Let's be honest, tax evasion is pretty much a national pastime in the US too -- the difference is that here the IRS will come after you if you cross the line.
The only way forwards I see is for the Germans to take over the collection of Greek taxes, and to control Greece's spending too, at least for a generation.
I think we'll also see them sell their half of Cyprus to Turkey too, for a few billion Euros, once the austerity starts to bite. And the Germans have their eye on a few of the Greek islands too.
The Republic of Cyprus is a sovereign state, it's not part of Greece.
"US Treasury Bonds downgraded because of the Deficit Cap row? OK, so the Americans can just sell their half of Canada to France."
This Cyprus diversion of yours was just wrong to the point of surrealism. Let it go.
Canada hasn't been turned into a warzone in recent history by France and the US arguing over who owns it.
To my knowledge, the U.S. has never encouraged Canadians to overthrow their government, nor do they use Canada as an excuse to justify an expensive cold war against, say, France.
