Euro zone aid for Greece is only short-term solution

"This is not a defining moment for the euro zone. What is concerning is that at every stage in recent weeks the EU has been resisting the inevitable and has been forced into action by financial markets," said Simon Tilford, an economic analyst at the London based Centre for European Reform think tank. "The immediate danger is averted but very little has been done to address longer-term problems. This is not a blueprint for additional crises. It might work for another small country like Portugal but not a big country like Italy or Spain."
