Well, we can only hope that Iraq/Afghanistan are the outliers of the 21st century, and we limit our future pre-emptive strikes.
I think we are not looking enough into the Chinese concept of unrestricted war. From what I read, the last war game on economical war gave China winner with a long long advance... What about an insurgent use of economical aggressive war actions? Just like releasing thousands of fake banknotes? Or savage exchange market actions against key industries? From the testimony I heard, Taliban countered DDR with opium. The idea is good but the mean are wrong: opium is still a controlled resource. But they had a result.

I know that China is looking at asymmetric war now, but still… They often come with good (dangerous) ideas.

But yes, should be an interesting reading.
