How far is USA from a soverign bankruptcy

Now that the debt collector has nearly tasted blood in Iceland, Dubai, and Greece, how long it is going to come knocking at the door of some of the world most notoriusly spendthirft nations...e.g. USA where everyone was riding a boom right from unavailable plumber to Wall street salesmen and their political mask in Capitol.

And It is rich (pun intended) to know that a once industrially mighty nation has crossed the point of no return in debt management.

There are only one option left for government of these countries.....default or hyperinflation....
Given that governments are made up of people and people tend to choose the course of least resistence...we will have hyperinflation.
