USTs should have been downgraded to F years ago. How can a country printing money to buy its own debt be anything but F? The same agencies that gave toxic mortgages based on half-milion dollar loans to drooling retards with no jobs or credit scores or down payments still have the US at AAA+. Internal emails from these agencies show they were hoping they would be retired before "this whole thing blows up".
When will people realize they have no credibility?
