If China was to attack the USA...

1. Classically, it would attack at between 3 and 4am in the morning which is when humana are at their lowest ebb.
2.It would attack once it knew that a weak Rpesident had just been re-elected.
3. It would attack a weak ally of the US at the outbreak. If the US does nto respond then it could pocket that gain and see a key competitor in micro-electronics like Japan gone.
4. It would distract the US by dumping astronomic amounts of stocks, bonds and in particular stock and bond futures, undermining the US economy AND making it a fortune.

In particular, markets never crash inDecember because there are just too few people left in the market, not away on holiday, so if the markets are in free-fall it is because one super-big holder of US bonds and sock is selling flat out. (I wonder who thta could be?)
