Re: Ignorance of the issue
Said Eurozone implosion wouldn't have been the fault of Greece anyway, it's Germany you should be looking very hard at here.
Much was made at the time of the fiscal fudging that went on to allow Greece and Italy into the Euro, yet the German elephant in the room was quietly ignored as it's unfixable.
The problem is the German constitution and the Bundesbank (and we have the Allied Powers immediately postwar to thank for this). In a fit of rabid paranoia over the hyper-inflation of the Wiemar Republic and its results, the Bundesbank is fearsomely independent and has as an overriding goal the control of inflation. This can be Good Thing as it stops their version of the loony left tax 'n spending their way to bankruptcy (c.f. Gordon Brown, the current greek mob, etc).
The slight snag in this arrangement with the Euro is that if the European Central Bank were ever to set interest rates that conflicted with the requirements of the Bundesbank, it's hello constitutional crisis in DE and a rapid "gexit". Unfixable, as there ain't a cat in hell's chance of getting the required votes in Germany to change the setup. The net effect is that the allegedly independent CEB running the Euro for all countries is actually the Bundesbank's poodle.
When the PIIGS states started overheating (remember the "Celtic Tiger" and such?), everyone expected a hike in interest rates from the CEB of somewhere north of 0.5% to suppress this. At the same time the Bundesbank predicted a slight slowdown in the German economy, so what we actually got was a 0.5% cut in rates.
The effect on the Euro periphery was like pouring petrol on a fire and the rest is history.
 And had the side-effect of causing growth rather than recession in DE, compounding the fuckup, as the PIIGS blew loads of cheap credit on products by Porsche, Mercedes, Miele, etc ad nauseum.
