Greece in a nutshell. In case a country goes bankrupt, you usually need: A) fiscal austerity, B) economic reforms, and C) debt restructuring.
Greece (now leftist) wants little A and B, and insists on more C.
Germany (technocrats) wants a lot of A and B, and no more C.
France (socialist-democrats) wants little A and B, but likely no C.
IMF (neoliberals) wants a lot of A, B, and C by others.
ECB (bank) wants a solvent Greece, Greek banks, and a deal.
That's about it.
