In reality, both Greece and the rest of the eurozone should treat the Greek vote as an opportunity to rethink the malfunctioning euro project. They can find a common interest in making it as painless as possible for Greece to leave the euro — both to lessen the suffering of ordinary Greek people and to establish a model that other countries might be able to follow in the future. For Greece is not the only country struggling to cope with a currency union. The current crisis could be a chance to show there are ways out of the euro that could benefit all sides — those that leave the currency union and those that stay.
