My impression is that is does not _want_ to take Greece out of the euro. He hoped that the 'institutions' would change their mind, but they didn't. So now it is a choice between trying to keep going despite impossible conditions and a huge debt burden that can never be repaid or leaving the eurozone with a small chance that the EU gets scared and actually changes course. In any case, leaving the euro is bad for Greece and possibly fatal for the eurosystem, but for Greece it looks increasingly like the lesser evil.
