If your trying to establish some comparison with nowadays debt crisis in countries, all i can say as an economic student is that this is all miss-information, what really matters is the countries internal economic growth, wealth and job creation and self production capability to increase self production vs need for imports.
The soverign debt problem is no problem at all, the powerfull world economies just found a way to finance themselves trough interest payed by some european nations, its what i call the "reversed Marshall Plan" and it will only increase the difference between rich and poor countries.
