Ah well let's see the US consider military force against Libya. And no they do not consider the same for China.
A "practical arrangement". If he enemy seem to have lost, get him. Otherwise do everything to please them. China has killed 25 years ago.
Not doing business with China is not an option any more. Because the USA have "outsourced" everything they need to have an own sound producing industry.
All the modern IT stuff it made in China, maybe Taiwan (but pst don't say that loud or BB China will get very upset). Yes there is Intel but hardly any stuff else needed for building computers are "outsourced". Yes it's to maximize the profits of the managers. And if that fails, then Big Daddy is not "far" away. A few trillions here or there among "friends"....
