Is the Greece-Euro Relationship Beyond Repair?

With both sides said to be drawing up final proposals, and a definitive debt crunch thought to be imminent, the months of brinkmanship over Greece may at last be drawing to a close. But who knows, really? You might think making this shambles any worse would challenge even these principals. I don't know. I think they're up to it.

Whatever happens, take a moment to reflect on the damage already done during the stalemate -- damage that will persist even if the brink isn't crossed, and a deal is done to avoid a Greek default plus exit from the euro system.
