To keep Greece in the euro zone, effectively you need a transfer union, you have to realize that the problems of Greece are long-term, it’s going to take 10 to 20 years to do the austerity and the reform to stabilize Greece and therefore you have to give money and you have to be patient.
If you’re willing to do that for the sake of keeping the euro zone together, whether it’s economic reasons or political or geo political or foreign policy then Greece has a chance. - in The WSJ
