Who owns the US?

'... While most of the country's $14 trillion debt is held by private banks in the U.S., the Treasury Department and the Federal Reserve Board estimate that, as of December, about $4.4 trillion of it was held by foreign governments that purchase our treasury securities much as an investor buys shares in a company and comes to own his or her little chunk of the organization.

Comment: Firstly, note that a large part of the UK position is actually money from other places and of dubious origin. You may well include Gadhafi or Mubarak as creditors along with other criminals and other dictators, which, secondly, is also the case with the Caribbean holders. Thirdly, to get the full sway that China holds, Hong Kong should be added to mainland China. Finally, one should mention that we have entered a phase where the debt accumulates in an exponential way on its own because of the interest effect.
