Yeah that was fraud. It wasn't a powerplay, just fraud.
And this tells us what about the relationship between the Eurozone countries?
Yeah, at this point I'm having trouble faulting the rest of the Eurozone for wanting to kick Greece out of the Euro and leave it to its fate. You commit fraud and cook the books to join the club, you shouldn't be surprised when it comes back to bite you in the ass later on. And if you keep Greece hanging around, it's just going to create headaches for the entire union every few years. It's much better to cut the cord and let it drop; once it's on the drachma it can take the required steps to become competitive again, since it will have control of its currency.
The real object lesson here, I think, is that monetary union without fiscal union is a bad idea, and the only way to really fix the underlying issue is to either have a federal European government or to dissolve the euro. After the fiascos that have taken place since 2008, I can't imagine the economic powerhouses of the Eurozone will have much appetite for the first option (since it would basically entail a perpetual bailout of Portugal, Spain, Romania, etc. with German, Dutch and French money, just as American federal spending bails out Alabama and West Virginia with Californian and east-coast tax money), and the union's underdogs will never vote for the second. The only real way to fix the Euro, I suspect, is to time-travel to 1999 and scrap the whole thing.
