I agree with you. I guess only time will tell. But just to speculate maybe Schäuble is really arrogant and he knows no one would believe Varoufakis. Maybe he said that in a very diplomatic way and Varoufakis was quoting what he believe the minister said. It is also naive to think that the french would be completly in the dark about german intentions. That's why Hollande is completly against the Grexit. But you are right its implausible, and even if true Varoufakis lost his oportunity. I do believe that there are some forces looking forward to implement a fiscal union and that they are unstoppable. I only wish they do not seek to prostrate europe to achieve their goal.
