why the West had any business interfering in the matter.
Looks like the Chicken Littles have come out to play.
Have you priced any steel or concrete lately?
China is hurting us, bad. The prices of commodities is going through the roof, and there's no end in sight.
Think of how their soldiers would overwhelm us if they came on our shores.
And then laugh it off if you wish.
