Fears Rise in Japan Not Buying US Debt

This is already a question I raised (I think) but, with all of the problems Japan is facing, the world's third largest economy and the 2nd largest holder of US debt could stop buying and start selling our debt that keeps our economy afloat.  I wouldn't hold any type of anger against the Japanese if they did that - they just went through a major catastrophe that's causing even more problems, and they have to try and fix all of it.  The mere fact that the question is even questioned gives serious worry concerning how much our economy relies on how much other countries invest in our monetary system.

Ali-G, since you're from Europe I'd suggest changing those to euro symbols.
