If the U.S. government purposely wanted to damage the global financial system, the best way that they could do that would be to default on U.S. debt obligations.  A U.S. debt default would cause stocks to crash, would cause bonds to crash, would cause interest rates to soar wildly out of control, would cause a massive credit crunch, and would cause a derivatives panic that would be absolutely unprecedented.  And that would just be for starters.  But don’t just take my word for it.  These are the things that top financial experts all over the planet are saying will happen if there is an extended U.S. debt default.
