Just shut the SnP out of business.. we don't need them. it is easiest and most feasible solution probably.
Seriously, I don't understand this stuff but I'm think SnP may have overreached. For one, if markets discount the downgrade which is likely in the intermediate to long term then SnP own credibility will be lower.
Short term it will create for volatile markets and maybe some once in a lifetime buying opportunities of stocks.
