The suggestion to postpone elections and install a technocrat government is a distinction without a difference from the previous floating balloon out of Berlin that Greece give up its rights to manage its economy to someone in Brussels. The fact that Brussels was complicit in allowing Greece to play fast and loose with its economy so long as times were good doesn't bode well for the idea - but that's another story.
However, the venomous recent exchanges show that there is no “Europe” in Europe. Citizens in Germany, France, Italy and the other 24 EU members simply do not think of themselves as European first. Which is why Greece will eventually default and leave the Eurozone – paving the way for the slow motion economic and political unraveling of the EU unless a new approach is taken very, very soon. In addition, the concept of installing unelected technocrats to run, at a minimum, the economic policies of a nation has been tried before and didn’t go too well by the time it ended in 1991.
