Tsipras’ victory presents the troika—a consortium consisting of the European Central Bank, the European Commission, and the International Monetary Fund—with a
series of unappetizing options. If the troika gives in and writes down Greek debt, then other, larger countries—such as Spain—will have an incentive to negotiate a similar deal, triggering a major financial headache in Brussels and Frankfurt. If the troika refuses, then Greece is likely to default on its debt obligations this year and be forced to exit the eurozone—a fate that neither Tsipras nor the European leadership say they want.
Either way, the events in Greece signal that Europe’s long, failed experiment with austerity is cracking. In addition to Syriza, anti-austerity parties have grown popular in Spain, where opinion polls show Pablo Iglesias’ Podemos with 20 percent support. And Euroskeptic parties gained heavily in last years’s European parliament elections, particularly Marine Le Pen’s National Front Party, which has campaigned against fiscal austerity in France.
