Suppose you consider Tsipras an incompetent twerp. Suppose you dearly want to see Syriza out of power. Suppose, even, that you welcome the prospect of pushing those annoying Greeks out of the euro.

Even if all of that is true, this Eurogroup list of demands is madness. The trending hashtag ThisIsACoup is exactly right. This goes beyond harsh into pure vindictiveness, complete destruction of national sovereignty, and no hope of relief. It is, presumably, meant to be an offer Greece can’t accept; but even so, it’s a grotesque betrayal of everything the European project was supposed to stand for.

Can anything pull Europe back from the brink? Word is that Mario Draghi is trying to reintroduce some sanity, that Hollande is finally showing a bit of the pushback against German morality-play economics that he so signally failed to supply in the past. But much of the damage has already been done. Who will ever trust Germany’s good intentions after this?

In a way, the economics have almost become secondary. But still, let’s be clear: what we’ve learned these past couple of weeks is that being a member of the eurozone means that the creditors can destroy your economy if you step out of line. This has no bearing at all on the underlying economics of austerity. It’s as true as ever that imposing harsh austerity without debt relief is a doomed policy no matter how willing the country is to accept suffering. And this in turn means that even a complete Greek capitulation would be a dead end.

Can Greece pull off a successful exit? Will Germany try to block a recovery? (Sorry, but that’s the kind of thing we must now ask.)

The European project — a project I have always praised and supported — has just been dealt a terrible, perhaps fatal blow. And whatever you think of Syriza, or Greece, it wasn’t the Greeks who did it.
