This is, and presumably was intended to be, an offer Alexis Tsipras, the Greek prime minister, can’t accept, because it would destroy his political reason for being. The purpose must therefore be to drive him from office, which will probably happen if Greek voters fear confrontation with the troika enough to vote yes next week.
But they shouldn’t, for three reasons. First, we now know that ever-harsher austerity is a dead end: after five years Greece is in worse shape than ever. Second, much and perhaps most of the feared chaos from Grexit has already happened. With banks closed and capital controls imposed, there’s not that much more damage to be done.
Finally, acceding to the troika’s ultimatum would represent the final abandonment of any pretense of Greek independence.
