Can you cite a source of this and perhaps go in to it a bit more?
Regardless, it makes for more interesting reality tv than catching up with the Khlardäshiäns[2].
So before Greece was too late, they were too early because there wasn't a peace treaty yet. There's no way for them to win.
In any case, Germany had massive amounts of debt forgiven, so them tightening the screws when someone else owes them money, is very hypocritical. Add to that that Germany is really rich and could easily handle a $100 bn or $300 bn loss, whereas Greece is in serious trouble, and that's partially because of Germany.
The reason Germany is so unforgiving, is that back in 2008, Merkel wanted to rescue the banks from their bad loans, and when the German voters questioned whether that was wise, she promised that the loans would be repaid. Forgiving the loans now would be breaking that promise. Merkel wanting to save the banks from their own foolish risks is part of the problem. Had they not lent money to Greece, Greece would have had to restructure much earlier. Instead, Greece was allowed to live on money they didn't have, and all of Europe knew and was fine with that. Until the crisis hit, and now Greece is the scapegoat for everybody's problems.
I'm not saying Greece is innocent here; they obviously aren't. But almost everybody carries some of the blame here, especially Merkel, and now they're sacrificing Greece to absolve themselves of their own mistakes.
This is a hairy topic, with Germany insisting that these matters were closed in the Two-plus-Four Treaty, and Greece wanting to be repaid for their post WWII magnanimity, in addition to this being viewed as the Greek government trying to weasel themselves out of systemic issues and necessary reform using dubious legal claims.
Germans, and younger Germans in particular may also view this as a "sins of our forefathers" issue, which also strikes a nerve, especially since the claim seems frivolous to many.
If Greece were devastated by a natural disaster and demanded aid citing their waving of reparations more than 70 years ago, this would be viewed in a different light, but the general perception in Germany is that they brought this issue upon themselves, even though the situation is likely considerably more complex than that.
Very very controversial, that's as much as I'll say.

Also, if a company borrowed money and couldn't repay it, they can declare bankruptcy and have their debt restructured. Greece needs to have their debt restructured. Most financial experts say it's irresponsible to expect them to pay it all back, but Germany took those debts from the banks (in order to protect the banks) when it was already clear Greece couldn't pay, and then used their political weight to enforce full repayment.
The way Germany treated Greece is disgraceful and foolish on several different levels, and it's extremely damaging to the EU.
