Empty threats against Greece are part of brinkmanship from Germans.

Would the Germans really force Greece out of Euro?

Listening to the British media you would be mistaken on thinking the Euro was finished long ago.

But they are either wrong or mischievous or both. The British establishment has always poured scorn on European co-operation. And every time they have been wrong. The anglo-saxon markets are doing their best to destroy the Euro. But the continent thinks differently. Ultimately the politics of the Euro will beat the markets.

It is in no-ones interest to break the Euro. The Germans would suffer. Italy & Spain would be vulnerable and the Greeks won't leave voluntarily. In short it won't happen.
