In Cannes, leaders from the world's 20 largest economic nations are meeting to discuss the most pressing fiscal matters across the globe. On top of that list is Greece and the high-stakes political gamesmanship of the country's Prime Minister George Papandreou. Papandreou called off a plan to hold a referendum on his country's loan deal with the European Union Thursday after he gained new support for the deal from the opposition. Greece is in a tense political stalemate as its fate with the euro zone hangs in the balance. Papandreou is trying avoid a economic catastrophe as he faces calls for his resignation and a no-confidence vote on Friday. Papandreou's political brinkmanship has renewed questions about the instability of the euro zone and the destabilizing roles of deeply indebted countries.
