The Balkan wars were in 1912-1913. I can think of a few other significant things that happened in Europe since then. This crisis - it is really more of a tantrum than a crisis, since the Greeks know perfectly well they are on the hook for the money they spent on themselves - doesn't even register as a blip. It's not going to collapse the economy of the 400 million people within the EU/eurozone area, and even if it did, it still wouldn't reach the significance of 70 years of revolutions and communism and dictatorships and the freaking Holocaust and a couple of world wars, now would it?
This sort of wild-eyed panic mongering by people who take a bath on their real estate or stock purchase, and think that they are living through the worst crisis in the 7,000 years of recorded history, is beginning to wear thin. It's annoying even as deliberate hyperbole.
On top of this, the economic points made are stale and unconvincing. He talks about low interest rates being appropriate for Germany, but not for Greece. Well, guess what? You don't have to lend at low rates to Greek institutions. You can take a risk premium on top of the basic Euro central bank rates. People weren't doing that because they thought that Greece would catch up economically to the Euro average; it didn't, and the risk premiums went up. Hardly worth killing the Euro zone over this.
EDITED to add: he probably meant the wars in former Yugoslavia, rather than what's actually known as the Balkan wars. OK, but frankly, this is still crap, since clearly the creation of the Euro block itself and the unprecedented economic expansion in its new members is far more significant than a tantrum in 3% of the Eurozone. And the economic points are absolute garbage: yes, Argentina recovered, because it is a mining/exporting country and commodity prices skyrocketed. Not very relevant to Greece.
