jesus. Varoufakis is doing the only logical thing to do. If greece stays in the euro, they will be paying debts forever. (like the irish do).
The problem is that Europe doesnt accept that the money is lost (it was lost by the banks investing in greece, and the Eu-governments reimbursed them), because they fear there own voters for what they did (bailing out the banks with tax money). Thats why they cant make a proper deal with greece.
