From the comments, on Grexit

Syriza will deal. As with the “troika,” there’ll be a change in vocabulary so they can minimize loss of face, but they’ll deal. They simply don’t have a choice if they plan to remain in power very long.

Not only do most Greeks oppose Grexit, but the sympathies of far too much of the Greek army and law enforcement agencies are, frankly, not with Syriza. Nobody knows if they’ll acquiesce to being paid in drachmae and not deutschmarks by the grandsons of “anarcho-communists.”

Neither, incidentally, do the rest of the EU gain anything from another failed state and/or Russian client in the Balkans.

By now, they’ll have told Varoufakis, in some form, formally (during discussions) and informally (during networking breaks):

“Yanis. We get it. You’ve made your point. Greece is a miserable place right now. There’s a lot of it going around. Listen to us. Please. We secretly care about Greece enough not to want another 1967 or Balkan war. You don’t have to believe that, but it’s true.

“We may have overdone it. Fine. We’re flexible. But seriously—if you walk away we’re looking at another 1967 when you run out of cash. Greece will become an even more miserable place real fast. Do you want our help or not?”

That is from Richard Besserer.
