I remember Nixon's comment after leaving BW "We are all Keynesian now" (reference to the UK economist John Maynard Keynes). The separation of the dollar from a gold standard to a "production standard" meaning if your country can expand it's productive capabilities it can expand it's money supply.

If your country adopts a policy of exporting it's "productive capacity" to other countries you will be in deep trouble because your currency will end up being worthless!

If economic warfare is in play I would think a country such as China would have an objective in mind as opposed to just general financial chaos...so what is it??? maybe offer the US a debt swap for high tech military technology....access to patents without any royalties to be paid....advanced oil exploration technologies?? Just thinking out loud.
