end for euro?

Does european bailout mean end for euro? This is what some are saying. Things are ugly right now. Problems are getting worse. Stability is a major concern. I wonder about the future of greece. Next in line seems to be spain. It has 20% unemployment right now. Definite that this is not a good recipe. When will things improve? This could be the end of the eurozone. In fact, it could be the end of a common europe.
