The Greek government is too much. They probably think they are leading a union:
Stathis Kouvelakis said:https://www.jacobinmag.com/2015/07/tsipras-varoufakis-kouvelakis-syriza-euro-debt/
Two things have to be said at this point. The first is that Tsipras and most of the people close to him thought it was going to be a walk in the park. And that was pretty much the case before the closure of the banks. The general sense was that the referendum would be won overwhelmingly, by over 70 percent.
This was quite realistic, without the banks closing down the referendum would have been easily won, but the political significance of No would have been changed, because it would have happened without the confrontational and dramatic atmosphere created by the bank closure and the reaction of the Europeans.
What happened in that cabinet meeting was that a certain number of people the rightist wing of the government, lead by Deputy Prime Minister Giannis Dragasakis disagreed with the move. Dragasakis is actually the person who has been monitoring the whole negotiation process on the Greek side. Everyone on the negotiating team with the exception of the new finance minister, Euclid Tsakalotos, are his people and he was the most prominent of those in the cabinet who really wanted to get rid of Varoufakis.
This wing thought that the referendum was a high-risk proposal, and they understood, in a way that Tsipras did not, that this was going to be a very confrontational move that would trigger a harsh reaction from the European side and they were proved right.
They were also afraid about the dynamic from below that would be released by this initiative. On the other hand, the Left Platforms leader and minister of energy and productive reconstruction, Panagiotis Lafazanis said that the referendum was the right decision, albeit one that came too late, but he also warned that this amounted to a declaration of war, that the other side would cut off the liquidity and we should expect within days to have the banks closed. Most of those present just laughed at this suggestion.
