Is it the end of the Euro?

If Greece leaves the Euro by itself that won't be the end of the Euro. However, if Greece leaving the Euro and if Greece's economic situation doesn't get any worse than it has been already, it is possible that Italy and Spain might leave the Euro too. And if they leave it just might be the beginning of the end for the Euro.

I suppose it could be eventually just Germany on the Euro and no other, and if things got better economically it is an outside possibility that one by one they might go back on the Euro too. However, that is a real long shot.
