EU and IMF deal on Greece still elusive
According to an EU source cited by Bloomberg, the EU and IMF disagree on the sustainability of Greek debt
Let me help out.
It's not sustainable, it will never be sustainable. Even if it appears to be sustainable, your forecasts are too optimistic. Even if your forecasts are pessimistic, Greece will find a way (possibly with the help of Goldman Sachs) to make the debt unsustainable.
Don't lend money to the Greek government.
