Varoufakis himself said as much in his short statement to the media: "Soon after the announcement of the referendum results, I was made aware of a certain preference by some Eurogroup participants, and assorted 'partners', for my… 'absence' from its meetings; an idea that the Prime Minister [Alexis Tsipras] judged to be potentially helpful to him in reaching an agreement. For this reason I am leaving the Ministry of Finance today," he stated. "I consider it my duty to help Alexis Tsipras exploit, as he sees fit, the capital that the Greek people granted us through yesterday’s referendum."
The Germans, and each of their lapdogs in turn, will announce that there will be no reduction in the conditions demanded of Greece even if Tsipras arrives with some new agreement that he can capitulate to. Germany and the others know that Greece is a small fry but that if they are appeased 'contagion' will be near instant and that, if allowed to proceed, would be the end of their leeching the wealth from their poorer cousins.
It was a great party in Greece last night but today it's widely understood that it was at best a symbolic victory. SYRIZA needed to stop waffling a long time ago. SYRIZA and Tsipras must either eat shit and stick with the EU come what may or hit the road and come what may. The Greeks, and they are the majority, are living an 'Alice in Wonderland' existence if they think Germany et al will budge because of the OXI vote. The referendum question was purposefully vague because SYRIZA had to get an OXI answer without confronting the 'Alice' effect.
Argentina didn't flip-flop they made a choice and DID it, same with Iceland. The NWO corporate/banking Empire won't give Greece a break. Greece needs, to declare bankruptcy and get out, then jail the oligarchs, generals, elites etc before the CIA/NATO uses them and their assured whining to justify whatever gruesome tactics they'll try next.
Argentina was saved by Chavez, Iceland was saved by being small and self-contained for centuries, Greece needs China/BRICS who'll only help if/when Greece declares total independence.
