Greece needs to be cut loose. Plus another fringe countries.
Ireland? No -- it's doing well. It dug itself out of the hole and was very disciplined.
Spain? No, it's improving. They have troubles still, but they are growing economically and have put in strong reforms
Portugal? They are trying hard. They are weak and would always be weak
italy? Maybe.
France? Definitely :-P -- but the latter two aren't "fringe"
Funny how nobody says that the euro should never have been established in the first place.
