There's no way any country in the world could keep up with troika's bailout terms given the damage these terms did to the economy.
The IMF already noted that the "plan" was wrong. Every single forecast was out by a huge margin, what exactly more do we need to die? Stop breathing?
WHat Varoufakis says is that we don't want money under terms the country can't honor, and the troika asks repeadetly for him to be removed. Maybe someone like Stournaras who signs any paper without asking questions would be more fit.
