This, in a nutshell, was the obstacle. Syriza wanted a new arrangement in which the rest of the EU would trust it to deliver on its promises. The rest of the EU wanted Syriza to prove its trustworthiness by completing the current programme. Deadlock.
Balanced and interesting analysis by Frances Coppola of the deal between Greece and Eurozone leaders. But by trying to win trust from the austerity elites, could Syriza lose trust of its voters?
Seems to me, the endgame has just been postponed by four months.
