MADRID | JP Marín Arrese | The markets have shown utter dismay at the dim prospects of the euro zone striking a deal that would cut short uncertainties over the current Greek imbroglio. Tsipras seems ready to fight until the very end in a bid to undermine his European partners. As the Brussels bureaucracy works feverishly to broker an honourable truce, Tsipras appears increasingly reluctant to offer anything short of unconditional surrender. His blunt refusal of any rescue linked to the current conditions is eroding confidence in the Greek government’s political wisdom, its brand of refined brinkmanship seems unlikely to bring Athens to a less intractable stance. A devastating crisis may loom ahead should the sides fail to yield ground in the current tug-of-war.
