Only way I can see them doing it is what Germany did after World War I.
!. Inflate away the debt therby making the US Dollar virtually worthless.
2. Raise Interest Rates to sell higher yield bonds
3. Revalue the price of Gold to $10,000 an ounce. Silver similarly.
4. Revert to at least a partial Gold/Silver Standard
Of course this would cause a great deal of pain for the avg American, but can't see any other way they could do it.
Of course, these are extreme measures, but somewhere down the road, it seems it's the only way out.
Unless they do get other countries to subsidize or pay off the debt for them like Nixon did when he took the US off the Gold Standard.
